According to the behind-the-scenes book The Making of Jurassic Park: An Adventure 65 million Years in the Making, the infamous roar of The Tyrannosaurus' were a composite mix of a dog, penguin, tiger's snarl, alligators gurgle, and a baby elephants squeal . The very deep alligator vocals acted as the low-frequency element of the final roar. However, as Gary Rydstrom stresses, the key part of the sound is the high-frequency element: the baby elephant. Rydstrom describes how, during the recording session, the baby elephant only did the iconic "cute high-pitched scream" that forms the basis of every T. rex roar in the film once. "We kept trying to get it to do it again, and the handlers were saying, 'We never heard it do that before; that's a weird sound.'" As Rydstrom stresses, the introduction of the T. rex is a scene expressly planned around sound design. "I think maybe other directors would have had a shock moment where you see the T. rex show up out of the blue Spielberg was great in the T. rex scene by getting several minutes of tension because you knew what was coming. And you knew it because you heard it before you saw it it's nice when movies think about sound that way."

This movie and the book generated so much interest in dinosaurs that the study of paleontology has had a record increase in students.

The T. Rex occasionally malfunctioned, due to the rain. Producer Kathleen Kennedy recalls, "The T. Rex went into the heebie-jeebies sometimes. Scared the crap out of us. We'd be, like, eating lunch, and all of a sudden a T. Rex would come alive. At first we didn't know what was happening, and then we realized it was the rain. You'd hear people start screaming."

When Hurricane Iniki hit, the cast and crew were all required to move into the ballroom of the hotel in which they were staying. Sir Richard Attenborough, however, stayed in his hotel room and slept through the entire event. When asked how he could possibly have done this, Attenborough replied, "My dear boy, I survived the blitz!"

Michael Crichton intended John Hammond to be "a dark Walt Disney". However, while possibly unintentional, the character is also similar to PT Barnum.

The guests' encounter with the sick Triceratops ends without any clear explanation as to why the animal is sick. Michael Crichton's original novel and the screenplay, however, include an explanation: the Stegosaurus/Triceratops lacked suitable teeth for grinding food, and so, like birds, would swallow rocks and use them as gizzard stones. In the digestive tract, these rocks would grind the food to aid in digestion. After six weeks, the rocks would become too smooth to be useful, and the animal would regurgitate them. When finding and eating new rocks to use, the animal would also swallow West Indian Lilac berries. The fact that the berries and stones are regurgitated explains why Ellie never finds traces of them in the animal's excrement.

(at around 25 mins) The Mr. DNA cartoon was Steven Spielberg's way of condensing much of the novel's exposition into a few minutes.

Director Steven Spielberg wanted the velociraptors to be about ten feet tall, which was taller than they were known to be. According to an artist involved in pre-production, Spielberg requested this change because he was unhappy with the size of what was considered the largest dromaeosaurid at the time, Deinonychus, and wanted it to be bigger. Another reason was to make the raptor more menacing. During filming, paleontologists actually uncovered ten-foot-tall specimens of raptors called Utahraptors. Spielberg also wanted the dinosaurs to be birdlike, for example, snapping to attention like a chicken. He wanted the Raptors to turn their heads so they could look behind them to make them have a scarier appearance. Spielberg likened the Raptor tapping its claw to Morse code to any Raptor listening.

Universal Pictures paid Michael Crichton $2 million for the rights to his novel before it was even published.

When Michael Crichton was asked why the novel has "Jurassic" in the title, and has a dinosaur from the Cretaceous period on the cover, he replied that had never occurred to him, and admitted "that was just the best looking design".

Before the book was published, Michael Crichton demanded a non-negotiable fee of $1.5 million, as well as a substantial percentage of the gross.

Steven Spielberg was in the very early stages of pre-production for the movie "ER" (based on a Michael Crichton novel) when he heard about the "Jurassic Park" book. He subsequently dumped what he was doing to make this movie. Afterwards, he returned to "ER" and helped develop it into the hit television series ER (1994).

All of the cast were given a Raptor model, signed by director Steven Spielberg as a gift. It looked very frightening, and Ariana Richards has it in her house to shock anyone coming in, like a guard at the gate. Jeff Goldblum's model has a prime spot in his house, and is a cherished object. Laura Dern put her Raptor model in her son's room near his crib. When he was older and saw it he screamed like never before. She had to put it in storage, but hopes one day, the two will be friends.

Ariana Richards' audition consisted of standing in front of a camera and screaming wildly. Steven Spielberg "wanted to see how she could show fear." Richards remembers, "I heard later on that Steven had watched a few girls on tape that day, and I was the only one who ended up waking his sleeping wife off the couch, and she came running through the hallway to see if the kids were all right."

The job of animating the full dinosaurs was first given to Phil Tippett, who did several previsualizations with stop-motion animation (where models are slightly moved in between shooting separate frames). Motion blur would be digitally added to make the movements seem less jerky and more convincing. However, ILM visual effects artists Steve 'Spaz' Williams and Mark A.Z. Dippé suggested that most of the full-size dinosaurs could be fully animated on computer from head to toe, although their boss Dennis Muren told them that they could never do a better job than Tippett. They proceeded to create a test animation of a skeletal T-Rex anyway, which was shown to Kathleen Kennedy when she visited ILM. Kennedy informed Steven Spielberg, who was intrigued and ordered another test reel. He was blown away by the final result, where a fully fleshed T. Rex walks through a desert. He and Tippett looked at each other and Tippett said, "I think we're extinct". Spielberg liked the line and gave it to Jeff Goldblum to say to Sam Neill in the Visitor's Center. Tippett later stated that he was genuinely physically sick from feeling obsolete, and left the set for 10 days, but he was later hired to help design the computer-generated dinosaurs' movements.

John Williams scored the movie at the end of February 1993 and recorded it a month later. He felt he needed to write "pieces that would convey a sense of awe and fascination, given it dealt with the overwhelming happiness and excitement that would emerge from seeing live dinosaurs."

After making this movie, Ariana Richards developed a great interest in dinosaurs and assisted Jack Horner, paleontologist, advisor for this movie, and the inspiration for the character of Dr. Grant, on an actual dinosaur dig in Montana the following summer.

The crew had to have safety meetings about the T. Rex. It weighed 12,000 pounds, and was extremely powerful. They used flashing lights to announce when it was about to come on, to alert the crew, because if you stood next to it and the head went by at speed, it felt like a bus going by.

(at around 1h 3 mins) When the audience first sees the T. Rex, director Steven Spielberg wanted it from inside the SUVs so the audience feels like they're experiencing it right there with the characters and feeling their fear.

James Cameron has stated that he wanted to make this movie, but the rights were bought "a few hours" before he could bid. Upon seeing this movie, Cameron realized that Spielberg was the better choice to direct it, as his version would've been much more violent ("Aliens (1986) with dinosaurs") which "wouldn't have been fair" to children, who relate to dinosaurs. The visual effects were directly influenced by Cameron's Terminator 2: Judgment Day (1991).

In 2005, paleontologist Dr. Mary Schweitzer discovered red blood cells and soft tissue in the fossilized bones of a T. Rex, meaning dinosaur cloning may someday become a reality.

Steven Spielberg liked the dinosaurs to do behavioral things that had nothing to do with the plot, like stopping to scratch, something he learned on E.T. the Extra-Terrestrial (1982).

(at around 47 mins) While discussing chaos theory, Malcolm (Jeff Goldblum) shamelessly flirts with Ellie (Laura Dern). After meeting on this movie, the two began a romantic relationship, and were engaged for two years before breaking up. Goldblum is famous for striking up relationships with co-stars.

Director Steven Spielberg oversaw the post-production of this movie via video link while in Poland filming the Holocaust-themed Schindler's List (1993). He later called it one of the hardest times in his life as a filmmaker, and it took such an emotional toll on him that his enthusiasm for this movie had almost waned. He said that he needed an hour per day to muster up the energy to comment on digital dinosaurs and answer trivial questions from the special effects crew.

Despite his prominent billing, BD Wong has less than two minutes of screentime. He is, however, the only cast member of this movie to reprise his role in Jurassic World (2015). Wong and Jeff Goldblum reprised their roles in Jurassic World: Fallen Kingdom (2018). In 2022, Sam Neil, Laura Dern, Jeff Goldblum, and BD Wong joined Chris Pratt and Bryce Dallas Howard for Jurassic World Dominion. All had important roles in the story. Dodgson, the man who pays Nedry to steal the embryos, also returns, but is played by a different actor.

This movie opened on Friday, June 11, 1993, and broke box office records its first weekend, with $47 million. It eventually went on to make more than $900 million worldwide. David Koepp remembers the day it opened: "I was in New York and I walked to the Ziegfeld (Theatre) to see how it was doing. The guy comes out and announces to the big line, 'Ladies and gentlemen, the seven o'clock show of Jurassic Park is sold out.' And people go, 'Oooh.' And he goes, 'Also the ten o'clock show is sold out.' And they went, 'Ooooooh.' 'And also Saturday night's seven and ten o'clock shows are also sold out.' And I was like, 'I'm not an expert, but I think this is very good.'"

Despite being called "Jurassic Park", the dinosaurs only have around fifteen minutes of screen time: nine minutes are Stan Winston's animatronics, and six minutes of it is Industrial Light & Magic CGI. This means only around 11% of the film is dedicated to dinosaur scenes.

Michael Crichton wrote the novel because of his concern for the rise of scientism, and the exploration of bio-genetics for the sake of profit.

The most difficult effect to pull off was the vibrating rings of water. Steven Spielberg wanted the T. Rex to announce its presence somehow before the audience saw it, and got the idea from watching the mirror in his car vibrate from the bass effects whilst listening to Earth, Wind and Fire. When Michael Lantieri tried to replicate that with water, it was harder than any of the dinosaur effects. Nobody knew how to do it, but told Spielberg they could. The night before the shoot, Lantieri put a glass of water on a guitar and when he plucked the strings, that did it. So for the scene, they fed guitar strings under the dashboard to get the effect. A man on the floor plucked the strings to achieve the effect.

The Triceratops dung (at around 52 mins) didn't smell at all. It was made of clay, mud, and straw. It was drizzled in honey and papayas so flies would swarm near it.

Michael Crichton estimated that the screenplay has about ten to twenty percent of the novel's content.

The groundbreaking effects were the highest point of praise from critics. Stanley Kauffmann wrote that it made King Kong (1933) "look like something from a Macy's Thanksgiving Day parade". However, the human characters did receive flack from critics, even from those who gave the film a positive review. Peter Travers felt the characters were forgettable, describing them as "dry bones" and "nonentities" with Roger Ebert likewise saying, "the movie is lacking other qualities that it needs even more, such as a sense of awe and wonderment, and strong human story values". Kenneth Turan wrote that the effects "left no time to make the people similarly believable or involving." Variety noted that despite the "one-dimensional" characters and "clunky" story it delivered and is now considered a classic Hollywood blockbuster.

Steven Spielberg received $250 million from this movie's gross and profit participations.

During the scenes with the T. Rex, Steven Spielberg would roar like one through the megaphone. The cast cracked up whenever he did that. Sam Neill stated, "That was kind of more funny than anything, and the acting part was not laughing. It's not easy."

Michael Crichton said that his views on science and genetic engineering are largely expressed by Ian Malcolm. Steven Spielberg saw many parallels to himself in the character of John Hammond. Fittingly, he cast a fellow filmmaker in the role, who begins his tour of the park by showing a movie in which he also acts. While Malcolm is dressed entirely in black, Hammond wears all white.

Ian ( Jeff Goldblum ) says the line "must go faster" while being chased (at around 1h 20 mins) by a dinosaur. In Independence Day (1996), co-executive producer, co-writer and director Roland Emmerich liked it so much, he had Goldblum say it when he and Will Smith were escaping the mothership.

Shortly after Nedry makes his first appearance in the control room (at around 43 mins), during his argument with Hammond, one can clearly see Jaws (1975) playing in a small video window on one of Nedry's computer screens. That movie was, of course, directed by Steven Spielberg and was Spielberg's first experiment with animatronic animals, namely the giant shark they built for the movie.

(at around 1h 7 mins) Sam Neill injured his hand lighting the flare he uses to distract the Tyrannosaur. According to Neill, "It dropped some burning phosphorous on me and got under my watch and took a chunk of my arm out."

In this movie, Steven Spielberg directs the man who beat him to the Best Director Oscar in 1983 (Sir Richard Attenborough, whose movie Gandhi (1982) also beat Spielberg's E.T. the Extra-Terrestrial (1982) as Best Picture).

Grossed $402 million in the U.S., and just over $1 billion worldwide. Steven Spielberg made $250 million from this movie, the largest sum any individual has made from a movie.

The novel was published in 1990. However, pre-production of the film began in 1989, using only Michael Crichton's manuscript. It was widely believed that the book would be such a hit that it would make an outstanding movie. It turns out that assumption was correct.

When the Utahraptor was discovered right before the movie's release, which had a similar height to the Raptors depicted in this movie, Stan Winston joked, "We made it, then they discovered it, that still boggles my mind."

Ariana Richards was upset by the fact that an action figure of her character was not produced. (Kenner only made dolls of Grant, Sattler, Muldoon, Nedry, Tim, and eventually Malcolm.)

(at around 1h 40 mins) Laura Dern was crying for real and was genuinely frightened in the scene which Ellie (Dern) encounters the raptor in the maintenance shed scene. Because the way the shot had been constructed genuinely terrified her.

Steven Spielberg delayed the beginning of filming by several weeks to get the cast he wanted. First he allowed Sir Richard Attenborough to finish post-production on Chaplin (1992) before committing to this movie. He also waited until Sam Neill could finish filming Family Pictures (1993). Neill ended up only having a weekend off between finishing that movie and starting this one.

The kitchen scene was Ariana Richards' favorite scene. It was filmed in two weeks with Raptors there most of the time, and a man in a suit some of the time. Anyone in a Raptor suit could only do it for up to fifteen minutes, because they were bent over in a downhill skiing position, which is very physical. The Raptor clicking its toenails was done with a puppeteer walking on Raptor legs.

Generally speaking, any shot of a full dinosaur was computer-generated, but shots of parts of dinosaurs were of animatronics.

The Dilophosaurus' fictitious venom-spitting ability and its neck-frill became so iconic that almost every other appearance of the animal in popular media, including many Dilophosaurus toys feature at least one or both of these aspects. Some even leave out the dinosaur's striking double-crests from which it got its name ("two-crested lizard"). In reality, the spitting ability was only made up by Michael Crichton, while adding the frill was Steven Spielberg's idea. In the late 20th century, scientists mistakenly thought Dilophosaurus had weak jaws due to the animal's incomplete, distorted and badly reconstructed fossil skull, and many books at the time claimed it couldn't have killed prey with its jaws. Crichton based his idea about venom-spitting on these outdated theories, proposing that Dilophosaurus might have used venom to hunt. This hypothesis also served to demonstrate that real life dinosaurs could have looked and behaved much differently than what people believed by studying their bones - this idea turned out to be true when many dinosaurs, mainly raptors, were discovered to have had feathers during the 1990s and 2000s. In 2020, Dilophosaurus was also given a scientific makeover. More detailed studies revealed it had significantly thicker, keratin-covered crests filled with air sacs, rather than the thin plate-like crests seen in the film, and robust jaws that would have been perfectly suitable to kill prey, meaning it would not have needed venom. The Dilophosaurus'fictional features are consequences of the dinosaur being not pure-blooded. The frilled lizard's DNA is responsible for the neck frill, and the spitting snake's DNA is responsible for the venom.

Except for some very brief glimpses in the opening scene, the adult velociraptors, often cited as the most memorable dinosaurs in this movie, don't make an on-screen appearance until over one hour and forty-three minutes into the movie.

Steven Spielberg changed the climax a few weeks before the end of the shoot. When he saw early visual effects footage of the first two T. Rex sequences, he realized that more was possible. The original climax involved the Raptors being killed by the T. Rex skeleton in the Visitors Center, but Spielberg felt the audience would hate him if the T. Rex didn't make one final heroic appearance, since he considered the T. Rex the star of the movie, hence the Raptor and T. Rex fight. The new climax was completely computer-animated unlike the first T. Rex attack. First, they enacted it, and then added in the effects. It was the last scene to be filmed.

Merely three years after the movie wrapped, it was discovered that many carnivorous dinosaurs were mostly or fully feathered, and some had actual wings rather than arms, implying that Dr. Grant was right, they shared a common ancestor with birds. A smaller relative of Velociraptor called Microraptor, discovered in 2000, had four wings, using its front limbs to glide between trees while the wings on its legs acted as a sort of rudder. Evidence of modern bird-style wing feathers on Velociraptor were described in 2007. Scientists however have already suspected that "raptors" had feathers well before the movie was made. Paleontologist and artist Gregory Paul, whose scientific ideas inspired the Jurassic Park novel, illustrated raptors with feathers in the mid 1980s. In the book, the Maiasaura hatchlings (which were not included in the film) also had fluffy feathers. Tyrannosaurus on the other hand caused a lot of debates, as its ancestors and distant relatives were definitely coated in primitive, fuzz-like feathers but no physical evidence exists for T. rex itself having fuzz. Scientists think it either lost the need for feathers, or it was feathered when young and gradually shed them as it grew.

After Joseph Mazzello was turned down for the role of Jack Banning in Steven Spielberg's Hook (1991) for being too young, Spielberg told Mazzello that he was still impressed with his audition and would try to cast him in a future project. Mazzello was then cast as Tim in this movie. As Mazzello recalls, "Steven had me screentest with Robin Williams and Dustin Hoffman for Hook (1991). I was just too young for the role. And because of that, Steven came up to me and said, 'Don't worry about it, Joey. I'm going to get you in a movie this summer.' Not only a nice promise to get, but to have it be one of the biggest box-office smashes of all time? That's a pretty good trade." Mazzello's casting led Spielberg to reverse the ages of the children, as he decided that casting a girl younger than Mazzello would be too young to be placed in danger. Lex was therefore made the older child, and the computer expert as well. In Michael Crichton's original novel, Tim is older, and is both the dinosaur and computer enthusiast.

The T. Rex model was controlled with a waldo, a very small replica to manipulate it to get it to respond exactly. They weren't supposed to get it wet, because it was fine-tuned into how much it weighed, but once they shot the rain scene, it stopped responding. Between takes they had to towel it down to dry it out at night. When it attacked Lex and Tim, it lost some of its teeth on top of the car. They tried gluing them back in, but one refused to after twenty minutes. There's a shot where if you pause it in the right place you can see it's missing a tooth.

Paleontologist Robert Bakker was blown away by the movie's dinosaurs. Tim name-checks Bakker when talking to Grant.

Michael Crichton wrote the novel in 1990, but he first got the idea in 1981. Crichton wasn't sure how to plausibly bring dinosaurs back to life until he learned about insects in amber preserving their DNA, which was the breakthrough he had been looking for. He later learned the idea is hypothetically possible. A weevil, containing dinosaur blood from more than sixty-five million years ago was discovered in amber. But DNA quickly breaks down in an insect, which is why Jurassic Park's dinosaurs are more fictional.

The sound of the T. Rex's footsteps were created by cut sequoias crashing to the ground.

(at around 1h 29 mins) When Grant feeds the Brachiosaur, the head was twelve feet high, on a dolly, so it could move in on wheels, and the actors and actress would have something to which to react. The Brachiosaur snot was methacryl; Steven Spielberg insisted it be green, if it has a cold. Ariana Richards gets asked about that scene in every Jurassic Park interview; she refuses to talk about it anymore. To create the sound of the sneeze, sound designer Gary Rydstrom used the combination of a whale's blowhole and a fire hose turning on from the Skywalker Ranch Fire Department. For the singing, he slowed down a donkey yodel, and stretched it out into a song.

The Dilophosaurus never walks because it was difficult to get the weight shifting and the movement right. A trench was cut into the floor of the set for the puppeteers, but Steven Spielberg elected to have it just appear instead to make the scene more ominous and surprising. He also wanted more water for the scene coming down the hillside with every fire hydrant going in the studio until they ran out. Michael Lantieri joked every now and then "just splash him with something so he feels there's more water". To this day, Spielberg still feels that scene needed more water. Wayne Knight thought it a miserable scene to shoot; sliding down things, covered in mud, soaking wet, he was three hundred twenty-seven pounds, and he could barely walk, but he loved watching it.

Ian Malcolm (Jeff Goldblum) dresses entirely in black in this movie and The Lost World: Jurassic Park (1997). In the book, he tells Ellie Sattler that he only ever dresses in black and gray, so that he never has to waste time thinking about what to wear. Seth Brundle (Jeff Goldblum) gives the same reason for his monotonous fashion sense in The Fly (1986), an idea that Brundle got from Albert Einstein.

The Dilophosaurus spit (at around 1h 13 mins) used a paintball mechanism that actually spat from the model's mouth; the venom was made out of methacryl and KY Jelly, with some food coloring mixed in.

The sick triceratops was designed with a very colorful pattern on its skin. Once the creature was brought on-location, however, Stan Winston decided that, to be realistic, the animal should be covered with dirt from its surrounding environment.

Steven Spielberg's most commercially successful movie.

(at around 31 mins) "Life, uh, finds a way" is Jeff Goldblum's favorite line.

This was Richard Attenborough's first acting role since The Human Factor (1979) 14 years earlier.

The storm overpowering the park has been read as the movie's theme of trying and failing to control nature.

All of the merchandise (t-shirts, stuffed dinosaurs, lunch boxes, flasks, et cetera) shown in the movie were, in some part, created to be sold with the movie.

Briefly held the box-office record until it was beaten by Titanic (1997).

For the premiere, Steven Spielberg turned up in one of the Jurassic Park tour vehicles. Sam Neill and Jeff Goldblum also attended the premiere.

Dr. Alan Grant was modelled after paleontologist Jack Horner who, like Grant, digs and teaches in Montana, and was also a technical advisor on this movie.

Gallimimus means "fowl mimic". Although Grant never answers Lex's question, Gallimimuses were carnivores, but only went after other dinosaur eggs.

A baby triceratops was built for a scene where one of the kids rides it. Special effects technicians worked on this effect for a year, but the scene was cut at the last minute, as Steven Spielberg thought it would ruin the pacing of the movie. A similar scene, however, was used in Jurassic World (2015).

John Hammond (Sir Richard Attenborough) created the dinosaurs from DNA trapped in amber. He also carried around a cane capped with a mosquito in amber. Attenborough's brother is naturalist David Attenborough, who has his own collection of animals trapped in amber. This was the focus of Natural World (1983) season twenty-two, episode twelve, Natural World: The Amber Time Machine (2004).

Began principal photography on the island of Kauai in August 1992, two years and one month after pre-production. The lush resort made it an ideal setting, but after three weeks filming, Hurricane Iniki came to Kauai, and the crew were asked by the hotel to pack their suitcases, fill their bathtubs in case of a power or water shortage, and to pack a day bag and meet in the hotel ballroom, on the basement level. By 9:00 a.m., the storm hit. Kathleen Kennedy ensured the movie crew had generators for lights and plenty of food and water. They had to be self-sustaining because they moved around on-location all the time. They had to camp out in rows of chaise lounges on the ballroom floor, while the cast and crew heard winds pick up at 4:00 p.m., and rumble by the hotel at nearly one hundred twenty miles per hour. Kennedy likened it to a freight train roaring past. Iniki struck all the sets, leaving no working phones or power on Kauai, so at dawn, Kennedy jogged to the airport to explore their options, where all the windows were blown out in the terminals, and it was full of palm trees, sand, and water. Kennedy hitched a lift to Honolulu on a Salvation Army plane and began organizing from a pay phone. Over twenty-four hours, she coordinated the safe return of the company, and arranged for more than twenty thousand pounds of relief supplies transported from Honolulu and Los Angeles into Kauai. After returning to Los Angeles, this movie resumed production at Universal Studios.

On September 11, 1992, Hurricane Iniki hit the island of Kauai, delaying production. The crew were caught in the very dangerous hurricane, but the filmmakers nevertheless managed to capture shots from the hurricane and used them in the movie (Steven Spielberg convinced Dean Cundey to shoot footage of it before being locked into the hotel ballroom). Many of the crew helped in the clean-up. This incident was the subject of a 2009 episode of The Weather Channel series Storm Stories (2003).

The dinosaurs were billed as the most accurate ever created on film.

(at around 5 mins) When Juanito (Miguel Sandoval) is inspecting the amber encased mosquito at the digsite in the beginning, he says in Spanish, "Qué lindo eres, vas hacer a mucha gente feliz", which in English means, "You are so beautiful, you will make a lot of people happy."

A rattlesnake made the noise of the Dilophosaurus neck rattle, because it was scary to listen to. The cute Dilophosaurus sound was made by the hopping chirps of a swan.

Joseph Mazzello did the freezer scene (at around 1h 50 mins) on his birthday. The Raptor was on wheels and had to be pushed, and the claws hit Mazzello on the forehead. He fell to the floor dizzy but was okay. Steven Spielberg had the whole crew sing "Happy Birthday", so Mazzello considered it his birthday present.

Real Velociraptors were actually barely 1.6 feet tall, much smaller than the ones depicted in the movie. Shortly after the movie release, a dinosaur was discovered in Utah that was almost identical to the Velociraptor in the movie. Although the idea was finally scrapped, one of the proposed names for the new species was "Utahraptor spielbergi".

(at around 1h 20 mins) The T. Rex chasing the Jeep took some engineering. Paleontologists alleged a T. Rex could run up to fifty miles per hour. But the model was too big to run that fast, and its bones couldn't support its weight. So they dialed it down to a more acceptable twenty-five miles per hour. Hammond says it can go thirty-two miles per hour (at around 21 mins).

Phil Tippett became quite depressed when he learned that none of the stop-motion creatures he had been developing would be used in the movie. However, shortly after that decision had been made, Industrial Light & Magic animators discovered they did actually have a use for him. While none of his stop-motion models would be seen in the movie, his techniques were determined to be quite useful in animating the computer-generated dinosaurs, especially given how much research he had put into animal movement. Rather than creating the dinosaur motion using key-frame animation, it was decided to build a stop-motion armature for each computer generated dinosaur and manipulate it as they would for a stop-motion movie. These armatures were specially built with motion-sensors, and linked up to the animated dinosaurs being created on the computer. Thus, the motion of the stop-motion armature was directly translated into the computer-generated version that appears in the final movie.

The last element to make the dinosaurs real was sound. They had to guess what they sounded like because vocal cords wouldn't survive to the present, so Steven Spielberg instructed Gary Rydstrom to make them sound like animals; real, but big and deep. Rydstrom recorded different animals and then pieced them together. The Dilophosaurus was a swan call with a hawk, a rattlesnake, and a howler monkey. Raptors were dolphins, a walrus, and geese that when blended sounded horrific. These sounds were put onto a computer and then played through a keyboard. Rydstrom's favorite scene was when the T. Rex ate a Gallimimus, and it looks up one last time, either to beg for mercy or just to see what's got him; Rydstrom likened it to a dog playing with a chew-toy. As it happens, the T. Rex and the Gallimimus vocals were performed by Rydstrom's Jack Russell terrier, Buster.

The sounds made by the Brachiosaurs were a combination of whale and donkey sounds.

The electric SUVs in this movie are Ford Explorers, but in the novel, they were Toyotas; Steven Spielberg managed to get seven for the movie. The Explorers were modified to create the illusion of automation by hiding the driver in the cargo compartment. The Jeeps were also customized for the shoot. Universal Studios Japan has a replica of one of the Ford Explorers from this movie.

During the Jell-O eating scene (at around 1h 45 mins) with Lex and Tim eating sweets, fruits, and desserts, a crew member held Ariana Richards' elbow and shook her arm to add to her character's terror. She (Richards) asked if she could do it, but they didn't think she'd be able to pull it off in a believable way.

(at around 13 mins) The scene between Nedry and Dodgson has spawned a cult following; there are fan re-creations on YouTube and Electro Tunes sampling the line "We've got Dodgson here!" There are even t-shirts with Dodgson's face on it. Cameron Thor auditioned for the part of Ian Malcolm, but got the much smaller part of Lewis Dodgson. Thor was the one who tracked down the shaving can, for use in the movie. He had to spend endless time in a drug store to find the most photogenic can. He even used it after the audition, because he was so broke.

(at around 22 mins) "Welcome to Jurassic Park" was Sir Richard Attenborough's favorite line.

BD Wong auditioned using pages from the novel, as the script had not been finished yet. As such, he expected Dr. Wu to play as prominent a role in this movie. He didn't find out until production had started that he was only needed for one day.

Two scenes from the book were removed from this movie: an opening sequence with Procompsognathus (Compies) attacking children, because Steven Spielberg deemed it too horrific, and for budget reasons, a sequence with the T. Rex chasing Grant and the children downriver, before being tranquilized by Muldoon. Both sequences were re-worked for the sequels.

The Brachiosaurus scene was the second dinosaur scene with the actors and actresses, and took a long time to film, because Sam Neill and Laura Dern had to react to nothing most of the time, and Steven Spielberg was coming up with new shots on the spot.

Jeff Goldblum regretted that he never got to do any scenes with the adult Raptors until The Lost World: Jurassic Park (1997), although he thought the baby T-Rex was more creepy than cute.

After the twin hits of Jurassic Park and Schindler's List (1993), Steven Spielberg took a rare sabbatical. It was four years before he returned to the director's chair with The Lost World: Jurassic Park (1997).

Michael Crichton's agents circulated the book to six studios and directors. Warner Bros. wanted it for Tim Burton to direct, while Columbia Pictures was planning it for Richard Donner. 20th Century Fox was also interested, and was intending the project for Joe Dante, while Universal Pictures wanted Steven Spielberg to direct. Crichton was reluctant to submit to a bidding war. He instructed his agents to put a set price on the film rights and he could decide who was more likely to actually get the film made. After interviewing all of the prospective directors, he agreed to sell the rights to Universal and Steven Spielberg, who was already his first choice.

In the 3-D version, Steven Spielberg claimed adding leaves to the Jeep chase took the excitement from a seven to a nine.

Wrapped twelve days ahead of schedule, but there was still a lot of work to be done. Steven Spielberg then worked with Michael Kahn to edit the movie, before any dinosaurs were added. They trimmed the movie for weeks, wanting Jurassic Park (1993) to look great without the dinosaurs, before they were added, which would make the movie even greater.

After directing Hook (1991), Steven Spielberg wanted immediately to film Schindler's List (1993). Sid Sheinberg greenlit the film, on the condition that Spielberg make this movie first.

(at around 23 mins) Dr. Malcolm's quip that Sattler's and Grant's jobs are extinct is quoted from what puppeteer Phil Tippett said to Steven Spielberg when he decided to use CGI and not Go-Motion. Spielberg had it put in this movie as a joke.

Many errors were corrected digitally: some stunt people were made to look like the actors and actresses, and in one scene, an entire Ford Explorer was digitally generated.

During the kitchen scene (at around 1h 50 mins), it may seem convenient for Tim that the freezer door is already open, and there is ice on the floor that causes the Raptor to slip. However, it actually makes perfect sense, and shows considerable attention to detail. Since the power had been cut off the night before, the freezer would slowly start to defrost. John Hammond knew this, and it is why he can be seen eating ice cream during his conversation with Ellie Sattler, as he knew it would spoil otherwise. He probably left the freezer door wide open, since there was no power anyway, causing the ice in the freezer to melt away quicker, and form chunks of melting ice on the freezer floor. When Sattler later turns the power back on, this would cause the chunks on the floor to re-freeze, and make the surface very slippery.

Steven Spielberg wanted the T. Rex's roar to sound like a "King Kong" roar, particularly at the climax. King Kong (1933) was one of Spielberg's biggest influences when making this movie.

Was selected for preservation in the National Film Registy by the Library of Congress, in 2018 for being culturally, historically or aesthetically significant.

(at around 1h 23 mins) Steven Spielberg wanted the dinosaurs portrayed as animals and not monsters, hence Grant's line to Lex. Paleontologists were brought in to do that, like Jack Horner and Robert Bakker, two of the world's foremost dinosaur experts. Horner vetoed an idea that Raptors had snake tongues because that would sabotage his theory that they're related to birds.

Jurassic Park's first television broadcast was on May 7, 1995, following the April 26th airing of The Making of 'Jurassic Park' (1995). 68.12 million people tuned in to watch, garnering NBC a thirty-six percent share of all available viewers that night. This movie was the highest-rated theatrical film broadcast by any network, since the April 1987 airing of Trading Places (1983).

The Triceratops scene was a major operation. Most of the dinosaur scenes were shot on soundstages, but Steven Spielberg wanted this scene shot on-location in Hawaii. The puppeteers loved this decision because the dust and the dirt tied it into the environment. It was also the first dinosaur the actors and actresses saw. They were blown away by its realism. Stan Winston's team dug a hole beneath the puppet and eight puppeteers below operated cables and push-rods. The backside of the Triceratops had a door with three or four men inside. The only one of the actors not impressed was Joseph Mazzello, because the first dinosaur he got to see up close didn't do anything. To get the Triceratops to breathe, Gary Rydstrom blew into a toy called a "zube tube" to add the harmonics.

According to Fandango, it would cost approximately $23,432,400,000 to build a real-life Jurassic Park (in 2015 U.S. dollars): $1.5 billion - the cost for the park itself. $10 billion - to purchase an island off the coast of Costa Rica with sixty-six square miles of land (twenty-two square miles for Isla Nublar and forty-four square miles for Isla Sorna). $8 million - research and legal team. $9 million - harvesting dinosaur DNA. $8.5 million - overhead to clone dinosaurs from the DNA. $11 billion a year ($32 million per day) - employee payroll and operations budget. $200 million a year - dinosaur food budget. In total, the estimated yearly operating expenses for Jurassic Park add up to approximately $11.9 billion.

The highest-grossing film of 1993. It outdid Steven Spielberg's own E.T. the Extra-Terrestrial (1982) as the then biggest box-office success in film history (not adjusted for inflation). It would hold that record until Titanic (1997), and then James Cameron would also outperform himself with the release of Avatar (2009).

A study by Western Australia's Murdoch University concluded that DNA cannot survive more than 6.8 million years, a finding that effectively rules out the film's method of replicating dinosaurs. The new study, published in the Proceedings of the Royal Society B in 2012, was based on carbon-dating bones from the moa, an extinct New Zealand bird. The researchers found that the DNA from the bones halved after about five hundred twenty-one years when stored at 13.1 degrees. At minus five degrees, the final fragments of DNA in a bone would disappear after 6.8 million years. As of 2022, this topic is being revisited after something that appears to be DNA from 75 million yr old sample was discovered. Many remain skeptical, insisting that it must be contamination, which is what previous samples were eventually revealed to be. However, it remains inconclusive, and more studies are needed. The oldest confirmed DNA is from a 1.2 million yr old mammoth frozen in permafrost. However, these ancient dna samples are extremely small, and too much of the sequence would be missing to clone from it.

The Brachiosaurs chewing food (something they never did really) was added to make them seem more docile, like a cow chewing her cud. Also, they had limited vocal capabilities, but were given whale song, donkey calls, and penguin noises to make them sound melodic.

Michael Crichton was delighted to be writing the screenplay, as was his custom, but it was one of Steven Spielberg's customs to bring in other writers, which he did, when he hired David Koepp to write the final draft.

On the last night of filming, cast and crew lifted their glasses in a champagne toast and the weary, but enthusiastic Steven Spielberg announced that this movie, after two years in planning, and four months before the cameras, finished on budget, and twelve days ahead of schedule.

Sir Sean Connery was offered the role of John Hammond based on his performance as Professor Henry Jones, Sr. in Indiana Jones and the Last Crusade (1989). He turned it down.

David Koepp trimmed much of the characters' excessive details, because he felt that whenever they started talking about their personal lives, he couldn't care less, and neither would the audience. He instead substituted individual moments like Malcolm flirting with Ellie, making Grant jealous, or Lex's adolescent crush on Grant, who fails to notice.

(at around 20 mins) Laura Dern thought the first scene with the Brachiosaur was very tender. She recalled shooting the scene, where the actors were looking at an X on a piece of paper. Grant loses the power in his legs because Sam Neill thought seeing something so mind boggling would make you faint. When Steven Spielberg first edited the scene, the temp music was the St. Crispin's Day speech from Sir Kenneth Branagh's Henry V (1989). Phil Tippett thought it perfect and said "you did it, you crazy son of a bitch", not knowing that was a line from the movie.

In the book, the sick animal is a Stegosaurus, said by Ian Malcolm to be sick because the Jurassic era air had more oxygen than the Holocene, part of the chaos theory.

Before Steven Spielberg decided to use animatronic dinosaurs and computer graphics imagery, he wanted to use stop motion animation for the dinosaur effects and had Phil Tippett put together a short demo of the kitchen scene using claymation dinosaurs (Barbie dolls were substituted for the actual actors).

There is a whole subplot in the novel regarding Dennis Nedry and his reason for betraying the park. In the book, Nedry is not Hammond's employee, but subcontracted by him to create the park's security system. When Hammond cheats on Nedry's pay, Nedry tries to sue, but Hammond instead creates a smear campaign making Nedry lose customers. In the end, he is forced to work for Hammond for a fraction of his pay. The company Nedry was selling the embryos was also trying to clone dinosaurs, but were way behind In-Gen, so Nedry's move was sort of payback. In the end, the filmmakers decided not to include that plot, since it would create sympathy for Nedry and his rather gruesome death. However, there are elements included in the script that hint at this, including Nedri's comment to Dodgson about Hammond's mistake of being cheap and his argument with Hammond over money. It makes Hammond's continued statement that he "spared no expense" ironic, or it may indicate that he spent money on flashier things park visitors would notice, but skimped on more mundane, but necessary equipment for actually running the park.

It was while supervising post-production on this movie that George Lucas decided that technology was good enough to begin work on the Star Wars prequels. Appropriately, Samuel L. Jackson was able to appear in those movies as well.

This movie revolutionized dinosaur behavior; whereas in previous movies they were slow moving, they were now fast and athletic. This derived from paleontologist Robert Bakker. Another aspect included was dinosaurs are not cold-blooded, but rely on the Sun to be active. Steven Spielberg wanted his dinosaurs to be fast-moving, warm-blooded predators, for example, if a T. Rex in the rain were cold-blooded, it couldn't do anything, hence the scene in the movie.

(at around 1h 5 mins) When the T. Rex turned at the sound of the doorslam, Steven Spielberg wanted a quick turn because "slow isn't scary".

Director Steven Spielberg was worried that computer graphics meant Nintendo type cartoon quality. He originally only wanted the herd of gallimimus dinosaurs to be computer-generated, but upon seeing Industrial Light & Magic's demo animation of a T. Rex chasing a herd of galamides across his ranch, he decided to shoot nearly all the dinosaur scenes using this method. The animation was first plotted on an Amiga Toaster, and rendered for the film by Silicon Graphics' Indigo workstations.

In the original script, the T. Rex skeleton in the lobby was hooked up to pulleys like a giant marionette. In the ending, Grant was going to man the controls and act as puppeteer, using the skeleton's head and feet to crush the raptors.

The gun that game warden Muldoon uses is an Italian Franchi SPAS 12, a commonly used gun in films due to its aesthetic modern appearance. Steven Spielberg kept the gun after the production ended. It is part of his very large, private gun collection, and he had many of the stars sign it. When he invites guests to his home in Beverly Hills, he lets them shoot it.

The "Velociraptors" in both the novel and film were intended to be a closely related dinosaur called Deinonychus. Deinonychus lived in North America and was about 9 foot long, while Velociraptor is known from Mongolia and was only 6 foot long, and had a long, thin, upturned snout. A real Velociraptor would only reach up to a fully grown person's knee or waist. The dinosaur fossil dug up in the beginning of the movie is also a Deinonychus. The confusion between the two names comes from Gregory Paul's famous 1988 book "Predatory Dinosaurs of the World", which author Michael Crichton used as a reference for writing the Jurassic Park novel. In the book, Paul considered Deinonychus to be a species of Velociraptor. This is even mentioned in the Jurassic Park novel, where Dr. Grant explains to Tim that "Deinonychus is now considered one of the Velociraptors..." The theory that the two animals belonged to the same genus was never supported by any other scientist, and by the time of the film, Greg Paul himself had also dismissed it. Still, the incorrect name Velociraptor and its catchy shorthand "raptor" were kept for the movie, though the raptors were named Deinonychus in the film's concept art. In later Jurassic Park-based video games, Deinonychus would be introduced as a separate dinosaur, however none of the dinosaurs seen in the franchise truly resemble an actual Velociraptor.

Scenes of the T. Rex attacking Grant and the kids, while they ride down a river and through a running waterfall, were cut before filming.

To film the scene when the T. Rex ate a Gallimimus, a man waved a long stick with a drawing of a T. Rex head at the end of it. Joseph Mazzello thought it looked amateurish, more like a child's drawing. It made him think of Dr. Ian Malcolm's line "Uh, now eventually you do plan to have dinosaurs, on your dinosaur tour, right?"

Steven Spielberg wanted Judith Barsi for the role of Lex. He'd previously worked with her on The Land Before Time (1988). He was shocked to discover unfortunately that she'd been murdered in 1988 by her own father.

The original idea for Jurassic Park came from Michael Crichton's attempt in 1983 to write a screenplay about a Pterodactyl being cloned from an egg. The screenplay and movie never came to fruition. Originally, Crichton's novel was rejected by his "people", a group of about five or six personal acquaintances, who always read his drafts before he sends them off. After several rejections, Crichton finally figured out what was wrong: he had originally intended for the story to be through the eyes of a child who was at the park when the dinosaurs escaped, which his peers felt was too ridiculous, and could not identify with the character. Crichton re-wrote the story as it is today, and it became a huge hit. (The story also incorporates the "amusement park run amok" element of Crichton's earlier screenplay Westworld (1973).)

(at around 1h 20 mins) The T. Rex chasing the Jeep was the most difficult scene to animate. Steve 'Spaz' Williams had to do research because there's no frame of reference for a running animal of that size. It took two months to figure out how to get it to run, for instance. He would run the sequence backwards to see all of the mistakes. They were also able to use the computer to add little details to authenticate the scene, for example, the T. Rex running through puddles of water and leaving splashes, et cetera. The splashing was filmed individually, and then the computer added it to the T. Rex's footsteps.

(at around 13 mins) As the movie was released in Costa Rica, local theater owners scratched/blurred the San Jose tag during the scene when Nedry waits for his contact in what supposedly was the country's capital, because the local audiences reacted negatively to inaccuracies in the scene's geography.

(at around 1h 40 mins) After Malcolm snatches the radio off of Hammond, and gives Ellie directions on how to get to the power box, Jeff Goldblum doesn't have any more dialogue from that point on.

The T. Rex chasing the Jeep was changed by Steven Spielberg from a scene with them just driving away at the sound of the T. Rex's footsteps.

(at around 1h 35 mins) For the part where the T-Rex catches a Gallimimus and shakes it in her mouth, the sound was taken from sound designer Gary Rydstroms Jack Russell terrier shaking a toy in its mouth.

(at around 3 mins) When Juanito is meeting Gennaro at the beginning when Gennaro is on the raft Juanito says in Spanish "Apuesto mil pesos que se cae" which means in English "I bet a thousand pesos he falls off".

Jim Carrey was considered for the role of Ian Malcolm.

In the original script, Gennaro and Malcolm were combined into one character, and Muldoon survived in the end. In the book, Gennaro and Muldoon survived, and Hammond and Malcolm died (though Malcolm returned in the book "The Lost World" by Michael Crichton, explaining that "The doctors did excellent work.").

The full-sized animatron of the Tyrannosaurus Rex weighed about 13,000 to 15,000 pounds. During the shooting of the initial T. Rex attack scene that took place in a downpour and was shot on a soundstage, the latex that covered the T. Rex puppet absorbed great amounts of water, making it much heavier and harder to control. Technicians worked throughout the night with blow driers trying to dry the latex out. Eventually, they suspended a platform above the T. Rex, out of camera range, to keep the water off of it during filming.

There were so many wires and rigging to control the velociraptor animatrons in the kitchen stalking scene that the children had to literally step over and around them while the scene was being filmed. The kitchen set was greatly expanded from the original design to accommodate the velociraptors. Some reports say that all of the dinosaurs in the kitchen scene were computer-generated.

When the survivors are crawling through vent spaces (at around 1h 55 mins), the computer monitors are shining on the Raptor after them. This is usually mistaken as being the shadows from the air vents. It's the letters GATC, the four letters used to denote the components of DNA.

The scene where Grant, Tim, and Lex meet the herd of Gallimimuses was scheduled to be the last scene shot in Kauai. When Hurricane Iniki hit, filming for this scene had to be postponed. Production returned to California and then, a few weeks later, Sam Neill, Joseph Mazzello, and Ariana Richards had to travel back to Hawaii, but this time to the island of Oahu, to shoot the scene.

Sandra Bullock, Gwyneth Paltrow, Julianne Moore, Helen Hunt, Teri Hatcher, Elizabeth Hurley, and Sherilyn Fenn tested for the role of Ellie Sattler. Moore played Dr. Sarah Harding in The Lost World: Jurassic Park (1997).

(at around 28 mins) According to Foley artist Dennie Thorpe, the sounds of the hatching baby dinosaurs were created by a combination of crushing ice cream cones (egg shell breaking), squishing cantaloupe melon halves (embryonic emergence), goo-smeared pineapple skin (baby dinosaur flesh cleansing).

The casting process was fairly easy. Sir Richard Attenborough was the last to be cast, but he immediately agreed to be in the movie. Attenborough hadn't acted since 1979, but he knew Steven Spielberg was the perfect director for the material after reading the novel.

To emphasize the birdlike qualities of the Gallimimus, the animation focused on the herd of them, instead of individually. To prepare for the scene, the animators ran through an Industrial Light & Magic parking lot, with plastic pipes standing in for the tree they vaulted over in the movie. One of the animators missed the jump and fell over, something that was incorporated into the scene. The sounds of the Gallimimuses were horse squeals.

As of April 2015, the Brontosaurus officially does exist. Researchers from the U.K. and Portugal, analyzed a wealth of evidence, and determined that there is enough variation between the fossils to warrant a separate classification.

Sir Richard Attenborough plays Joseph Mazzello's grandfather. He subsequently cast Mazzello in Shadowlands (1993).

Dr. Wu, in the movie and the novel, seems unaware of the implications of what he's created. Scientists in Michael Crichton novels are often ignorant of the consequences of what they create.

Steven Spielberg remained in contact with Industrial Light & Magic while he was in Poland filming Schindler's List (1993) through teleconferences four times a week. He described the extra workload as "a bipolar experience, with every ounce of intuition on Schindler's List, and every ounce of craft on Jurassic Park". He rented two satellite channels through a Polish television station (for $1.5 million a week) and kept them open at all times, and downloaded, from Hollywood each day, the visuals on one, and the sound through the other. He then spent evenings and weekends working on them with video equipment.

When Steven Spielberg first started working for Universal Pictures, he was asked to give a tour to a special guest who had just sold the rights to one of his books to the studio. The guest turned out to be Michael Crichton, who later sold the film rights for another novel to Universal that Spielberg wound up directing, Jurassic Park. The two later became friends, because he claimed Crichton knew how to blend science with big theatrical concepts.

The best dinosaur movies in the past were done with stop-motion photography, but Steven Spielberg wanted to push the effects envelope. After interviewing every effects shop in town, a cadre of effects people were assembled. Stan Winston created the live-action dinosaurs, which were to be quick, mobile, full-size animals. Winston broke Jurassic Park into three phases; research, design and construction. Winston's team spent a year on research, consulting with paleontologists, museums and hundreds of texts. His artists prepared detailed sketches and renderings, that later led to 1/5th scale sculptures and the twenty-foot T. Rex.

The sounds made by the Dilophosaurus were a combination of the sounds of howler monkeys, hawks, rattlesnakes, and swans. The main cry of the Velicoraptors was a combination of the sounds of elephant seal pups, dolphins and walruses. The elephant seal sounds were recorded at The Marine Mammal Center in Sausalito, California, a marine mammal hospital that rehabilitates and releases sick and injured seals and sea lions.

James Cameron said in an interview he wanted to do the movie with Arnold Schwarzenegger as Grant, Bill Paxton as Malcolm, and Charlton Heston as Hammond.

Classic giant monster films like King Kong (1933) and Godzilla (1954) were major influences on Steven Spielberg and the main reason why he wanted to direct it. Spielberg payed homage to Kong in the film with Dr. Ian Malcolm uttering "What have they got in there? King Kong?" Also, after seeing the Kong puppet on the Universal Studios tour, Spielberg asked the designer to apply the same principles to this movie's dinosaurs, for example, smoothness, muscle tone, et cetera. In the Making of Jurassic Park book, Spielberg described how King of the Monsters version of Godzilla was an influence stating, "Godzilla, of course, was the most masterful of all the dinosaur movies because it made you believe it was really happening".

This is the movie that inspired BBC's Tim Haines to produce the groundbreaking dinosaur documentary series Walking with Dinosaurs (1999) and its various follow-ups. But it also made his and the animators' job at Framestore harder, as people have already had an idea of what dinosaurs "should" look and move like.

To give the 1993 Ford Explorer XLTs the appearance that they were driverless and were running on an electric track, the SUVs were driven by remote from the rear cargo area of the vehicle. The driver was hidden under the Ford Explorer's cargo canvas, which was always pulled closed during filming. To see where to steer the SUV, the driver watched a small television that was fed outside images via two cameras. One camera was mounted on the dash in front of the steering wheel, and the other was mounted on the lower center portion of the front bumper, above a black box. Both cameras can be clearly seen in the movie several times.

At The 66th Annual Academy Awards (1994), Steven Spielberg's Schindler's List (1993) and this movie competed for the Best Sound category. Ultimately, this movie won.

Brachiosaurus is the only dinosaur to be given a possible maximum age. The encyclopedia included with DVD of this movie puts their age at a maximum of two hundred years.

(at around 1h 3 mins) When Gennaro runs into the bathroom, and backs up and lands on the toilet, Martin Ferrero actually did land on the toilet which Steven Spielberg kept in due to its authenticity.

A large photo of J. Robert Oppenheimer (one of the scientists who created the atomic bomb) is displayed on Dennis Nedry's workstation.

The tagline "An Adventure 65 Million Years in the Making" derived from a joke Steven Spielberg made about the thousands of years the mosquito was trapped in amber before being discovered.

Fred Sorenson was the pilot who flew the crew off Kauai when the hurricane hit during production. He played Jock, the pilot who flew Indiana Jones away in the opening scene of Indiana Jones and the Raiders of the Lost Ark (1981), also directed by Steven Spielberg.

In 1993, over fifty CGI dinosaur effects had to be added, an unprecedented number at that time, calling upon the most powerful computers at Industrial Light & Magic (they took up three rooms). They went through millions of cycles, and the animators had to deliver dinosaur performances. Phil Tippett had the animators mime like dinosaurs to convey them better on-screen. Tippett also had the animators design a dinosaur input device to translate movements to the dinosaurs on-screen. Real animal movements were studied too, like iguanas, giraffes, rhinos, crocodiles, elephants, and ostriches were incorporated.

Sam Neill was ultimately cast as Grant three or four weeks before filming began. Neill said that "it all happened real quick. I hadn't read the book, knew nothing about it, hadn't heard anything about it, and in a matter of weeks I'm working with Spielberg."

Grant fashioning a functioning seat belt (at around 17 mins) with only two latches and no latch plate foreshadows a later scene where the dinosaurs are suddenly able to breed, despite that they were all originally female.

(at around 10 mins) Newspaper clippings on the fridge in Grant's trailer read "Space Aliens Stole My Face" and "Dinosaurs On Mars!"

While subtle, Nedry's hillside spill during the dilophosaurus sequence (at around 1h 11 mins) is accompanied by a cartoonish "slide whistle" sound.

No one knew what the Raptors sounded like, so to get an interesting sound, they recorded a young dolphin in heat, recorded underwater; it put him in a certain mood and made a wonderful scream, not at all like a dolphin. When Muldoon was hissed at, that was an agitated goose.

During the Gallimimus scene, Sam Neill, Ariana Richards, and Joseph Mazzello were shown pictures of them first, then went out to the hills of Oahu, Hawaii and told to run and run and run. Neill couldn't visualize the finished scene, but Steven Spielberg had a megaphone strapped to his head and made his feelings known. He worked with all three, trying to find more in the scene than on the page. When the herd turned right, Phil Tippett thought Mazzello should say "I think we're going to get flocked!" Spielberg said no and changed it to "They're uh...they're flocking this way." The log the Gallimimuses touched were painstakingly rigged by wires and miniature explosives so when Alan, Lex, and Tim hid behind it, crew members shook it to make it vibrate.

(at around 8 mins) When Dr. Grant is talking to the boy in the beginning of the movie, there is a dinosaur's head depicted on the mountain in the back.

The raptors in the kitchen scene was filmed on Joseph Mazzello's ninth birthday. Due to a misunderstanding, Joseph ran into one of the raptors on one of the takes, and was injured.

(at around 1h 25 mins) Perhaps to increase the general sense of anxiety (if only subconsciously), the Triceratops mural behind Hammond as he eats ice cream in the visitors center also incorporates elements from "Guernica", Pablo Picasso's famous painting of the horrors of war.

Steven Spielberg wanted the dinosaurs to breathe in and out, pulsing visibly, and the eyes to dilate like on E.T. the Extra-Terrestrial (1982) because it made them more real, and was also scary to see.

Sets were constructed on five of Universal's largest soundstages and one enormous Warner Brothers stage. Because of the costs, money was saved by purposely not finishing some of the sets, like the entrance hall and restaurant of the Visitor's Center, making it look like the building is still under construction. The scaffoldings on these sets were not props but actual tools used by the film's construction crew.

Steven Spielberg studied the effects sequences on Terminator 2: Judgment Day (1991), The Abyss (1989), and Young Sherlock Holmes (1985) to help prep him for work on this movie.

When filming the kitchen scene, which was filled with reflective surfaces, Dean Cundey had to plan the illumination while using black cloths to hide the light reflections.

Shooting Grant rescuing Tim out of the tree involved a fifty-foot prop with hydraulic wheels.

In reality, Dilophosaurus actually measured around seven meters (twenty-three feet) long, and weighed close to five hundred kilograms (one thousand one hundred pounds). In addition to making it venomous, and adding a neck frill, Steven Spielberg also reduced the size of Dilophosaurus to .91 meters (three feet) tall, and one and a half meters (five feet) long, so viewers wouldn't confuse it with the Velociraptors.

Donald Gennaro makes a small appearance in 'Weird Al' Yankovic: Jurassic Park (1993) claymation music video. He is reading a newspaper in the bathroom, when the Tyrannosaurus Rex appears and eats him (then proceeds to drink a cup of tea and floss). In regards to the dinosaur eating the lawyer, the song includes the line "Well, I suppose that proves they're really not all bad."

This movie won all three Oscars for which it was nominated: Best Sound, Best Sound Effects Editing, and Best Visual Effects.

Scientists think that the position of the Velociraptors arms might be incorrect. Instead, the wrists of the Velociraptors would've been turned inward like the Velociraptors were constantly holding a basketball. This would've made it much more difficult for the raptors to open the door to the kitchen.

When a young Elijah Wood presented the Oscar for Best Visual Effects, a T-Rex emerged from behind him with the envelope.

For Film Review's 55th anniversary in 2005, it declared this movie one of the five most important in the magazine's lifetime.

When Nedry is stealing the dinosaur embryos, there is one labelled a Brontosaurus. Brontosaurus was not a real dinosaur, but one named by a paleontologist that had the wrong skull on his specimen. The correct skull for the animal was found by a different scientist, and it was then called the Apatosaurus.

Robin Wright was offered the role of Dr. Ellie Sattler.

The Triceratops is Grant's favorite dinosaur, and it was also Steven Spielberg's because "three horns are better than one".

Was followed by two sequels within ten years after its release. There were plans for a fourth movie, but they were immediately scrapped in late 2008, after the death of Michael Crichton. However, in 2012, they eventually did decide to set things into motion, and Jurassic World (2015) was finally released in 2015.

Jeff Goldblum was first interviewed for the role of Dr. Ian Malcolm after director Steven Spielberg abandoned the draft written by Malia Scotch Marmo, which had omitted Malcolm. Although they didn't use her draft, they were still considering leaving the character out, which Spielberg told Goldblum. Goldblum had read the book and advocated heavily for the character's inclusion.

Steven Spielberg was totally surprised by the storm Hurricane Iniki. He switched on the news on the morning of September 11th. "Like in a bad movie", the first shot of the news was a map of Hawaii with the hurricane. In a 2013 interview with Matt Lauer, Sam Neill said he was standing on the beach that day with Laura Dern. Laura asked, "do you think we're gonna be alright, Sam?" Sam responded: "I think we might die, Laura." She laughed.

Upon learning that he had been cast as Malcolm, Jeff Goldblum, who had read the novel to prepare, went out and bought the clothes his character would wear. He is described in the book as wearing all black, coming from Dallas (hence the cowboy boots) and, like a typical chaos theorist, behaving like a rock star, hence the leather jacket, sunglasses, and jewelry.

Much of the behavior seen in the movie is based on modern wild animals, since little is known of the actual behavior of dinosaurs.

Although his character is opposed to it, Jeff Goldblum thinks a dinosaur safari park is a cool idea.

As the story takes place on an island near Costa Rica, the filmmakers originally considered filming in Costa Rica. This idea was quickly abandoned when they realized that the Costa Rican government would not allow them to build roads to get to their filming locations.

BioSyn is InGen's genetics rival in the novel.

The Dilophosaurus model was made deliberately smaller than the real thing, so as not to confuse it with the Raptors. It was nicknamed "Spitter" by Stan Winston's team.

Although this movie managed to outperform E.T. the Extra-Terrestrial (1982), as the most successful movie worldwide in history, it did not top E.T.'s gross in North America.

Steven Spielberg knew as soon as his kids saw the model T. Rex they wouldn't want to go home, which is just the reaction he wanted. Michael Crichton also viewed the model, and was impressed.

(at around 1h 25 mins) In the shots of the gift shop, clearly visible, is a book titled "The Making of Jurassic Park" by Don Shay and Jody Duncan. An actual book with that title and those authors (but a different cover) was published; it was the official behind-the-scenes story of how this movie was made. Jody Duncan also wrote the making-of book for The Lost World: Jurassic Park (1997).

(at around 40 mins) When getting an update on a storm, Hammond says "Why didn't I build in Orlando?" The distributor, Universal Studios, has two theme parks there. One of them, Islands of Adventure, has a Jurassic Park themed area and rides. This line may also be a subtle reference to Disney World, as Crichton intended Hammond to be a darker vision of Walt Disney.

Steven Spielberg didn't want people to be constantly reminded that what they're seeing is CGI, but real, full-blooded dinosaurs, starting with the Brachiosaur scene, where Spielberg was keen on the dinosaur interacting with the background, and would offer suggestions to the animators on how to make it better. The second scene done in that same vein was the Gallimimus scene, which made use of twenty-five animated individual Gallimimuses. Geometric shapes represented them initially and were choreographed into the scene. Spielberg needed complete freedom to convey the energy of the scene, so he worked with Dennis Muren to shoot it, because he wanted to move the camera and not lock it down everytime a Gallimimus came into frame. The scene was shot gradually with Sam Neill, Joseph Mazzello, and Ariana Richards running through a field by themselves. A grid was placed over the ground as a frame to chart the movement of the camera by computer, using what looked like golf balls whenever an actor or actress looked somewhere. The dinosaurs were added later.

(at around 25 mins) The Mr. DNA film was created by Bob Kurtz. Steven Spielberg wanted one of those creaky instructional animations from school to deliver the exposition about dinosaurs being created to the audience. Kurtz feared Mr. DNA was too corny, and the audience wouldn't buy the dinosaurs, but Spielberg thought it should be a little corny. The Brontosaurus at the end of it is a tribute to Winsor McCay's Gertie the Dinosaur (1914), but most of it wound up on the cutting room floor. Kurtz created similar sequences in City Slickers (1991) and Honeymoon in Vegas (1992), as well as a singing cereal packet for Minority Report (2002), and a trailer for Casper (1995).

(at around 35 mins) Malcolm's speech to Hammond about the dangers of Jurassic Park are condensed from the novel: "Scientific power is like inherited wealth: attained without discipline. You read what others have done, and you take the next step. You can do it very young. You can make progress very fast. There is no discipline lasting many decades. There is no mastery: old scientists are ignored. There is no humility before nature. There is only a get-rich-quick, make-a-name-for-yourself-fast philosophy. Cheat, lie, falsify, it doesn't matter. Not to you, nor to your colleagues. No one will criticize you. No one has any standards." This may have been edited by the movie to make Malcolm seem less arrogant.

When scouting in Kauai, Steven Spielberg thought the jungle looked like broccoli. He wanted a division between the clearing and the tops of the trees for the first scene with the Brachiosaur. Initially, it was to appear behind some trees, but they obstructed it.

The Raptor hatching scene was envisioned with someone holding the egg at first.

A life-size T. Rex drawing on the wall of Stan Winston's studio helped create the real thing. The T. Rex was so enormous, they had to raise the roof to accommodate the sculpture.

(at around 1h 13 mins) The dilophosaurus' venom was originally to be pale green. However, the combination of studio set lights and artificial rain rendered it nearly invisible on film, so it had to be darkened.

(at around 2h 5 mins) When it says "A Steven Spielberg film" at the end of the movie, listen closely. You will hear the slightly modified five tones from Close Encounters of the Third Kind (1977).

The filmmakers and effects crew considered changing the Velociraptor's name back to Deinonychus, on which the creature was actually based. Ultimately, like Michael Crichton, they decided that velociraptor sounded cooler. All of their research, however, was based on deinonychus.

To showcase the movie's sound design, Steven Spielberg invested in the creation of DTS, a company specializing in digital surround sound formats, so it would allow audiences to "really hear the movie the way it was intended to be heard". George Lucas supervised the sound crew while Spielberg was in Poland working on Schindler's List (1993). The work was finished by the end of April. Sound designer Gary Rydstrom considered it a fun process, given the movie had all kinds of noises: animal sounds, rain, gunshots, vehicle crashes, scenes without music, et cetera. Spielberg took the weekends to fly from Poland to Paris, where he would meet Rydstrom to see the sound progress.

When the helicopter lands on the island (at around 17 mins), dummies were used instead of real passengers because of the riskiness of the descent at the location of Manawaiopuna Falls.

(at around 29 mins) In the egg-hatching scene, a newborn baby triceratops was originally supposed to come out of the egg, but it was changed to a velociraptor.

Steven Spielberg considered Richard Dreyfuss, who starred in his Jaws (1975) and Close Encounters of the Third Kind (1977), for the role of Dr. Alan Grant.

The first movie to use DTS (now Datasat) digital surround sound.

To study the movement of the Gallimimus herd, the digital artists were ordered to run along a stretch of road with some obstacles, their hands next to their chest.

This movie gave a much needed boost to Michael Crichton's flagging career. After the global success of this movie, Crichton became a hot commodity in Hollywood, with many of his novels adapted into movies.

(at around 1h 30 mins) The scene where they show an injured Malcolm laying spread-eagled on a table with his shirt wide open (after Grant said that Malcolm was right that life found a way for the dinosaurs to breed) became synonymous with the movie and into pop culture and even has its own brand new Funko Pop.

This movie had perhaps the most rigorous marketing campaign ever conducted for a movie, up to that point, costing up to $65 million, including licensing deals with 100 companies to market 1,000 products. Merchandise with the Jurassic Park name on it included toy dinosaurs, calendars, "Making-of" books, action figures, bread, yogurt, fast food, video games, a deal with McDonald's for "Dino-sized meals", a junior novelization, comic books, a Jurassic Park Discovery Centre at Islands of Adventure, shirts, et cetera. Although this led to a somewhat blasé reaction when the movie premiered, the marketing turned Jurassic Park into a box office phenomenon, and toppled E.T. the Extra-Terrestrial (1982), previously Steven Spielberg's most commercially successful movie. It's said the marketing cost more, and made more, than the movie did, setting a new record for tie-ins, over 1,000 individual deals that generated over $1 billion in revenue.

(at around 49 mins) Tim makes references about Robert Bakker and his dinosaur book. Bakker was a technical advisor on this movie, and was the inspiration for the character of Dr. Alan Grant in the original novel.

(at around 1h 35 mins) The scene where the T. Rex comes out of the bushes and eats the Gallimimus was shot on the island of Oahu at Kualoa Ranch. This was the only outdoor scene not filmed on Kauai, due to Hurricane Iniki.

Steven Spielberg's most expensive movie at that point in his career.

In Michael Crichton's novel, John Hammond proudly says (at around 42 mins) that the narrator on the pre-recorded park tour is Richard Kiley. Later, Kiley was hired to play himself in that role for the movie. Possibly the first instance of a celebrity appearing in a book, and then later cast as him or herself in the movie version. This feat was not repeated until 2009, when boxer Paolo Roberto played himself in the movie version of The Girl Who Played with Fire (2009). He too was already previously featured as a character in the book.

The T. Rex's visual acuity based on movement (which is true of most animals) was not entirely right in the movie. It still had an incredible sense of smell and would have sniffed out its prey if not for a sinus infection, in the movie allegedly. An aspect that was used in The Lost World: Jurassic Park (1997).

(at around 22 mins) As well as the Brachiosaurs when Grant and Ellie first arrive in Jurassic Park, the other dinosaurs they see in the distance are Parasaurolophus.

Jack Horner described the T. Rex model as "the closest I've ever been to a live dinosaur".

Kurt Russell turned down the role of Dr. Alan Grant, due to salary demands.

All of the raptors are kept in a small pen near the Visitor Center. However, things that Robert Muldoon says hints that the raptors weren't always kept in this pen, nor that it is their permanent place as he states; "Fifty, sixty miles per hour if they ever got out in the open. She's the reason we have to feed 'em like this. She had them all attacking the fences when the feeders came." - Muldoon. At a later moment, a computer screen shows that the electric fences fall off. The computer screen shows the position of a "Raptor Paddock". The enclosure in the movie is narrower than most other enclosures. The Paddock is surrounded by the other paddocks. In the nest scene, Alan Grant and the children discover a dinosaur nest at a tree trunk. Some fans think this scene took place in the Raptor Paddock, and that it is a raptor's nest. This can be highly supported by shape of the babies tracks leaving the nest.

The leaf Ellie examines is something she took en route, and it's in the trailer, but not the final movie.

Jack Horner's research is controversial, which is exactly why he found Jurassic Park, and its idea of reviving dinosaurs, especially a T. Rex, fascinating. But he is opposed to the idea of scientists reviving them.

Pre-production lasted for twenty-five months.

The roar of the Tyrannosaurus Rex has been used for most monsters ever since this movie's release, as it signifies a large animal's large lungs.

Brachiosaurus means "arm lizard" and was one of the largest animals ever weighing up to ninety tons. They were called sauropods. The Brachiosaur was one of the few dinosaurs in the movie that lived in the Jurassic period 200 million years ago, but it was the Triassic that launched the age of dinosaurs. Tim mentioned Brontosauruses which were used in the movie, which means "thunder lizard", and were smaller, about thirty to forty tons.

(at around 10 mins) On the walls inside Grant and Sattler's trailer are a couple of scientific skeletal reconstructions of raptors, according to how they had really been imagined in the beginning of the 1990s. Interestingly, these are actually the most accurate dinosaur reconstructions on the film, having been made by paleontologist and paleo-artist Gregory Paul, whose book (Predatory Dinosaurs of the World) Michael Crichton studied when writing the original Jurassic Park novel. One of the papers on the wall is in fact a page from Paul's book.

Anna Chlumsky and Christina Ricci auditioned for the role of Lex Murphy.

Compositing dinosaurs onto live-action scenes took up to an hour. Rendering them took from two to four hours per frame, but the T. Rex in the rain took up to six hours.

(at around 1h 30 mins) In an interview with IGN, Jeff Goldblum described how his iconic semi-supine pose came to be, he vaguely recalled director Steven Spielberg slyly asking him to unbutton and to rub oil on his chest.

The Gallimimus vocals were done with horses, male and female, because the females make interesting sounds when a male horse shows up like high pitched squealing. The stampede sound was running horses or cattle getting herded.

The first movie to cross the $400 and $500 million dollar marks at the international box office.

(at around 21 mins) Earlier in the film, Hammond mentions that "they clocked the T. rex going 32 miles per hour," so the car could easily outrun it. Computer simulations using the T. rex's skeletal structure have found that it probably only ran at a maximum of 11-18 mph and that its legs, in ratio to the rest of its body, were not large enough to propel it beyond 25 mph. It was Ian's leaning back in terror that stopped the car from accelerating at first, resulting in the close shave before the getaway. When Ian leans back, he knocks the gear shift lever loose which put the Jeep in neutral (at around 1h 21 mins). You can hear Muldoon shouting "Get off the stick! Bloody move!!" to Ian.

In the summer of 2020, with most movie theaters shut down due to the COVID-19 pandemic and new movies being withheld by the studios, Jurassic Park (1993) managed to top the box office again, playing in small drive-in venues that popped up to meet demand. The weekend of June 19th, it narrowly beat another Steven Spielberg film, Jaws (1975), for the top box office - but with less than $1 million in ticket sales.

The T. Rex model was the largest sculpture ever made by the Stan Winston studio.

Steven Spielberg and Michael Crichton first met over two decades earlier, when Spielberg gave Crichton a tour of Universal Studios during the production of The Andromeda Strain (1971).

The movie marked the climax of the "Dinosaur Renaissance", a groundbreaking scientific revolution that lasted from the 1960s until the early 1990s, during which dinosaurs went from being seen as sluggish, dimwitted, and cold-blooded reptiles, to the agile, intelligent, and warm-blooded animals depicted in this movie. It also presented a new kind of visual "design" of the dinosaurs to the public. Much of this can be traced back to the works of paleontologists John Ostrom (who first realized the uniqueness of "raptor" dinosaurs), Robert Bakker, Jack Horner (on whom the character of Dr. Alan Grant was based), and Gregory Paul. In fact, modern day paleontologists often jokingly call the 1990s and early 2000s the "Paulian Era", because the appearances of the dinosaurs in the movie and in virtually every other piece of work created at this time were based on reconstructions originally made by Greg Paul. Newer scientific findings have, however, proven much of these to be incorrect, which has lead to the coining of the term "shrink-wrapped dinosaurs", as many of Paul's reconstructions (and by extension, the Jurassic Park dinosaurs) look like dinosaur skeletons coated in muscle and skin, but virtually no other soft tissue.

There were two animatronic Tyrannosauruses built for filming. One was the full-body version, the other only consisted of a head, and was used for close-ups.

Steven Spielberg identified with Hammond's obsession with showmanship.

Michael Crichton was hired to adapt his novel for the big screen for five hundred thousand dollars, but David Koepp wrote the final draft, leaving out much of the novel's exposition and violence, as well as making a few character changes.

The second highest-grossing movie of the twentieth century (not adjusted for inflation), behind Titanic (1997).

Triceratops and Dilophosaurus are the only dinosaurs not portrayed in CGI.

(at around 1h 55 mins) Steven Spielberg liked the ending for having the dinosaur bone exhibit getting demolished by the real deal and took the irony further by having the T. rex behind a banner that read "When the Dinosaurs Ruled The Earth".

According to David Koepp, the famous, "Hold onto your butts!" catchphrase spoken by Samuel L. Jackson was actually inspired by Robert Zemeckis, when they were working on Death Becomes Her (1992), and he had the good sense to jot it down immediately and use it.

Steven Spielberg wanted all the top special effects people in the business to work on the movie as the design team, Stan Winston, Dennis Muren, Phil Tippett, and Michael Lantieri. They jumped at the chance.

(at around 20 mins) Jeff Goldblum claimed that his reaction to seeing a Brachiosaurus for the first time was captured in one take ("you crazy son-of-a-bitch, you did it"), with Steven Spielberg dictating to him off-camera what expression he wanted.

(at around 15 mins) When Malcolm says to Grant and Sattler on the helicopter, "so you two dig up dinosaur bones" to which Grant responds "try to" to which Malcolm laughs at was Jeff Goldblum's favorite scene filmed.

Paleontologist Rubén A. Rodríguez de la Rosa proposed some dinosaurs transmit venom in a similar way to venomous snakes. Scott Sampson of the Utah Museum of Natural History hypothesized that dinosaur bites could've been deadly due to large quantities of bacteria in their mouths (similar to Komodo dragons). However, in both theories, they'd be incapable of projecting the venom onto their prey.

Researchers from the Faculty of Life Sciences at The University of Manchester tried to harvest DNA from young sub-fossilized insects preserved in copal (the precursor to amber) to no avail, suggesting that the likelihood of finding ancient DNA in a specimen much older is much less likely.

The mosquito trapped in amber (copal) is an elephant mosquito (Toxorhynchites), the only mosquito that doesn't drink blood, they live on sugary substances like nectar from flowers and sap of plants; therefore, it couldn't contain any dinosaur DNA.

In a 2010 poll, Entertainment Weekly rated this movie the greatest Summer movie of the last twenty years.

Steven Spielberg managed to acquire the movie rights before the novel was even published for one and a half million dollars in 1990.

Both times Lex and Tim are left by an adult, by Gennaro when he leaves the Explorer, and by Grant at the Visitors Center, they come under attack from a dinosaur or dinosaurs.

Dinosaur supervisor Phil Tippett did the Brachiosaurus scenes first. They were difficult because of the new technology. He wanted flesh moving, so when the feet went down you saw tremors through the muscles. Dean Cundey made it appear like it was nibbling by attaching a cable to the top of the tree and pulled on it to get the branch to react and snap. The animators carefully coordinated the animation with that.

(at around 32 mins) Hammond describes Muldoon as an "alarmist". Michael Crichton was often alarmist about scientific discoveries, as mirrored in Muldoon and Malcolm's characters.

The third dinosaur scene with the cast was at the Raptor pen, where Steven Spielberg provided some of the vocalizations to motivate the actors.

(at around 32 mins) The scene where an entire steer is fed to the raptors, a steer was harnessed in a special cattle sling, hoisted up by a crane, then lowered into foliage. The steer is not shown being devoured, but the effect is created with sound effects. The steer filmed for this scene was actually very mellow as he had been prepped and rehearsed with it over a period of time prior to filming. The harness was the type normally used to move steer and was safe and secure.

Steven Spielberg wanted the movie to honor dinosaurs in a way that had never been seen before. He wanted the audience to believe what they were seeing.

William Hurt was offered the role of Dr. Grant, but he turned it down without reading the book or the script.

(at around 1h 55 mins) In one moment of the movie, one Velociraptor appears in head shot illuminated with a computer screen full of four letters repeated time and time again: "ACGT". These letters are the acronym for Adenine, Cytosine, Guanine, and Thymine, DNA's base pairs.

The AFI named this movie the 35th most thrilling movie of all time on June 13, 2001.

Ariana Richards regretted never getting to work with the Dilophosaurus or even see it during the shoot because it was a real surprise when watching the movie. She was glad she didn't get spat at though.

(at around 1h 30 mins) U.K. streaming service, sanctioned the construction of a dinosaur-sized Jeff Goldblum monument in his memorable semi-supine pose from this movie with his exposed chest in all of its glory, for the 25th Anniversary of the science fiction staple. Although the anniversary was officially on June 11, the sculpture was placed in front of the iconic Tower Bridge in London on Wednesday. Like the shot of the partly shirtless Goldblum, which is so peculiar because he looks so magnificent despite the fact his character had just broken his leg, the statue is too huge to fully absorb at a glance. Standing at over 9.8 feet tall, twenty-three feet long, and weighs three hundred thirty-one pounds. Bringing it to life took a substantial amount of man hours: two hundred fifty hours over six weeks.

Joseph Mazzello also had a playful relationship with the adult cast members, such as Jeff Goldblum, who'd entertain the kids by coming up with skits for them to perform during downtime. "The entire cast was so warm and friendly to us kids. You know, we never felt like outsiders. Or we never felt, like, condescended to. We felt like part of the gang," he said. "It was just a really just warm and sort of fun atmosphere whenever Jeff was around. It was awesome."

The animatronic raptors used in the movie were given the names Kim and Randy by the crew.

(at around 26 mins) The scene where Mr. DNA is discussing the creation of the dinosaurs has a list of genetic code that flies along the screen. This is not dinosaur DNA, but is also not random. The code belongs to a restriction enzyme which is a circle of DNA used by E. coli to defend itself against viruses. It was the first completely sequenced full section of DNA.

TIME Magazine and the Scholastic Dinosaur Encyclopedia mention that Steven Spielberg, in appreciation of inspiration and guidance from a number of paleontology experts, donated $25,000 to the Dinosaur Society for excavations in China. This gesture gave him the right to name a recently discovered type of ankylosaur "Jurassosaurus nedegoapeferima", the latter designation an acronym of the movie's leading actors Sam Neill, Laura Dern, Jeff Goldblum, Richard Attenborough, Bob Peck, Martin Ferrero, Ariana Richards and Joseph Mazzello. Paleontologist Dong Zhiming later on changed the first name to Tianchisaurus, which means 'heavenly pool lizard', after the Lake Tianchi site where he had found the skeleton.

Noriaki Yuasa, director of the early Gamera films, considered this the greatest monster film made because it was pure entertainment.

Cameron Thor has said he would happily reprise his role of Lewis Dodgson at any time, because it's the character for which he's most recognized. The character was included in the sequel novel, "The Lost World", but not in the film adaptation. The character of Dodgson is returning in Jurassic World: Dominion (2022), but without Thor, who is serving a 6-year prison sentence following his 2016 conviction of sexual misconduct with a 13-year-old girl. The role of Dodgson has been recast for Campbell Scott.

Although sickly in the movie, a Triceratops could, in reality, successfully battle a T. Rex.

A Jurassic Park tourist attraction was unveiled at Dorset's Dinosaur Museum. Also, there's a Jurassic Park log flume ride at Universal Studios in Los Angeles. All of the Universal Parks and Resorts include a theme ride associated with this movie. The first was Jurassic Park: The Ride on June 15, 1996, built after six years of development for one hundred ten million dollars. It was replicated for Universal Studios Japan, in 2001. Islands of Adventure in Orlando, Florida (a place Hammond wished he had built the real park), has an entire section dedicated to the movie that includes the main ride, christened "Jurassic Park River Adventure" and many smaller rides and attractions based on the film franchise. In Universal Studios Singapore, which opened in 2010, the Themed Zone named The Lost World consists mostly of Jurassic Park rides, such as the roller coaster Canopy Flyer and the river rapids Jurassic Park Rapids Adventure.

Stan Winston claimed the first T. Rex attack was the most amazing scene on which he had ever worked, at that point in his career.

In the Jurassic Park movies, the dinosaurs are shown waving their tails quite a bit. In reality, these tails would be rigid and used to balance the animal. Therefore, if the tails on large creatures like the T. Rex flailed everywhere like the movie, the T. Rex would run a much larger risk of losing balance.

The park software is written in Pascal. A program is clearly visible in one of the monitor close-ups on the UNIX system. The graphical interface recognized as a UNIX system was the experimental Silicon Graphics 3-D File System Navigator. The version number of the Silicon Graphics UNIX Operating System is 4.0.5 and is visible in one of the close-ups in the operating system's shell window (command program).

This movie visits four places within the first thirteen minutes. After that, it stays on Isla Nublar.

Phil Tippett recruited a team to supply more than fifty Go-Motion (a more refined version of stop-motion) shots.

Steven Spielberg left the editing for two weeks to start shooting Schindler's List (1993) in Poland.

In the special features for The Fly (1986), Jeff Goldblum revealed that he first met Martin Ferrero at the airport for their flight to Hawaii. Ferrero then suggested that it should be Malcolm who dies, and Gennaro who lives. This is, in fact, how it went in the novel. Malcolm ultimately dies of his injuries, and Gennaro; who is not present for the Tyrannosaur attack because he stayed behind with Ellie with the sick Steogsaurus/Triceratops; lives and helps Muldoon get the park running again, much of which was given to Ellie in the movie.

Steven Spielberg chose to cast Wayne Knight after seeing his acting performance in Basic Instinct (1992), saying, "I waited for the credits to roll and wrote his name down."

(at around 1h 50 mins) One of Joseph Mazzello's most intense moments of filming was during the famous kitchen scene, when Tim is being chased into a freezer. "It was a raptor on wheels that was to follow me, and I'm supposed to go left, and it's supposed to go to the right," he recalled. "We did a bunch of takes. And one time I went left and I sort of turned around to look up and see the raptor turning the same way as me. And its claw, which was metal, hit me in the head because I was that height. And I fell down. I was a little bit dazed. It also was my birthday. I turned 9 years old. And so Steven (Steven Spielberg) after checking that I was okay, said, 'I think this is the perfect time for this,' and had the entire crew sing happy birthday to me.

Michael Crichton's original idea for the screenplay was about a graduate student who re-creates a dinosaur. He continued to wrestle with his fascination with dinosaurs and cloning until he turned it into a novel. Steven Spielberg first learned of it in October 1989.

Dr. Alan Grant has at least two dinosaur models from the 1988 Carnegie Collection: The original green color Tyrannosaurus Rex, and the adult Apatosaurus.

There have been attempts made before and after the movie to locate preserved dinosaur DNA. Ten percent of the time, they were successful, but never a completely uncontaminated sample.

(at around 1h 55 mins) Later in the movie, as one of the Jeeps pulls up, right before they get out, the camera zooms in on the Jeep door. The Jurassic Park logo is on the door, but it is covered in mud so that the only words that can be read is "urass Park", perhaps a subtle joke about many of the characters getting hurt or killed in the movie.

In 2011, Martin Ferrero reprised his role of Donald Gennaro in a CollegeHumor parody of this movie.

The hatchling's egg was made of wax with a layer of Saran Wrap laid on top of it, and the hatchling was molded by Greg Figiel. The puppet was puppeteered by over seven people.

(at around 1h 14 mins) After Nedry is attacked by the Dilophosaurus we see the shaving cream can containing the dinosaur embryos he stole being buried in mud. This can is also present at the very end of the Jurassic Park ride where it is sitting on a rock next to a Dilophosaurus squirting water at riders the same way the animal squirted venom at Nedry.

(at around 54 mins) The shot of the wave crashing over the sea wall was actual footage of storm surge from Hurricane Iniki when it hit Kauai.

Dilophosaurus lived during the early Jurassic Period, before mosquitoes are currently confirmed by the fossil record to exist. If Jurassic Park was able to find any viable DNA specimens, there would have been very little to go on. This would mean that there would be more gaps than normal in the DNA sequence, subsequently filled by more frog DNA. This could explain why the Dilophosaurus are so different from their prehistoric counterparts, far more so than other dinosaurs.

Laura Dern got cast after Steven Spielberg saw her performance in Rambling Rose (1991).

Although this was one of the first movies to use CGI, it was pioneered (albeit in its infancy) on another Steven Spielberg movie, Close Encounters of the Third Kind (1977).

The Tyrannosaur paddock set was constructed on-location and as a studio set. The former was for the daytime scene in which the creature fails to appear, and the latter for its nighttime escape, in order to accommodate Stan Winston's robotic T. Rex. This set required a soundstage much bigger than Universal had to offer, so it was filmed at Warner Brothers Studio.

The amber mine where Gennaro meets Juanito is called "Mano de Dios", which in English means "Hand of God".

(at around 36 mins) Jeff Goldblum quoted his character's memorable line, when responding to a recently reshared 2015 article about scientists at Harvard and Yale attempting to recreate dinosaurs. "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should", Goldblum tweeted.

The release strategy was planned fifteen months before the studio had the chance to see a frame of the movie.

The global success of the movie created a worldwide interest in dinosaurs, and a sudden interest in museums.

Released into 3-D on April 5, 2013, for the movie's 20th Anniversary. Other countries saw the re-release over the following six months. This release also had a Burger King promotional tie-in. Many people felt the 3-D conversion didn't enhance the effects in any way, mainly because most of the dinosaur scenes are set at night, and shadows don't come out the screen very well the way the day scenes do. This re-release pushed the movie's total gross to one billion dollars, the seventeenth movie to do so. It now ranks as the fourteenth highest grossing movie worldwide, the sixteenth highest grossing movie in North America (unadjusted for inflation), and the highest grossing movie released by Universal Pictures and directed by Steven Spielberg. Spielberg claimed he had produced the movie with a "subconscious 3-D", since the movie has animals walking toward the cameras and some effects of foreground and background overlay. In 2011, he stated that this movie was the only movie he had made he had considered for a conversion, and once he saw the 3-D version of Titanic (1997), he really liked the new look of the movie, and he hired the same retrofitting company. Spielberg and Janusz Kaminski supervised the nine month process during the production of Lincoln (2012). Industrial Light & Magic contributed some elements and updated effects shots for a better visual enhancement.

Tyrannosaurus Rex means "tyrant lizard". The T. Rex was the last massive carnivorous dinosaur.

This movie was storyboarded before it was scripted.

In May 1990, Universal Pictures obtained galleys of Jurassic Park and wanted to purchase it on Steven Spielberg's behalf. Michael Crichton had written the book in two years. Of the four major studios bidding on it, Crichton was happiest with Spielberg's involvement, and less than a week later, Spielberg got the job of directing it.

Broke the opening weekend record that had been set by Batman Returns (1992). It broke opening records in several countries.

Sam Neill and Jeff Goldblum appeared in Thor: Ragnarok (2017).

Dr. Grant's discovery that dinosaurs move in herds is taken from Jack Horner's research. Horner owns a Deinonychus claw, similar to the Raptor claw Grant owns.

Raptors are close knit, smart, fast, and maneuverable in their choreography more than any dinosaur. They could manipulate things with their fingers, as shown in the movie where they learn to open a door.

One unused storyboard for Hammond's ultimately discarded death was that he was originally going to be killed by the velociraptors, John Hammond is in Jurassic Park's control room during the climax when the Raptors have broken out of their pen and have entered the Visitor Center. John Hammond, with an incubator of eggs he plans to take with him upon leaving the park to "save it", hears Lex screaming downstairs. He opens the door to the control room to help, but is greeted by a Raptor. Hammond falls backward, crashing on a tabletop model of Jurassic Park that is on display in the control room (which was to be very similar to the one we see in Jurassic World: Fallen Kingdom (2018)), as the Raptor digs its claws deep into his chest. The incubator shatters to the floor, breaking one of the eggs while another remains unharmed. Later on, Grant finds Hammond in the control room, barely alive, as he tells Grant that he always knew the "first batch of DNA was too unstable" and that he was looking forward to working with him at the park. He then dies as the two men are framed by the destroyed model of Jurassic Park. Then, the one unharmed egg from before cracks open, revealing an infant Triceratops. other versions of his death are of Hammond simply being left behind on the island, either by his choice or by accident. Some art and storyboards of this idea were done by Art Director John Bell, with a version of this scripted in Malia Scotch Marmo's screenplay that followed both Michael Crichton's and the one the tabletop Raptor death was from.

The Stan Winston Studio team responsible for the creation of the Dilophosaur animatronic analyzed frame by frame a documentary featuring an ostrich which they used to create the hopping gait of its animatronic. Initially, a cam operated mechanism was created for one of its legs to follow the gait of an ostrich before a different mechanism was chosen. This later mechanism were rods coming out of its feet going beneath the floor and operated by a puppeteer. Inspired by the Steadicam, Rick Galinson created the concept for its neck. Each spring in the neck and head were sprung differently with each spring being heavier from the head the to the body, providing realistic movements. This had mechanism had originally been proposed for the raptor, but Stan Winston Studio was not convinced that it would work on an animal that large, so the steady cam mechanism was transferred to the Dilophosaurus. After the mechanism was crated, Stan Winston was impressed by what Galinson had done and applied it to the animatronic of the Velociraptor's head and neck, scrapping an alternate design for the raptor animatronic. The animatronic had three interchangeable heads: the frill in a lowered position, mechanized to allow the frill to open, and lastly the frill open and able to rattle as well as the ability to spit. The frill itself was a sheet of latex rubber glued onto some support rods hooked to a pulley. When activated it rotate out and forward at the same time as it was coming off the animatronic Dilo's neck. Its ability to spit was a paintball mechanism with the spit itself being a mixture of methacyl and K-Y Jelly with some food coloring. Underneath the tongue of the third head were two holes for the tubing that would have high-pressure air pumped through them to allow the animatronic the ability to "spit". The rest of the body, such as the head, tail, and arms were radio controlled. Cable-actuated insert legs were also created to portray the Dilo's hop when it initially approaches Nedry. The hopping was created by the legs being suspended from stage catwalks on bungee cords.

Mark 'Crash' McCreery designed the Velociraptor for the film. He created concepts of three life stages of the raptor: hatchling, juvenile, and adult, the juvenile which was never seen in the film, but was originally going to be included. McCreery began drawing the Velociraptor after his first two drawings of T. Rex when the film was trying to get greenlighted. Two of his drawings were created in 1991 and like with Mark Hallett's drawings, a trait in many of McCreery's concepts was a different head design from that of the Velociraptor on screen. Some design choices were suggested and/or considered of the Velociraptor in the film, but were never used. Phil Tippett once created go motion animatics of the raptors in the kitchen that featured them having forked tongues that they would flick out of its mouth like that of snake or monitor lizard as an allusion to the cross-referencing with genetic engineering used to create the dinosaurs. This idea was scrapped as paleontological consultant Jack Horner disagreed with it saying "No, can't do that, that's a lizard, dinosaurs aren't lizards they're birds."

Steven Spielberg wanted the Velociraptors to have forked tongues. According to Jack Horner he had to convince Spielberg to not give the velociraptors a snake-like aesthetic. "Originally Steven wanted them to walk in flicking their forked tongues," Horner said. "I said, 'No, no you cannot do that.'" Giving the raptors a forked tongue would have been scientifically inaccurate, since these dinosaurs were more closely related to birds than snakes. Spielberg isn't wholly to blame for wanting to give his raptors an unscientific tongue: In the "Jurassic Park" book upon which the movie is based, author Michael Crichton describes a Tyrannosaurus rex as having a forked tongue. Crichton writes of the T. rex: "With a low growl, the jaws slowly opened, and the tongue snaked out. It was thick and blue-black, with a little forked indentation at the tip. It was 4 feet long, and easily reached back to the far wall of the recess." But realistically, it's unlikely that the T. rex or velociraptor - or any dinosaur, for that matter - had a forked tongue the way modern-day snakes do.

Scientific advisor Jack Horner was such a strong advocate for dinosaurs being portrayed as bird-like that he even suggested that they should have brightly colored feathers. Spielberg won that argument because he believed "Technicolor feathered dinosaurs are not going to scare anyone." In later years however, fossils would prove many dinosaurs had feathers which were probably colorful. Raptors in real life would have looked barely different from birds, having full body feathery coats, with display feathers on their wings and tails that some smaller species used for gliding or flight. These feathers also made the animals more durable and agile. Ironically, while the raptors in Michael Chrichton's Jurassic Park novel had no feathers, they were still described as colorful, which was later adapted into the film's sequels.

Another iconic moment in the film sees Dr. Grant, Dr. Sattler, Ian Malcolm and assorted park employees attempting to treat a Triceratops with a bad stomach. They check it over, inspect its eyes, and Sam Neil even takes a moment to appreciate the miraculous beauty of the creature. But in a decision that probably went down incredibly badly with the people who designed the creatures, the Triceratops was originally bright and colourful. Purples, greens, yellows, its hide was one of the most visually stunning things in the entire film, until Effects Coordinator Stan Winston took one look at it, decided it didn't match its surroundings well enough, and covered it in mud.

Sam Neill struggled to affect an American accent for his role. Halfway through the first day of filming, Spielberg told him to forget it and just talk with his regular voice. Two days later, he asked him to "go halfway" between the two voices.

In anticipation of its Blu-ray release, Jurassic Park had a digital print released into U.K. cinemas on September 23, 2011. It wound up grossing £245,422 from two hundred seventy-six cinemas, finishing at eleventh on the weekend box-office charts.

Made its VHS and LaserDisc debut on October 4, 1994. With seventeen million units sold in both formats, it's the fifth best-selling VHS tape ever. It was released on DVD on October 10, 2000. It was the thirteenth best-selling DVD of the year, with nine hundred ten thousand units sold. In 2012, this movie was among twenty-five movies Universal Pictures picked for a box set that celebrated the studio's 100th Anniversary, as well as in Blu-ray, with an augmented reality cover. The following year, the 20th Anniversary 3-D conversion was issued on Blu-ray 3-D.

Steven Spielberg identified with John Hammond, seeing strong parallels between Hammond's vision for the park and his own work as a filmmaker. To this end, Hammond was made a more sympathetic character. To show the parallels to filmmaking, Spielberg cast fellow filmmaker Sir Richard Attenborough, which acknowledges the past and predicts the future. Spielberg lost the Best Picture and Best Director awards to him when E.T. the Extra-Terrestrial (1982) lost to Gandhi (1982). Spielberg's subsequent film, Schindler's List (1993), won both Oscars, and both starred Sir Ben Kingsley.

Cameron Thor had previously worked with director Steven Spielberg on Hook (1991), and initially auditioned for the role of Malcolm before trying out for the role of Dodgson. Thor said about casting, "It just said 'shaving-cream can' in the script, so I spent endless time in a drug store to find the most photogenic. I went with Barbasol, which ended up in the movie. I was so broke that I took the can home after the audition to use it".

(at around 1h 3 mins) When Gennaro runs to the toilet to hide from the T-Rex, he passes a sign which says "No Feeding, Flash Photography or Yelling"; the group does a form of all three in the moments leading up to the attack.

The Gallimimus stampede took place in a pasture. The crew came across a herd of cows and jokingly offered them jobs, offering to dress them up in latex as dinosaurs. Sadly, they all ran away.

This movie was completed on May 28, 1993, and released into theaters on June 11, 1993, but it premiered two days earlier at the National Building Museum in Washington, D.C., in support of two children's charities. Its nationwide release was in two thousand four hundred four locations on an estimated three thousand four hundred screens, with an international three thousand four hundred prints. Following release, a travelling exhibition called "The Dinosaurs of Jurassic Park" began, showcasing dinosaur skeletons and props from the movie.

Stan Winston, enthusiastic about the new technology pioneered by this movie, joined with IBM and James Cameron to form a new visual effects company, Digital Domain.

Some on the crew were worried that the computers would replace them, but instead it created more work for them.

Universal's Stage 24 became the industrial size kitchen set. Stan Winston's team manipulated every moving part of the full size Raptors, while Ariana Richards and Joseph Mazzello cowered in a corner.

Costa Rica was dismissed as a location because of Steven Spielberg's concerns about infrastructure and accessibility. He chose Kauai as a location because he had worked there before.

Michael Crichton was encouraged to write the novel after he took the idea about dinosaur cloning to some scientists who saw the plausibility in it. Crichton told Steven Spielberg the idea and he loved it, so Spielberg coaxed the rest of the story out of him. Spielberg then storyboarded the book (something he had never done before), with scenes he wanted to carry over to the movie.

Principal photography finished twelve days ahead of schedule, and on budget.

Laura Linney auditioned for the role of Ellie Sattler.

Much of the dinosaur behavior in the movie derived from information gleaned at digs in Montana, like the one in the movie, America's biggest dinosaur graveyard.

Nicole Kidman, Heather Graham, Lisa Rinna, Renée Zellweger, Melanie Griffith, Amanda Plummer, Kim Raver, and Mariska Hargitay were among those considered for the role of Dr. Ellie Sattler.

(at around 43 mins) The computer in the back of the computer room with the many (65536) red LEDs is a real computer: The Connection Machine CM-5 made by Thinking Machines. It contained many SPARC 2 RISC processors and the LEDs were added to make the machine more aesthetically pleasing than their previous models. Unfortunately, it was not actually a very good supercomputer and the company failed not long afterward. The comment about networking eight connection machines is pretty superfluous as they were meant to be used like this. The bigger problem was writing programs that efficiently mapped onto the data parallel architecture.

Jodie Foster, Sigourney Weaver, Michelle Pfeiffer, Ally Sheedy, Geena Davis, Daryl Hannah, Jennifer Grey, Kelly McGillis, Jamie Lee Curtis, Julia Roberts, Linda Hamilton, Sarah Jessica Parker, Bridget Fonda, Joan Cusack, and Debra Winger were all considered for the role of Ellie.

Jack Horner supervised all of the dinosaur designs, to get them as close to the real thing as possible.

(at around 1h 55 mins) When Lex nearly fell through the ceiling, the stunt girl looked up at the camera and Ariana Richards' face had to be superimposed, something not possible before the advent of CGI. It's considered one of the movie's most thrilling visuals.

The movie's logo and promotional image were in place before filming began.

Ray Arnold (Samuel L. Jackson) always has a cigarette between his lips, or between his fingers, every time he is seen in the movie. In the scene where he and Muldoon tell Hammond that the tour should be halted due to the storm, he is not smoking a cigarette, but has one lit nearby, hence the small cloud of smoke behind him. Him being a chain smoker was carried over from the novel.

For the hatchling vocalizations, Gary Rydstrom aimed to find a baby animal that had raspy vocalizations as the adults would make similar sounds. Rydstrom and his team recorded various baby animals including those of owls and foxes for the newly born raptor. The baby owl sounds were used for the baby's vocals upon Dr. Grant discovering its identity.

(at around 1h 7 mins) While it is unclear whether he soiled his underwear upon experiencing the T-Rex knocking the toilet down around him, it is clear that Gennaro only ran to the toilet to hide from the dinosaur. In several shots, you can see that he is still wearing his khaki shorts when the T-Rex finds and eats him. A scene similar to this appeared in the book, though the unfortunate victim was Ed Regis, who does not appear in the film. Ed Regis is present during the main road attack in the book, and like Gennaro, he abandons the children upon seeing the T-Rex. The book makes clear that Regis wets himself. The film shows a toilet nearby the road instead, which Gennaro runs to.

Like other tyrannosaurids, Tyrannosaurus had very short arms with only two fingers. Despite the limbs' size, each were able to bench-press about 400 pounds. Although these were probably nearly useless while hunting, its jaws were not: Tyrannosaurus has an enormous skull armed with teeth the size of bananas. Unlike the teeth of most theropods, the teeth of tyrannosaurids are very thick and capable of crushing bones and with a bite force of a minimum 4 tons of force and probably more, crushing bone, ripping flesh, and bursting blood vessels of the victim. The skull and neck bones show that T. rex had the largest neck muscles of any meat-eating dinosaur. It probably used its strong neck to twist and pull off big chunks of meat that it grasped with its jaws while supporting the huge head. Tyrannosaurus could bite with extremely strong force - one fossilized skeleton shows that it crushed and swallowed the bones of a smaller plant-eating dinosaur while another shows a Tyrannosaurus coprolite with the crushed frill of a Triceratops. Additionally, in Jurassic World: Alive, the Generation 2 Tyrannosaurus is referred to as Tyrannosaurus magnus, which scientists have considered a separate genus, Zhuchengtyrannus

Originally, the hatchery was to feature the infant Velociraptor based on the novel that would climb up Tim Murphy's arm and a hatchling Triceratops that would be portrayed by a simple finger puppet poking its head out of its egg. But the infant raptor would be scrapped and the Triceratops hatchling would become a raptor hatchling instead. Furthermore, the finger puppet approach was scrapped when director Steven Spielberg wanted the hatchling to crawl out of its shell. So Stan Winston Studio initially decided that the hatchling would be portrayed with cables with said cables being digitally removed in post-production until Richard J. Landon volunteered to design the animatronic. Landon mechanized the animatronic internally which was a difficult task for him.

The rippled water effect during the Tyrannosaurus Rex's approach is one of the most iconic shots in Jurassic Park and it's also one that drove members of the crew totally batty. Steven Spielberg was inspired to include the effect when he noticed his rear view mirror shaking while listening to Earth Wind And Fire in his car, but the filmmakers he assigned to make it happen for the movie were baffled. Michael Lantieri, who worked on Special Dinosaur Effects for the film, finally figured it out when playing his guitar, discovering that a particular note/frequency did the trick.

Jeff Goldblum recalled sitting and eating popcorn with Princess Diana who he called a "spectacular lady", at a special screening of the movie at the London's Natural History Museum.

The Dilophosaurus was made smaller than an actual one to differentiate it from the Raptors and to not have it compete with the T. Rex. But by making it smaller it fit the story, at first you don't take it seriously, but then you see how dangerous it is.

Velociraptor also means "quick plunderer". Their level of intelligence in this movie is equivalent to a chimpanzee with similar grasping hands.

The largest puppet in the movie, without hydraulics, was the Brachiosaur's upper neck and head.

It is the first movie to be dubbed in Hindi.

The 3D re-release of Jurassic Park opened at fourth place at the US box office.

Birds are a Velociraptor's closest living relative. The knowledge that dinosaurs are related to birds dates back to 1868, with similar ankles and tails, wrists and claws. Birds are the real way to bring a dinosaur back to life, with emus being the nearest thing there is to a dinosaur today, with the way they walk. Birds are a descendant of dinosaurs and chickens may lead to the creation of a dinosaur someday, but not a full-blooded one. It could also extend to other extinct animals and new fuels.

Michael Keaton, Bruce Campbell, Johnny Depp, Ted Danson, Steve Guttenberg, and Michael J. Fox were screentested for the part of Malcolm.

Steven Spielberg wouldn't have made the movie if he felt he couldn't get away with it, or shared a personal connection with it. Notions he has on all of his movies.

Since the Gallimimuses were precursors to birds, they had sophisticated flocking mechanisms; the parents keep the smaller ones in the middle of the group for protection. Details like that enhanced the scene subliminally.

In the 5th edition of 1001 Movies You Must See Before You Die, this movie is listed.

Juliette Binoche was offered the role of Dr. Ellie Sattler, but turned it down in order to make Three Colors: Blue (1993) with Krzysztof Kieslowski.

According to Daan Sandee (Thinking Machines Corp), the CM-5 super computer, used in the control room, was one of only two ever built to that size (1024 nodes). The other machine was at Los Alamos. The machine used in the movie, was sold in smaller segments after the scenes were complete. Mirrors were used to make it seem like more CM-5s were present.

Steven Spielberg needed miniature photography for any wide angle, or full-length dinosaur shots.

Attributed with changing the way movies were made in the future, after utilizing the best technology Industrial Light & Magic had available. ILM wanted the dinosaurs to move naturally, so they studied animal behavior, movements, and body language of elephants, alligators, ostriches, and lions. The graphic designers received special training, including movement lessons, to capture dinosaur behavioral nuances.

For the filming of Nedry's demise, a trench was built on the set for the path the Dilophosaurus would take as well as so that Shane Mahan could support and puppeteer the Dilo's legs while a crane above supported its body and the rest of the team responsible for its creation radio-controlled the other body parts of the animatronic upstairs. Because of the copious amount of water that was to be on the set during shooting, the soundstage used in the filming of the scene had a water tank underneath the set and was supposed to drain into the Los Angeles River, but the drainage system did not function well. This caused water to overflow into the puppeteering area, which lead to Mahan being given a riser to stand on just to get at least some of the water off of him, but the water level only got higher. The roaring of the water made it difficult to hear out of his headset making him unable to hear the film crew, which made him rely on video monitor stacked onto some Snapple boxes. But water got so high that this monitor floated away from Mahan and was rising to his chest. However, this was toward the end of filming and filming of the scene was filmed without Mahan drowning. Director Steven Spielberg thought that the Dilophosaurus was going to be the easiest practical dinosaur to film in Jurassic Park, but was disappointed by the problems that occurred when filming of the scene. The Dilophosaurus and Triceratops are the only dinosaurs to appear in Jurassic Park that did not use CGI, only using animatronics.

According to Mark Hallett, Steven Spielberg once considered during early development outfitting some of the chickens he owned with prosthetic heads, arms, and tails then letting them go berserk on scaled-down stage sets to the portray the raptors until the computer animation was perfected, but he was later convinced by those close to him to discard this idea. The idea for a bodysuit came independently from Stan Winston Studio when they were observing early storyboards. There was originally going to only be one full bodysuit to be made for the film though this soon became two suits. Each suit required the puppeteer to get into a skiing stance when entering before they were then zipped inside the suit using a zipper located in the back. To allow the puppeteer to see inside the suit, there were several small slits located in the neck where the person's head would be as well as a small TV monitor that was also fixed inside the bodysuit. Furthermore, due to the design of the suit being air-tight, an airline had to be fed up one of its' legs. Despite the original plan to design the suits without cable controlled mechanisms, instead using servos and radio-control, but cables were added to streamline the suit. The final suit featured radio-controlled eyes and the arms was half radio-controlled and half-cable controlled, the cables for the arms running down one of the legs of the suit. Furthermore, the tail was also mechanized and the wearer was able to move the head by two rods located inside the neck. John Rosengrant and Mark 'Crash' McCreery were selected to perform in the Velociraptor suits. Stan Winston hired a trainer to give the two men back exercises due to the position that they would be in during filming. Both suits saw usage in the famous Kitchen Scene, particularly when the first raptor to enter the kitchen calls for her subordinate. Rosengrant also used a raptor suit in the scene where Muldoon is killed.

Speaking on stage at a London screening, screenwriter David Koepp said of working on the Steven Spielberg-directed film: 'The problem I encountered, and I still encounter today when I work with Steven, is his movies are so influential, you have a tendency to create something you think he'll like. 'I kind of wanted to just type for him. You have to let that go. He doesn't need acolytes, he needs collaborators. The opening scene in my first draft was at a hospital in Costa Rica where somebody's flown in on a helicopter and said it's a terrible construction accident. 'I wrote a really good scene where this ER doctor looks at this guy, a person's who's been ripped to shreds and says "this is not a construction accident" 'He said "I love your opening I can't do it though, because I feel like I already did it." I said "what? When?" He said "yeah, it's in Jaws" I said "Oh yeah, right! I love that!"' 'That's a peril. You've got to write stuff you think is great, then he brings his stuff to it, rather than you trying to think ahead and write what you think he would want.'

Steven Spielberg had originally expected that he would have to lock down his camera during the gallimimus stampede. ILM animators, however, told him that a moving shot would actually be better, as it would help conceal the difficulty they were having to make the animals' feet seem to interact with the ground.

Michael Crichton spent years working on the story, trying to convince himself the premise was not so unlikely. He had to do a lot of research before he could.

Several scenes are taken straight out of the novel, but have the species of the dinosaur changed. In the novel, the visitors see an Apatosaurus, not a Brachiosaur, upon their arrival. The sick animal they encounter during the tour is a Stegosaurus, rather than a Triceratops. Grant and the children are caught up in a herd of Hadrosaurs, rather than Gallimimuses. While the Velociraptors are used in both the novel and the movie, their behavior is in fact more consistent with Deinonychus.

The trailer was narrated by Nick Tate.

Jeff Goldblum's line, "That is one big pile of shit," wasn't scripted.

Steven Spielberg considered hiring Bob Gurr to do the full-size dinosaurs because he was impressed with his apes in the "Kongfrontation" ride at Universal Studios.

The T. Rex was named "Roberta" in the storyboards by Phil Tippett, but many fans have accepted "Rexy" as her name. As of 2004, this animal was officially dubbed "Rexy" by her caretakers. This name is derived from the Latin rex, meaning "king," which is the specific epithet of Tyrannosaurus rex; it is modified into an English diminutive form as a sign of affection. This is a reference to her unofficial nickname in the novel, "Rexie." She is seldom referred to by InGen employees by this name, with the last confirmed use in 2004. Instead, she is typically referred to as "the tyrannosaur" or "the T. rex," though this risks confusion with InGen's other Tyrannosaurus rex specimens. During production of the film Jurassic Park, some material refers to her as "Roberta," though this name has never been used directly within the film canon. Similarly, she is given the nickname "Gulper" in one of the early toy lines, but this name has never been used in the film canon. Rexy was a popular nickname given by the fandom; it was suggested to be official in the mobile game Jurassic World: The Game and confirmed in The Evolution of Claire, which released on June 26, 2018. The production nickname "Roberta" has become increasingly popular among older members of the fandom as a response to the more popular "Rexy" being confirmed as official. To avoid causing distress to these more sensitive members of the fandom, Jurassic-Pedia has opted not to use the tyrannosaur's official canon name.

Steven Spielberg supervised the post-production on this movie concurrently with the filming of Schindler's List (1993).

Isla Nublar is Research Team 93, according to Jurassic Park merchandise. This movie was one of the most merchandised movies of 1993.

Phil Tippett created dinosaur miniatures, while Stan Winston provided full size robots. Michael Lantieri supervised interactions between actors, actresses, and the sets. Dennis Muren led Industrial Light & Magic with combining these elements on film in post-production.

The cast first interacted with Stan Winston's Triceratops, and it was important to Steven Spielberg that the movie succeeded from the first day of shooting, and after that scene, he knew they had. Winston felt that was a good scene into which to ease the crew, before they moved onto tougher stuff.

Joseph Mazzello's favorite scenes included "anything that involved climbing." "I really had no fear of heights as a kid," he revealed climbing on top of the electric fence was the funniest.

In 1937, Pablo Picasso created "Guernica", an oil painting that's still, to this day, considered to be one of the most moving and powerful anti-war paintings in history. Depicting the horrendous ariel bombing of the Spanish town of the same name, its ability to invoke horror and anxiety is undisputed in that art world. Wanting to recreate a slice of said horror and anxiety, Spielberg commissioned a special Dinosaur-themed reworking of the painting to be displayed in the visitor's centre. It can briefly be seen behind John Hammond later in the film

Although composed by John Williams, his score for this movie is not often counted among Williams' more famous movie scores. In 2013, for the 20th Anniversary of the movie, Williams released an album that restored fourteen minutes of music, cut from the original movie.

During the early stages, Go-Motion was considered to animate all the dinosaurs, except for the Gallimimus herd, where Dennis Muren insisted that be done with the then emergent CGI.

(at around 1h 30 mins) Lysine is an amino acid, one of the 'building blocks' of protein. Specifically, it is one of nine 'essential' amino acids that cannot be manufactured by the body and must be consumed in food. Sources of lysine include eggs, meat, soy, milk, Parmesan cheese, fish, and most grains and legumes. The lysine contingency plan called for withholding lysine from the dinosaurs' diets in order to kill them, if necessary. It was included in the construction of the animals' DNA so they could only survive with the diets provided in the park, i.e., they could not survive off the island. However, death by lack of lysine would take a long time, several weeks and even longer for the meat eaters since digestion of meat produces lysine. Hammond was against using the plan for the obvious reason... he didn't want to kill off all the dinosaurs, lose his investment, and be forced to start all over again. It might also be said that he felt a small compassion for his creations (which is why he screamed at Grant over the phone when he heard him shooting at the Raptors). While he certainly felt an attachment to the animals a more plausible explanation of his decision can be ascertained by his exclamation to John Arnold that 'people are dying!' Arnold was adamant he didn't want to be responsible for rebooting the park systems as they may not have come back on at all and seemed more in favour of Muldoon's suggestion to use the lysine contingency. However this would have taken too long to come into effect whereas 'theoretically' rebooting the system would have given them almost immediate control.

Steven Spielberg lost the Oscar for Best Director to Sir Richard Attenborough, when Spielberg's E.T. the Extra-Terrestrial (1982) lost to Attenborough's Gandhi (1982). In this movie, Spielberg got to direct Attenborough, but he is not the only one associated with Gandhi (1982) that Spielberg has directed in his career: Amrish Puri and Roshan Seth in Indiana Jones and the Temple of Doom (1984); Sir Ben Kingsley in Schindler's List (1993); Sir Nigel Hawthorne in Amistad (1997); Martin Sheen in Catch Me If You Can (2002), and Daniel Day-Lewis in Lincoln (2012).

Dinosaur experts Jack Horner and Robert Bakker were consulted before making the movie, and both were name-checked in the novel as well.

Bob Hoskins and Jeffrey Jones were considered for the role of Muldoon.

Dennis Quaid, Kevin Costner, Mel Gibson, and Robin Williams were considered for the role of Alan Grant.

Shooting on Kauai was completed by mid September, 1992 and then the crew shot the first scene with Grant and Ellie in the Mojave desert in two days. The rest of the movie was shot on soundstages, like the Genetics lab, the Visitors Centre and the T. Rex paddock. The first T. Rex attack gave the crew more control being shot on a soundstage, with CGI and animatronics interacting with the cast, and the set, and real-life, while being controlled off-screen.

(at around 28 mins) A Mitsubishi Movemaster RV-M2 is shown turning, moving and holding the eggs in place when they hatch (baby velociraptor).

According to one production photo, Steven Spielberg showed up on the set of the film's ending wearing a Letterman jacket with Tiny Toon Adventures (1990) on the left shoulder. He was the executive producer of that show and produced it with Warner Bros and Amblin entertainment.

New analysis of raptor teeth, published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, shows that raptorial dinosaurs likely did not hunt in big, coordinated packs like dogs. Recently, the scientists at the University of Wisconsin Oshkosh in the US has proposed a different model for behaviour in raptors that is thought to be more like Komodo dragons, in which individuals may attack the same animal but cooperation is limited. "Raptorial dinosaurs often are shown as hunting in packs similar to wolves. The evidence for this behaviour, however, is not altogether convincing. Since we can't watch these dinosaurs hunt in person, we must use indirect methods to determine their behaviour in life," said study researcher Joseph Frederickson. "Though widely accepted, evidence for the pack-hunting dinosaur proposed by the late famed Yale University paleontologist John Ostrom is relatively weak," Frederickson added. "The problem with this idea is that living dinosaurs (birds) and their relatives (crocodilians) do not usually hunt in groups and rarely ever hunt prey larger than themselves," he explained. Recently, the researchers have proposed a different model for behaviour in raptors that are thought to be more like Komodo dragons or crocodiles, in which individuals may attack the same animal but cooperation is limited. "We proposed in this study that there is a correlation between pack hunting and the diet of animals as they grow," Frederickson said. In Komodo dragons, babies are at risk of being eaten by adults, so they take refuge in trees, where they find a wealth of food unavailable to their larger ground-dwelling parents. Animals that hunt in packs do not generally show this dietary diversity. "If we can look at the diet of young raptors versus old raptors, we can come up with a hypothesis for whether they hunted in groups," Frederickson said. To do this, the research team considered the chemistry of teeth from the raptor Deinonychus, which lived in North America during the Cretaceous Period about 115 to 108 million years ago. "Stable isotopes of carbon and oxygen were used to get an idea of diet and water sources for these animals. We also looked at a crocodilian and a herbivorous dinosaur from the same geologic formation," he said. They found that the Cretaceous crocodilians, like modern species, show a difference in diet between the smallest and largest teeth, indicating a distinct transition in the diet as they grew. "This is what we would expect for an animal where the parents do not provide food for their young," Frederickson said. "We also see the same pattern in the raptors, where the smallest teeth and the large teeth do not have the same average carbon isotope values, indicating they were eating different foods," he added. "This means the young were not being fed by the adults, which is why we believe Jurassic Park was wrong about raptor behaviour," the researcher noted.

When Steven Spielberg enrolled at California State, Long Beach to earn his BA more than 30 years after dropping out, he was given three course credits in paleontology for making the film. He also submitted Schindler's List as his final project for his Advanced Filmmaking Class.

The bite force of a T-Rex was estimated to be around 8,000 lbs., They found the bite force of Deinonychus to be between 4,100 and 8,200 newtons, greater than living carnivorous mammals including the hyena, and equivalent to a similarly sized alligator. a velociraptors bite force was estimated to be around 1,000 lb per sq in.

One of the canes used by Richard Attenborough (with the mosquito encased in amber) is on display at the Hollywood Casino in Tunica, Mississippi.

Laura Dern previously auditioned to play Jeff Goldblum's love interest in The Fly (1986).

Laura Dern reaction to seeing the velociraptor in the maintenance shed was genuine. It was the first time she actually saw it, so the fear on her face is not acting it's actually real.

The first time dinosaurs have been depicted with CGI effects on film. Although CGI has moved on since, this movie is still considered to hold its own as one of the most thrilling in the field.

The roar of the T. Rex was performed by a male walrus.

Clint Eastwood and Marlon Brando were considered for the part of Hammond.

Go-Motion was used to see how the dinosaurs moved, but Steven Spielberg was very keen on the effects lacking any Go-Motion jerkiness; while his children bought into the early animations, he didn't.

(at around 1h 50 mins) When the SPAS-12 jams it appears to be an extractor malfunction, resulting in a shell in the breech holding back a loaded round from being chambered, commonly known as a "stovepipe". Such a jam is relatively straightforward to clear in reality, however it's likely Grant might not be familiar enough with firearms to know how to do so. The shells used in this scene are most likely dummy rounds given how fragile they appear.

Laura Dern's mother Diane Ladd also starred in a dinosaur film released in 1993. She played Dr. Jane Tiptree in Carnosaur (1993).

Malia Scotch Marmo did some re-writes on the final script, but remains uncredited.

The only movie in the franchise that doesn't show a dinosaur (or any other prehistoric reptile) in the final shot. The Lost World: Jurassic Park (1997) and Jurassic Park III (2001) had Pteranodons, Jurassic World (2015) had the famous T. Rex, and Jurassic World: Fallen Kingdom (2018) had Blue the raptor. However, the shot of the pelicans is similar to the shots of Pteranodons in the third film.

In the first half of the film, with the exception of the Brachiosaur, the dinosaurs are all below the characters' eye level, symbolizing their illusory control over the animals. In the second half, with the exception of the Dilophosaur, the dinosaurs are always above them or in the upper half of the frame. Movement from the top to bottom half of the frame indicates a descent into danger, while upward movement represents escape.

Production moved to Red Rock Canyon State Park in Cantil, California, chosen for its similarities to a Montana dinosaur dig, where Sam Neill and Laura Dern filmed their first scene. They were coached by Jack Horner, the premier paleontologist and curator of paleontology at Bozeman, Montana's Museum of the Rockies.

Phil Tippett acted as a consultant on dinosaur anatomy on the movie.

Briefly during the reboot sequence, a schematic of the Visitor Center building could be seen. This, however, was not entirely accurate. It would seem that the blueprints input in the computer were not the most up to date and were lacking in several key facilities.

While there were up to 15 dinosaur embryos stolen by Dennis which translates to Ingen having the embryos for 15 different dinosaur species. However, at the time of the Isla Nublar incident, There were only 7 dinosaurs that currently lived on the island. This included Brachiosaurus, Parasaurolophus, Triceratops, Tyrannosaurus Rex, Dilophosaurus, Gallimimus and Velociraptor. More were planned but never happened due to the park being abandoned.

Early artwork of selected scenes from the novel drew Dr. Grant to resemble Harrison Ford. Sam Neill had once been considered for Ford's role of Indiana Jones, and Ford was considered for one of the leads in The Hunt for Red October (1990), in which Neill also appears.

Mike Trcic expressed disappointment with the popularity of the T-rex design in an interview with Shannon Shea (who worked with Trcic on Jurassic Park). In the interview, he said regarding how popular the design had become, "Whenever I search Google images for a Tyrannosaurus Rex [sic], most of the art I see is based on the original JP Rex. It's a shame that people just accept that somehow it is what a T-Rex [sic] looked like. It's limiting because unless someone can travel back 65 million years, how can anyone be completely sure?"

Because Stan Winston wanted the Brachiosaurus in Jurassic Park to appear docile, the animatronic for the dinosaur was given a 4-axis jaw that allowed its jaw to move from side to side reminiscent of a cow chewing cud. It was the largest puppet that Stan Winston Studios built for the film that did not use any hydraulics. The animatronic head and neck was eight feet tall. Its sneeze was created from K-Y jelly, green and yellow food colorings, and a food thickener.

The cattle prods used in the beginning by the INGEN workers to try and subdue the Velociraptor were in actuality Mares Spear Guns with added bits and bobs on them.

The triceratops; so named because of its three horns; is the third dinosaur on the tour, and serves three purposes: it gets the guests outside of their cars so they can interact with a dinosaur, it delays them so they are out in the park when the hurricane hits, and it separates Ellie from the rest of the group.

The tyrannosaur's skin soaked up water during the filming of the main road attack. While they managed to dry it off between takes, it still retained so much moisture that it permanently expanded around the mid-section. The computer model had to be similarly "fattened up" in order to match.

ILM's Steve 'Spaz' Williams and Mark A.Z. Dippé were at first hired only to create motion blurs for stop-motion dinosaurs. In fact, their boss, Dennis Muren, expressly forbade them from wasting time on a computer-generated tyrannosaur, stating that Phil Tippett was already working on stop-motion dinosaurs, and trying to outdo his work would be "suicide". They did it anyway, and managed to "ambush" producer Kathleen Kennedy, by arranging for a walking, computerized tyrannosaur skeleton to be visible on Williams' monitor just when she walked by. She reported what she saw to Spielberg, who asked to see the animal with skin on it, which was also created by Williams. As "punishment", Williams was not invited to the screening where his results were shown to Spielberg, who was ecstatic, Stan Winston immediately got out and started making phone calls, and George Lucas reportedly cried at the beauty of a realistically animated dinosaur.

Jeff Goldblum had a very interesting and unique method for practicing and studying his lines between scenes on set, he wasn't studying it like most people who'd study quietly and kind of unobtrusively, he would speed read his lines out loud.

The phrase "spared no expense" is said five times.

In a Happy Sad Confused podcast, Samuel L. Jackson was asked about the possibility of Mace Windu, another character seemingly killed off in a previous film, returning to the Star Wars universe. Jackson said that he not only thinks Mace could return, he believes his character Ray managed to survive that raptor attack as well and has successfully adapted to a new life as master of the dinosaurs, still out there somewhere on that island. He stated: "It's the same way I think about the dude from Jurassic Park. He's somewhere riding around on velociraptors with one arm. He's just on that island riding raptors."

The idea that Tyrannosaurus' vision is based on movement is a reinterpretation of a plot element from the original Jurassic Park novel. In the book, numerous dinosaurs react only to movement, not just the T. rex. Dr. Grant is surprised that certain dinosaurs have impaired vision, and uses this to prove that the Park's dinosaurs are actually genetic freaks that were sloppily cloned and developed unwanted handicaps. In the movie however, the T. rex is the only dinosaur with movement-based vision and Grant considers it a natural attribute of the animal. In reality, no one ever truly suggested that T. rex or any other dinosaur would have had movement-based sight, in fact T. rex is believed to have had particularly strong eyesight, being able to pinpoint objects from miles away. The film also placed the T. rex's eyes much farther apart than in real life. Real Tyrannosaurus eyes were closer to each other, which would have improved its depth perception.

Sam Neill remembered attending the premiere with his son Tim who farted right next to Princess Diana.

Triceratops did indeed live in the jungle. The name means "three-horned face". The movie implies it had no protection from twentieth century plants, which could poison it.

The only movie in the franchise with a Dilophosaurus.

Editor Michael Kahn had a rough cut of the movie prepared just a few days after filming wrapped.

(at around 1h 35 mins) In one scene, Ian Malcolm mentions the Pirates of the Caribbean ride at Disneyland. This movie came out a decade before Pirates of the Caribbean: The Curse of the Black Pearl (2003) which is based on the Disneyland ride.

Phil Tippett's animatic version of the kitchen scene, was essentially the same, except the Raptors had snake tongues, the freezer door was shut, Tim fell by the door, and there were two exits; Lex and Tim went through the second one, et cetera.

Steven Spielberg's first toy was a Triceratops, which led to a fascination with dinosaurs, since they don't exist anymore, this interest culminated in the Jurassic Park film franchise.

Steven Spielberg and Kathleen Kennedy began recruiting the design team in the Summer of 1990. They wanted the freedom to create a reality, where their imaginations were unrestricted in Hawaii, on soundstages, or through CGI.

The Triceratops scene was a logistical nightmare for Stan Winston when Steven Spielberg moved up the shoot of the animatronics. It took eight puppeteers to operate it in Kauai. Gary Rydstrom combined the sound of it breathing into a cardboard tube with the cows near his workplace at Skywalker ranch to create the vocals.

Location shooting began on Kauai in August, 1992, for three weeks. Kauai was chosen, because it was the perfect environment, if you wanted to see a dinosaur, and it was strong visually. Steven Spielberg wanted the park to look as real as possible.

Any CGI shots of the T. Rex were done with wire frames at Industrial Light & Magic.

The Jeep being chased by the T. Rex (at around 1h 20 mins) was inspired by Hatari! (1962).

Claire Danes was among those considered for the role of Lex.

(at around 10 mins) John Hammond opens up a bottle of Moët & Chandon champagne which Grant and Sattler were saving, Moët & Chandon is one of the world's largest champagne producers and a prominent champagne house. The company holds a Royal Warrant to supply champagne to Queen Elizabeth II. Moët & Chandon was established in 1743 by Claude Moët, and today owns more than one thousand hectares (two thousand five hundred acres) of vineyards, and annually produces approximately twenty-six million bottles of champagne.

After the dinosaur molds were done, they were put over robotic skeletal structures. The next stage was movement. Phil Tippett wanted Steven Spielberg's storyboards done three-dimensionally with clay, to flesh out the scenes, and give them dimension, called Animatics, to act as a template.

Bob Peck was allowed to keep the prop Franchi SPAS-12 after filming was finished.

Production locations for the Visitor Center consisted of; Exterior: Valley House Plantation Estate, Kealia, Kauai, Hawaii. Interior: Universal Studios Hollywood, California. Visitor center lobby and rotunda: stage 12. Visitor center kitchen: stage 24. Visitor center control room, theatre, and dinosaur hatchery: Stage 28. V.I.P. dining room and visitors' dining room: unknown stage at Universal Studios, Hollywood, California.

Despite having the normal parts for a seat belt in the Jeeps it is noticable that ther seatbelts themselves were removed from the vehicles. This is just one more detail showing how Ingen believed they had more control than they really did and thus cut corners in terms of certain simple safety and security measures in the park. This makes Hammond's continued assertion they "spared no expense" ironic or possibly that the statement is only true of the flashier details such as celebrity speakers and gourmet food.

Joseph Mazzello's favorite part about his character was that "he was a little bit of a wise guy" around onscreen sister Lex (Ariana Richards). "I have an older sister," he said. "And so it was sort of fun to tease and poke and prod Ariana the way I would like my own sister."

Joseph Mazzello added, "To this day I feel like the animatronics with the computer generated CGI elements, that the way they were married in that movie, it stands the test of time. And I don't know that I've seen a film even since then that has really understood how you need both of those elements together to trick your eye into believing that everything is really there."

One thing the production crew wasn't satisfied with, was the Dilophosaurus. Specifically, that they couldn't find a convincing way to make it move on-screen. Every attempt either seemed too light or heavy for its body, so in the end they compromised and had it stand still in every shot.

The novel makes it very clear that the Jurassic Park theme park is a project funded by John Hammond's company, International Genetics Technologies, aka "InGen". However, in an effort to streamline the story, the majority of the branding in this film simply refers to Jurassic Park as a corporate entity; the name InGen is never spoken, and seen very few times on-screen: on the helicopter, employee ID badges, and a few computer displays. The sequel films more prominently feature InGen as the "greedy corporate interest" behind the parks.

(at around 1h 28 mins) Hammond repeatedly tells everybody very proudly "We've spared no expense." After the park goes completely to hell and his beloved grandchildren and Dr. Grant go missing, he talks with Dr. Sattler. He tries to explain the park to her, and she points out that the park was always doomed. Hammond is clearly completely broken, and she tries to make him feel better by complimenting the ice-cream, and he once again says, without any of his previous pride, "We spared no expense..." On closer examination, this line is somewhat ironic as there are indications it only really applies to things like celebrity speakers and gourmet food, whereas shortcuts have been taken with equipment and safety measures. This adds to the themes of illusion and the arrogance of believing they have more control than they do. It also fits with Hammond's character as both a showman and someone who has big ideas but is oblivious to the realities involved.

The audience doesn't see a dinosaur fully until fifteen minutes into the movie, when Grant, Ellie, Malcolm, Hammond, and Gennaro see the Brachiosaur.

Isla Nublar is stated to be one hundred twenty miles west of Costa Rica. However, there are no islands, of any size, west of Costa Rica for more than five thousand miles (eight thousand kilometers). Good thing this is a fictional story, otherwise the filmmakers would have a lot of explaining to do.

Dylan McDermott and Tom Sizemore also screentested for the role of Dr. Alan Grant.

The blip sound on the Silicon Graphics computers, and the blip on the Apple Macintosh Quadra 700, is a blip sound from a Motorola cell phone.

Animations for the computers in the labs and control room were lent from Silicon Graphics and Apple.

Steven Spielberg wanted the dinosaurs to be life-size at first, but deemed the idea too expensive and unconvincing.

James Woods was considered for the role of Gennaro.

The popularity of the film most likely influenced the nationwide vote in favor of the name "Raptors" for Toronto's NBA expansion team in 1994. A public viewing area for fans to watch the Raptors' matches, located just outside of the home team's arena, is widely referred from locals as "Jurassic Park".

Another change to Lex's character was that she was more sporty in the novel.

Dennis Muren scouted scenery for the full-motion dinosaurs at a ranch. But the water was shot at Lake Ewok at Skywalker Ranch.

Ian Bannen and Jon Pertwee were possibles for Hammond.

Michael Crichton adapted the script from his own bestseller.

Bollywood's top actress, Sridevi, was offered a role in this movie, but she declined.

(at around 1h 35 mins) John Hammond incorrectly states that the opening of Disneyland was in 1956. Disneyland actually opened to the public two days after Walt and Lillian's 30th anniversary, on July 17, 1955.

Shooting the film in the aspect ratio of 1.85:1 gave the audience 24% more vertical landscape within each frame. That meant he could shoot tall dinosaurs and make them look that way. Steven Spielberg utilized this inside the wide shots to really make the humans feel undersized and the world feel huge. In fact, Spielberg has been sneakily using aspect ratio to tell his stories since he started. But it wasn't only used for the dinos. Spielberg knew that this screenplay was truly about humans playing god. So once we got into the story, he had to devote the angle to show us looming over the dinosaurs. The entire first act of Jurassic Park sets up the hubris of humanity. We think we should be at the angle of looking down on our creations, but that's about to happen is that that awe and wonderment we used in act one to think we had a sense of control, it's about to be inverted into fear and anxiety as our creation physically looms over us and embodies our space. In the second half of the film, it's the dinosaurs time to loom over the humans. It starts small, with a T-Rex throwing its food onto a truck. Reminding us about being an apex predator. But then it's about use trying to share an earth with these creatures. And Spielberg has some tricks when it comes to scale here. The first is showing the dinosaurs in relation to objects we know. Like a car window. He also focuses on bringing dinosaurs into our world. Seeing them fumble around in spaces built for us, spaces they are truly too large to inhabit. One of the ways Spielberg exhibits these kinds of feelings is using a frame within a frame. That means showing a human POV via something from our normal walk of life while showing a dinosaur intersecting with it. Like this raptor in the window. Spielberg and Dean Cundey had fun putting these shots all over the screen. Constantly reminding us the power shifts and scale of these creatures. I know all this seems like things people playing with big budgets can do as much as they want. But think about how little tweaks to your work can push the story forward.

Dennis Muren doubted a real T. Rex would look like the one in the movie. It wouldn't be as aggressive, because when bears fight on their hind legs, they can only do it for six to seven seconds before collapsing. Dinosaurs that did the same would wear them out. However, that is only speculation.

Work began at Stan Winston's studio, in 1991, with the look of each character; Winston felt it was important in convincing the audience, otherwise the movie would fail, no matter how good the performances were.

Early in the development of the first film, Phil Tippett lobbied for the Apatosaurus from the novel to be replaced by Brachiosaurus or Ultrasaurus in the film adaptation because the aforementioned sauropods were bigger than Apatosaurus and Tippett felt that the sauropods he was lobbying for had a "much more interesting design" physiologically. Ultimately, Brachiosaurus was the sauropod that was picked for the film, though Ultrasaurus would later appear in Jurassic Park: The Ride.

The Brachiosaurus rehearsals were taken in the shop at Stan's [Stan Winston Studio] before the Brach was packed up and taken to stage 28 at Universal [Studios]. Its a seven and a half foot tall puppet that included the head of course and part of the neck. The jaw is a 4-axis jaw so it has up and down movement and side to side. The reasoning behind that was Stan wanted the Brach to appear to be as docile as possible, so one of the things that a 4-axis jaw gives you is that sort of orbital movement of the lower jaw grinding side to side which is reminiscent of a cow chewing its cud. And we thought, "Well, that certainly can't be bad." So we grabbed some vines from out in front of the building and we put them in the Brach's mouth. At this point the tongue is moving also, and the lips are moving, a little too much, but that's something you learn as you go. So it's a matter of a number of people coordinating. And I think there were six of us altogether puppeteering on the Brach. There was someone on the eyes, someone on the tongue, I was on the jaw movement. There's someone on the lips. And the big move was the neck movement. There was head movement but there was also neck movement where the whole thing could pitch forward and back. It was the largest puppet we built that had absolutely no hydraulics in it. So it was weighty and a big challenge to get to move. I got quite a workout on the jaw, making a big circular motion with this giant controller, getting everything moving and grinding properly."

Dilophosaurus was actually 20 ft long and was the largest predatory dinosaur in its environment at the time.

When Steven Spielberg started working on Jurassic Park, his plan for photography of full-scale dinosaurs in long shots was to use go motion animation, building on the traditional techniques of stop-motion. That all changed, however, when Spielberg was asked by artists at Industrial Light And Magic about the possibility of using CGI for the work. Not initially convinced it would work, the director had them do a test and was blown away by what they made, which featured a Tyrannosaurus Rex walking across a still nature image, and then chasing a herd of Gallimimus.

As much as things changed on set, what allowed this to happen was meticulous planning done by Steven Spielberg, who went as far as to create scaled models versions of scenes and used a lipstick camera to find all of the angles he wanted to shoot.

Steven Spielberg and Michael Crichton were originally working together on ER, before Crichton mentioned having written a novel about dinosaurs. ER later became a hit television series. Some members of the cast have connections to the Jurassic Park series: William H. Macy appeared in Jurassic Park III, James Cromwell appeared in Jurassic World: Fallen Kingdom, and Diane Ladd, who made a guest appearance on ER, is the mother of Laura Dern.

Michael Crichton receives a screenplay credit, and many reviews and promotional materials credit him for "adapting his own novel." This is only partially true. Crichton wrote the first draft of the script and did one revision before leaving the project. He left not because he disapproved of the direction the project was taking (as he had done with Rising Sun (1993)), but because he had not wanted to write the script in the first place, due to how difficult writing the novel had been. However, he felt he knew what could be cut to bring it down to a reasonable budget, and what changes to avoid to make sure the story still worked. He told Spielberg in advance that he would want someone else to polish the characters and make other refinements. The final draft, though it includes many elements straight from the novel, is more David Koepp's product than Crichton's. Under WGA rules, the writer of the first draft always gets a credit, unless the final draft is drastically different or that writer declines credit.

When Jurassic Park premiered on Australia's Seven Network in 1996, it was the highest rated movie broadcast for that year (2,362,000).

Danny Glover was considered for the role of Ray.

When creating the concept art for the Parasaurolophus featured in the first film, Mark 'Crash' McCreery used a duck's bill as a reference when creating the hadrosaur's mouth and the eyes of a deer to make the dinosaur seem quiet and docile. Two proposed colorations were made by "Crash" McCreery. One was a beige color with a dark gray crest and back with dark brown stripes on the thigh and the other's coloration had the whole head and neck as red, the torso being a darker tan with some of this tan being on its back instead of black like the first coloration and the stripes on its thigh being black as opposed to dark brown. The final film's Parasaurs have greenish colored skin with a black back and seemingly lacks striping while its other details are unidentifiable due to the duckbill dinosaurs being difficult to see clearly. TyRuben Ellingson painted the digital maps used for the color of the Parasaurolophus as well as the Brachiosaurus in Jurassic Park. At one point, sexual dimorphism was considered, with the species P. walkeri being the males and the females being the species P. cyrtocristatus. The mural of the dinning room featuring Parasaurolophus painted by Doug Henderson still utilizes this scrapped idea.

The T-rex vocalizations that were created by Gary Rydstrom are also a popularly used sound effect. Jurassic World (2015) sound designer Al Nelson said regarding how famous its roars were in the films: "The T. rex is one of the most iconic sounds in all of film history. Every sound designer knows it. Almost any kid knows it. When you hear it you're like 'That's the T. rex!'"

Brachiosaurus was the first CGI dinosaur to be created during post-production of Jurassic Park. During the creation of the CGI model, director Steven Spielberg would frequently critique it. Spielberg requested that the Brachiosaurus that appeared in its reveal scene be made larger, but when Industrial Light and Magic made it twice the size that it was intended to be, the dinosaur towered over the branches when it reared up on its hind legs. To counteract this, the head and neck of the Brachiosaur's model were lowered so it could reach the branches that were below it. TyRuben Ellingson painted the digital maps used for the color of the Brachiosaurus in the film. The movements of the Brach were based on both the elephant and the giraffe. The giraffe was used for the sauropods long strides and grace while the elephant gave it the weight and mass as it moved.

The Ronto for the Star Wars: Episode IV - A New Hope (1977) 1997 Special Edition was created from a modified model of the Brachiosaurus from this film. Industrial Light and Magic even referred to the Ronto as "Bronto" before it was named "Ronto", which was the name George Lucas gave to this alien creature that is simply its production nickname with the "b" dropped. The Brachiosaurus model from the first film was also retrofitted to serve as the Mamenchisaurus for the sequel to this film, The Lost World: Jurassic Park (1997).

The film crew contacted paleontologist John Ostrom and requested all copies of his technical papers of Deinonychus and this dinosaur served as the primary basis for the Velociraptor seen on screen. The film's Velociraptor was to even be called Deinonychus at one point in the film's development in 1991.

The final design of the raptor was sculpted by Christopher Swift. The color scheme of the raptors changed throughout its development. Mark Hallett did color studies of the raptors featuring them with vibrant colors. Each of these colorations was as follows: bright red with black striping, yellow and brown with orange highlights, and olive green and blue. All of these, however, were discarded. One early proposed coloration was orange with black stripes, like a tiger. This coloration is showcased in Craig Mullins' concept art of the final scene. The practical raptors created by Stan Winston Studio were painted with yellow and orange in their color scheme, but due to the cool lighting when filming with the practical effects of Velociraptor the bright yellow exhibited in their color scheme ended up subdued.

For filming the lower half of the raptors, leg extensions consisting of the lower torso, legs, and forelimbs was created. The forelimbs and toes were cable operated with John Rosengrant strapped into the extensions to portray the moving dinosaur. Other effects were used such as a floppy rubber raptor strung up by cables with a pole-operated head that was attached to Bob Peck during his character's death scene, a full-sized puppet with an armature that was used as a stand-in for the CGI raptor, and a full-body puppet with locking joints and an articulated head that saw usage when a Velociraptor leaps onto the gate of the Maintenance Shed. Furthermore in the scene in the shed, insert arms and an insert leg puppeteered by Rosengrant were also used.

The insert head was used for close up shots of the raptors. It was used in every scene that featured the sickle-clawed predators. This insert head, along with two other puppets, was designed and built by Craig Caton, who had been interested in creating a puppet utilizing a Steadycam design after watching Steadicam operators during the filming of Batman Returns (1992). The head and the aforementioned puppets utilized a modified version of the neck mechanism of the Dilophosaurus animatronic. Originally the insert head was going to use a different method until it was changed to an offshoot of the Dilophosaurus neck design. Unlike the Dilo's head, the Velociraptor head borrowed more from Steadicam technology. Using a standard backpack rather than one used for Steadicams, the base of the head had a handle that when grabbing it in a certain direction would allow the head to move in that direction. Its tongue, eyes, and lips were radio controlled and its mouth was cable controlled. Christopher Swift and Mark 'Crash' McCreery operated these parts of the head respectively. Also utilizing Craton's Steadicam neck mechanism were two cable puppets, one spanning from head to tail and the other without a tail with a rod that came out of its back. The reason for the latter puppet's lack of tail was so that the crew could operate it in tighter areas.

For the hatchling, Gary Rydstrom aimed to find a baby animal that had raspy vocalizations as the adults would make similar sounds. Rydstrom and his team recorded various baby animals including those of owls and foxes for the newly born raptor. The baby owl sounds were used for the baby's vocals upon Dr. Grant discovering its identity.

The production budget was $63 million, while the advertising budget was $65 million.

Just as the tour begins, Hammond is watching a monitor showing the onboard camera views of the Explorers. Just before he switches over to the car Lex and Tim are in, the monitor shows Ian sitting with his arm on the back of the seat across Alan's shoulders, and Alan turning toward him in a "What the hell?" sort of fashion.

The dilophosaurus was sculpted by Adam Jones of Tool.

when Tim meets Dr. Alan Grant, he says "I read your book." The book Tim refers to is a copy of Digging Dinosaurs by Dr. John "Jack" Horner, who was the scientific consultant for Jurassic Park. Grant's book has a forward by Sir Richard Attenborough, who played John Hammond.

To Gary Rydstrom's credit, the throaty sound the T. rex makes right before and after it engulfs the goat does bear a resemblance to the kind of throaty vocalization from an alligator or a koala, both of which Rydstrom cites as part of the mix.

As Gary Rydstrom recalled to NPR in 2013: "We started recording all kinds of weird animal sounds, I tried to get every interesting animal recording we could find, not even caring right away what they would be for Then you try to sift through [the recordings] in the studio and see what's interesting." And in a 2015 interview with Vulture, he explained, "One of the fun things in sound design is to take a sound and slow it down It becomes much bigger."

To accomplish the theater-shaking T. rex roar, Gary Rydstrom was looking to create something that sounded otherworldly and massive but still believable and organic. And, most importantly: he was trying to establish an ancient, elemental enemy.

Ray Wise was originally up for the role of Gennaro, as Spielberg had been a fan of his performance in Twin Peaks (1990). He ultimately signed on for Rising Sun (1993) however, as director Philip Kaufman offered him the role before anything was set in stone with Spielberg.

Sam Neill admitted he hasn't seen the original movie that many times. "Well, I've probably only seen the film two or three, maybe four times, and that would have been in 1993. So it's not something... [laughs]. Matter of fact, I was walking through a shopping center the other day, a big shopping mall, and there was this music playing. And I thought 'That's kind of familiar music.' And the person I was with said 'Do you recognize this music?' I said, 'It seems familiar.' And they said, 'You're so silly, this is the theme for Jurassic Park, for goodness sake.' Oh, yeah, you're right. You're right." Neill shared.

Sam Neill was asked about how involved Spielberg was in dictating how the paleontologist should react to seeing his old, dusty fossils literally come to life right in front of him for the first time. According to the actor, other than the famous moment where he forcibly turns Laura Dern's head to look, he was largely left to his own devices: "I suggested something, which is an illustration of how I was never an action hero. I said to Steven, 'Look, after a lifetime of imagining dinosaurs, to actually see a dinosaur, Alan Grant just might flat out faint' And Steven said, 'Yeah, okay.' So that's why you see me stagger around and I have to sit down and put my head between my legs."

Jeff Goldblum shared that he couldn't recall why and how Ian Malcolm came to create that beloved and steamy image. In his words: "[Laura] said, 'Oh, no no. I think, whether you see it,' and I don't think maybe you see it much, but I think I was injured also around [my abdomen]. And there were bandages and there was blood and I think we were attending to that, etc I forgot about it entirely, it was just Laura that reminded me yesterday that's maybe what happened."

While Ellie's observation regarding the plants is included in the film, it is cut down to the point that the seriousness of it is lost. Ironically, this reflects her thoughts in the novel that people do not truly understand plants and thus fail to see that they play an active role in the environment equal to that of animals. They are more than a backdrop or ornamentation. The specific plant referred to is a type of fern whose spores carry a substance 50 times more poisonous than oleander, and just touching the plant could make a person sick. She further notes that if a child ingested it they would most certainly die.

The prop department created an entire set of severed limbs for Samuel L. Jackson's character. On Laura Dern's first take of the scene where she runs from the raptor, her radio and head set fell to the ground and managed to entangle all four prosthetic limbs, dragging them behind her as she ran.

The gate that the cars go through during the guided tour was specifically modeled after the gate from King Kong (1933) on link=nm0000229]'s request; hence Ian Malcolm's remark "What have they got in there, King Kong?"

The raptors' behavior was based on the now discredited idea that small predatory dinosaurs hunted in coordinated packs. This hypothesis originates from the late 1960s, when a number of carnivorous Deinonychus were discovered around the skeleton of a large plant eating dinosaur called Tenontosaurus. The discovery lead to the scientific revolution known as the "Dinosaur Renaissance", and for many decades dromeaosaurs (aka raptors) were depicted in books, movies, games and toys as pack hunting predators that latched onto their prey as a group and slashed it to death with their enlarged foot claws. Gradually, this hypothesis lost its scientific support. Unlike what the film tells us, raptor claws were not suited for cutting as they had no sharp edge. Chemical analysis of their fossil bones showed adult raptors ate different types of food than juveniles, whereas animals that live in packs usually share the same meal. The raptor fossils found next to the Tenontosaurus were likely scavengers, as carnivores tend to gather around large carcasses. It is now believed raptors hunted alone or in small but mostly uncoordinated groups, killing smaller animals using the "Raptor Prey Restraint" technique, clawing and gouging their victims to death while pushing them to the ground. In the original Jurassic Park novel, this is how Dr. Wu was killed.

(at around 1h 20 mins) The Jeep being chased by the T. Rex was allegedly going forty miles per hour, and the movie no doubt exaggerated the T. Rex's running speed. A real one could run up to twenty-five miles per hour. Another point rendered moot by the fact that this is a fictional story.

This movie abandons somewhat Michael Crichton's attitude that dinosaurs are wholly dangerous, but also takes the time to see the wonder in them as well.

The advents in CGI allowed the dinosaurs to appear three-dimensionally, and for the animators to work out their muscle structure and how they would move.

The Ford Explorers paint job was designed to look like a dinosaur skin pattern, which was a factor in Rexy attacking them. Her vision is poor she thought other dinosaurs invade her territory.

One shot involved the tour cars driving over a land bridge. The cars were in fact controlled by stunt drivers whose only view of the road was on a small television monitor. Joseph Mazzello's father considered this unsafe, and forbade him from appearing in that shot. It was completed with his stunt double, and ended up bot making the final cut of the film.

The scene that introduces the Tyrannosaurus Rex, from the shot of the bleating goat to the T-Rex's final roar, is entirely without music.

The baby Triceratops scene may have been cut, because it was too comical a scene for the latter half of the movie.

The Brachiosaurs are supposedly the largest dinosaurs in Jurassic Park.

The goat that eventually gets eaten by the Tyrannosaur is shown at times standing and also lying down. Later, a bloody goat leg drops on the windshield of a car, startling the occupants. The goat was filmed standing and responded to verbal cues to lay down. The leg that dropped on the windshield was a fake prop embelished with movie blood.

Jake Gyllenhaal was among those considered for the role of Tim.

Dilophosaurus, along with Procompsognathus and Troodon, are the only known venomous dinosaurs in the Jurassic Park franchise.

In popular culture, Tyrannosaurus has an iconic status shared by few other species, helped in no small part by the prominent role of the T. rex in all five films in the Jurassic Park franchise. The design of the Jurassic Park franchise's Tyrannosaurus is a notably popular way to depict Tyrannosaurus in media.

The self-driving Ford Explorers where actually driven by single crew members crouched in the back of the cars. Crew members use cameras attached to the front of the cars to see where they were going.

Michael Crichton wrote the novel when he and his wife were expecting their first child, and it is dedicated to the two of them ("For A-M and T" refers to Anne-Marie Martin and Taylor Crichton). Despite knowing his child would be a girl, and having made all the dinosaurs female, the novel still gives most of the action to the male characters. For example, Tim is both a dinosaur fan and computer expert who uses those skills to restart power in the visitors' center, while it is Mr. Arnold, then Donald Genarro, then Grant, who make an attempt to turn the circuit breakers back on. The film gives these actions to the female characters. Lex is the computer expert who reboots the security systems, while it is Ellie who successfully reactivates the circuit breakers. In another bit of role reversal, not from the book, but just movies in general is that it is Ian Malcolm seen with his shirt undone as a bit of eye candy, while Ellie is a strong female character who is attractive, but not overly sexualized.

Ellie at one point remarks "Dinosaurs eat man, woman inherits the Earth." One could argue this describes one of the changes made in the film. One man (Gennaro) is eaten by a dinosaur even though this doesn't happen in the novel, and his role in the plot after that point is taken up by Ellie. It is she he ventures out into the park with Muldoon to look for survivors of the T-Rex attack, and later to reboot the power. She actually starts taking his role before the T-Rex attack: Malcolm directly explains chaos theory to her using the drop-of-water-on-the-hand analogy, something that Arnold uses to explain it to Gennaro in the novel. Ellie also stays behind alone with the Triceratops, while in the novel, Gennaro stays with her.

There is only one real dinosaur in this film despite hundreds of dinosaurs being seen on screen. It was loaned to the production by the San Diego Zoo but it is not authentic to the time as they only have a "Triassic Park." Cretaceous World was not happy with this partnership and it lead to the great Mesozoic War of 251.9 Million BC.

Brian Cox was interviewed for the part of Muldoon.

(at around 1h 4 mins) The second choice for the role of Ian Malcolm was Jim Carrey. He and Jeff Goldblum appeared in Earth Girls Are Easy (1988). Carrey also appeared in Ace Ventura: Pet Detective (1994), in which he remarks "Man, I'm tired of being right!" In this movie, Malcolm says "Boy, do I hate being right all the time!"

Laura Dern's previous movie, Rambling Rose (1991), also featured John Heard, who performed the audio book version of Jurassic Park.

Geoffrey Rush was considered for the role of Muldoon.

Many plot points and Easter Eggs call back to earlier films in Spielberg's career. Like Jaws, the plot revolves around vacation spot threatened by out-of-control animals. Both films also begin with a character being killed by the animal. As with Close Encounters, he cast a filmmaker as a character who brings humans in contact with fantastic creatures. Like Raiders, there is a scene set at a desert excavation. Nedry dressed like the kids from The Goonies, and watches Jaws on his computer. Arnold's "Hold on to your butts" line came from Robert Zemeckis. Grant, reluctant to become a father, becomes more comfortable with the idea because he looks after two kids whose parents are getting divorced. Spielberg himself experienced that while filming E.T. In retrospect, the homage to The Shining found in the kitchen scene foreshadows his involvement in A.I.

(at around 1h 35 mins) The scene when the T. Rex charges out of the trees to get the Gallimimus was inspired by a scene similar in The Valley of Gwangi (1969). Which was another movie by which Steven Spielberg was inspired.

Charlie Sheen was considered for the role of Nedry.

Crew member Michael Backes was recommended by both Industrial Light and Magic and author Michael Crichton, who had actually called on him fact check the novel's technical details. ILM had used him to help their computer animation render on film with proper resolution. He had his own connection to the cast as well: his (now ex-)wife, director Martha Coolidge, had directed Laura Dern in Rambling Rose (1991).

When designing the Brachiosaurus for the first film, Mark 'Crash' McCreery visited a zoo that was keeping African elephants. He studied the elephants to give the film's Brachiosaurus its impressive mass and weight. From studying these animals, it also helped give the skin of the Brachiosaurus a tough and leathery look.

In 1990, Paleoartist Mark Hallett created a storyboard of the raptors in the kitchen and color studies of the raptors. John Gurche, another well-known paleoartist, also created concept art of the raptors. His concepts depicted the raptors with long, chicken-esque feet. These drawings featured a different head design than that of the film. Gregory Paul skeletal and muscle studies of the Velociraptor for the film, though Paul has said that he never received any feedback on the diagrams he created of the raptors.

(at around 24 mins) The scene with Hammond interacting with the Mr. DNA animation is a nod to Winsor McCay's Gertie the Dinosaur (1914) the first animated short film to feature a dinosaur. It was a vaudeville act where the artist would interact with the animated character, much like Hammond does on the tour.

Laura Dern and Jeff Goldblum appear in this film opposite Richard Attenborough, an actor-turned-director who returned to acting for this film. Both actors have worked with several other actor-directors as well. Steven Spielberg appeared in The Blues Brothers for director John Landis, who frequently gets fellow film makers to make cameos in his films. His subsequent film Into the Night starred Goldblum, along with several other directors, most notably Lawrence Kasdan and David Cronenberg, who directed him in The Big Chill and The Fly. Dern frequently works with director David Lynch, the last such collaboration being Twin Peaks, in which he also acted. Later this year, Dern worked with two other Oscar-winning actor/directors, Kevin Costner and Clint Eastwood, in A Perfect World.

Stan Winston, Dennis Muren, Gary Summers, and Gary Rydstrom all previously worked together on Terminator 2: Judgment Day, for which they all won Oscars. Winston and Muren received theirs from Laura Dern, just five months before production began on this film. The next film to win that Oscar had connections to this one as well: Rick Carter and Dean Cundey both worked on Death Becomes Her, which was also co-written by David Koepp. Cast members Meryl Streep and Isabella Rosselini have also both worked with Sam Neil and Laura Dern, in Big Little Lies, Little Women, Blue Velvet, Wild at Heart, Plenty, A Cry in the Dark, and Merlin.

While the theatrical poster and all home video editions have listed all 11 cast members in the credits, much of the other promotional material; such as the soundtrack and tie-in edition of the novel, credited only the above-the-title cast: Sam Neill, Laura Dern, Jeff Goldblum, and Richard Attenborough. After the title were only the crew credits.

when the movie was being filmed, only seven T. rex skeletons had been discovered.

In the novel, another maintenance building, Maintenance Building 04, has a number. Because of this, this building also most likely has a number (possibly 01 due to its close proximity to the Visitor Center), but it was never mentioned in the novel.

Sir Richard Attenborough's previous movie, Chaplin (1992), featured David Duchovny in a small role. Duchovny's ex-wife, Téa Leoni, appeared in Jurassic Park III (2001) and A League of Their Own (1992), the latter of which also featured Jeff Goldblum's ex-wife, Geena Davis. Duchovny appeared on Twin Peaks (2017), opposite Laura Dern. He also hosted an episode of Saturday Night Live (1975), in which he played Goldblum.

Two of Steven Spielberg's most popular cartoons ended and begin in between this films production and release. Tiny Toon Adventures (1990) final episode aired December 2nd, 1992 six months before the films release date. While Animaniacs (1993) first episode aired September 13th, 1993 four months after the films release.

During the early parts of the film, various pieces of tech or equipment in the park make hissing noises. These sounds are similar to the vocalizations made by the velociraptor.

In the Visitor's Center, there is a banner with the words "When Dinosaurs Ruled The Earth." In 1970 a film about cavemen and dinosaurs was released with those exact words as the title.

There is usually an evil businessman or administrator who is colluding with the bad guys in Spielberg's films; or aiding them in some way. In Jaws, Murray Hamilton played Larry Vaughn, the evil mayor who insisted the Amity beaches stay open even after he was aware Christie Watkins had just been eaten by a serial killing great white shark days beforehand. In Poltergeist, Mr. Teague, Steven Frieling's boss, fails to tell the Frieling family that their house was built on a cemetery. In Raiders of the Lost Ark the evil government administrator Major Eaton confiscates the Ark at the ending; even after Indiana Jones has nearly killed himself to get it; and has it holed up in storage; never to be seen again. The evil government administrators in Close Encounters falsely tell everyone there is has been a toxic nerve gas leak throughout the state of Wyoming; just to get everyone to flee so they won't see the aliens when they land. They even kill Jillian Guiler's bird as part of the cover-up. The evil government administrators in ET try to confiscate the alien so they can study him; as opposed to letting him get to his space ship and go home. They even use guns in their attempts to stop the children and their escape plan. And in Jurassic Park there is the evil lawyer Donald Gennaro; who crossly warns John Hammond he will shut down the park at the film's beginning; and then crossly warns Lex and Tim Murphy not to break any of the expensive equipment later; and pushes for the park to stay open even after Elle Statler, Alan Grant and Ian Malcom all warn him that it is not safe. Then he abandons Lex and Tim Murphy when the T-rex attacks them near the weigh station; and selfishly flees into a restroom to save himself there; leaving the kids to helplessly fend for themselves. There is also the evil Jurassic Park administrator Dennis Nedry who sets the tragic events in play in the first place. He's the computer network engineer at Jurassic Park who betrays John Hammond (and everyone else) by attempting to sell the Park's secrets to a rival of Hammond's; and unwittingly unleashes the dinosaurs which kill off most of the crew and visitors as a result.

In the novel, Ian Malcolm says he only wears black because he believes his life is "too valuable to waste thinking about clothing." In this film, The Lost World: Jurassic Park, and Jurassic World: Fallen Kingdom, he primarily wears black.

The velociraptor eyes were based on a snake and underwent about 15 different designs. The final product included a sculptured core and cell work.

The gas Jeep the T-Rex chased has a red stripe across the door on both sides. In the novel, the Triceratops would try to ram Jeeps out in the field; after experimentation, they discovered a red stripe would make the Triceratops leave the Jeeps alone.

The pilot who airlifts the crew to safety after the hurricane is the same pilot who rescues Indiana Jones in the opening scenes of Raiders of the Lost Ark,

Richard Attenborough's role had originally been offered to Sean Connery,

Sam Neill, whose real name is Nigel, plays Alan Grant. Steven Spielberg's middle name is Allan, while his son Max Spielberg's middle name is Samuel. Richard Attenborough's name was also Samuel, and he and Spielberg have both directed Nigel Hawthorne in a film: Gandhi (1982) and Amistad (1997).

It's possible that the Dodgson character was named after Peter Dodson, a well-known American paleontologist.

The film differs significantly in not only characters but also plot. In the book, several InGen employees were killed by out of control dinosaurs, some of whom escaped to the mainland. This prompted experts to review the island and the company's abilities. John Hammond is a cold and rather heartless businessman who, after everything that happens in the park, thinks the situation can be salvaged. He also did not survive the book when a pack of Compies eat him after he fell down a hill and broke his ankle. The cause of which was him being startled by the roar of a T-Rex which was truly his grandchildren messing with the park's PA system. Ian Malcolm is largely like his movie counterpart. The major exception being, he died at end of the book from his injuries from a T-Rex. This fact was given a retcon by the author enabling Ian to appear in the sequel "The Lost World". Dr. Grant was a widower and both he and Ellie Sattler do not have a romantic relationship because Sattler is married to another character. The lawyer Gennaro survived in the book only to die of dysentery during a business trip in 'The Lost World' novel. The game warden, Robert Muldoon also survived the novel but hunting the Velociraptors with a rocket launcher. John Arnold, in both film and book, is killed by a Velociraptor. The reason it wasn't shown in the film was due to a real tropical storm destroying the set before it could be filmed. Genetics engineer Henry Wu was eviscerated and eaten by the Velociraptors towards the end of the novel. Hammond also blamed Wu for the park's failure because the engineer was too keen on enhancing the dinosaurs, a trait carried over into the film's canon, rather than replicating genetically accurate dinosaurs for the park. The novel also has many secondary characters, employees of the park, being killed by the escaping dinosaurs. A fact not shown in the film as the employees are evacuated to the mainland ahead of the storm.

In 2022, while promoting Jurassic World: Dominion, Laura Dern made 29 years after the original Jurassic Park's release disrespectful and ageist statements regarding couples and relationships with age-disparities by calling the age-disparity between her character Ellie Sattler and Alan Grant "inappropriate", this aggravated also by the fact that many people in Hollywood and entertainment industry (and also out of it) are engaged in relationships and marriages with considerable age-disparities and around that same time comedian Dane Cook (50) and Kelsi Taylor (23) announced their marriage after being engaged for 5 years, announcement followed by ageist insults, bullying and attacks on social media.

When considering how to give voice to Jurassic Park's dinosaur, tortoise mating sounds might not be the first thing that springs to mind, but to sound designer, Gary Rydstrom, it was an ideal choice. Speaking to Vulture, Rydstrom explained that one benefit was that "tortoises mating can take a long time. You've got to have plenty of time to sit around and watch and record them." In other words, the tantric tortoises gave Rydstrom more than enough material to work with. Moreover, their coital calls sounded totally alien, making them perfect for a creature no one has ever heard before, and ensuring audiences would not be able to readily identify the sound. However, while the sound itself proved ideal for the velociraptors, recording it put Rydstrom in a less-than-ideal situation. Rydstrom set up recording equipment at Marine World and sat around for hours while the resident tortoises mated. "It's kind of embarrassing," Rydstrom said (via Vulture). "The people there said, 'Would you like to record these two tortoises that are mating?' It sounded like a joke." In the end, though, the results proved worth the wait.

Wayne Knight (Dennis Nedry) was the first actor to be cast.

Harrison Ford turned down the role of Dr. Alan Grant and worked on The Fugitive (1993) instead.

Michael J Fox and Johnny Depp screen tested for Dr Ian Malcolm.

Laura Dern, who works in this film with actor-turned-director-turned actor Richard Attenborough, has also worked extensively with director David Lynch, who also acted opposite her on Twin Peaks. Dern was instrumental in getting Lynch to appear in Spielberg's subsequent film, The Fabelmans.

Richard Attenborough's daughter and granddaughter were killed in the 2004 Thailand tsunami, making it pretty uncomfortable seeing him in a story about the unstoppable power of nature, which puts his character's grandchildren in danger.

Dodgson advising Nedry not to use his name and acting covert became this when his actor was sentenced for child molestation.

Whit Hertford, who plays the volunteer kid who annoys Alan by calling the Velociraptor fossil a "six-foot turkey", later voiced an animated dinosaur himself in The Land Before Time III: The Time of the Great Giving (1995). he has a musical number in that film called "When You're Big"

In the early scenes before the tour, Hammond's guests eat Chilean sea bass, a fish that was considered new and trendy in fine dining in the early 90s. Later in the decade, the increasing popularity of Chilean sea bass would lead to overfishing and the need for regulations to prevent the fish from becoming endangered. Another small unintended wrinkle to have in a film about extinction.

When the raptor jumps after the characters who've fled through the hatch in the ceiling and it falls to the floor, we see it land with its head flung back almost double and its limbs folded up. This is a very typical pose for such small, lightly-built theropod fossils to be found in.

One behind the scenes story tells of how a crew member had to crawl inside of the animatronic T. rex to glue its skin on. The power cut out and the animatronic's hydraulics nearly sliced the worker to ribbons. Fast forward 21 years, and a horror game franchise would use that exact date for multiple characters, including the main antagonist.

When the tour begins and the jeep rolls through the Jurassic Park gates, Malcolm quips "What do they got in there? King Kong?" (which is a tip of the hat to the design of the gates, taken from the original King Kong (1933)). In 2016, Universal Studios would open up Skull Island: Reign of Kong on Islands of Adventure, next door to the island devoted to the Jurassic Park River Adventure ride.

When Hammond compares the problems facing his park to those of Disneyland when it first opened, Malcolm retorts, "Yeah, but John, if the Pirates of the Caribbean breaks down, the pirates don't eat the tourists." While the pirates had nothing to do with it, in 2016 a large reptile (an alligator) killed a child visiting Disney World, much like in Jurassic Park. In response, Disney removed crocodiles and alligators as well as all references to them from their parks.

The Ford Explorer was the tour vehicle in Jurassic Park, this is the model from 1992, it was electrically guided over the rail in the road. They were equipped with a panoramic glass roof, leather seats, video information system, night vision goggles under the seats, information brochures and a device box in the trunk. The film featured numbers 4 and 5.

The Jeep JP 10, which is not equipped with a roll bar - but with two toolboxes - is driven by the Robert Muldoon.

The JP 18 and 29 open-top jeeps appear at the beginning of the film as John Hammond drives the test visitors to the Jurassic Park Visitor Center.

1st Park Cars are the 2 Jeeps 18 and 29.

The Jeep JP 12, equipped with a fully enclosed top, automatic transmission and a winch (front), is driven by Dennis Nedry during his theft of dinosaur embryos from Jurassic Park.

In this order, the main characters appear: Muldoon, Grant, Ellie, Hammond, Nedry, Malcolm, Wu, Lex and Tim.

Order of the Cars appearance (Explorer / Jeeps). 18, 29, 04, 05, 12, 10.

Ellie's tanktop and shorts in the film was the influenced of Lara Croft's look in the Tomb Raider video game series.

Jeff Goldblum and Samuel L. Jackson appeared in Fathers & Sons (1992).

Sam Neill's mentor, James Mason, appeared in North by Northwest (1959). His character's entrance was recreated by Spielberg in Indiana Jones and the Last Crusade (1989). He subsequently worked with director Stanley Kubrick on Lolita (1962). He was also later allowed to visit the set of Kubrick's film The Shining (1980), which Steven Spielberg also visited, leading to his friendship with Kubrick and eventually directing A.I. Artificial Intelligence (2001). Neill made two references to Kubrick's films during the course of this year. The scene in which Tim and Lex are hunted by velociraptors in the kitchen features an homage to The Shining, which Neill's guest spot on The Simpsons: Homer the Vigilante (1994) featured Homer riding a bomb to destruction a la Slim Pickens in Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964).

For the 1994 holiday season, McDonald's, whose responsible for being the official fast-food partner for the film's theatrical release a year prior, and MCA/Universal Home Video team up for the holiday film festival with the $3 rebate offer, with the completed form and the required proof of purchase from the Jurassic Park video, when customers purchase one of the four titles: An American Tail: Fievel Goes West (1991), Back to the Future (1985), Field of Dreams (1989) and The Land Before Time (1988)

Joseph Mazzello was "scared to death" when he first read the script, he told in an interview with TODAY, "It just seemed incredibly intense and really fun. And my imagination just ran completely wild. I was really looking forward to see these dinosaurs. I remember that for the first couple weeks or about a month that we didn't do any scenes with the dinosaurs. And I was just dying to see them. And the first one I saw was the triceratops laying there when he's sick and just couldn't believe my eyes at how incredibly lifelike it was."

The scenes in the maintenance shed were filmed on Stage 23. The Dilophosaurus scene was filmed on Stage 27.

Grant and Sattler first appear in Montana. The novel was first published in 1990, when both Sam Neill and Laura Dern made films connected to Montana. Neill appeared in The Hunt for Red October (1990), in which his character wants to migrate to Montana. Dern appeared in Wild at Heart (1990) for Montana-born director David Lynch. Also appearing in that film was her mother, Diane Ladd, whose own dinosaur picture, Carnosaur (1993), featured the Deinonychus, who remains have been unearthed in Montana.

Laura Dern's character first appears at a dig site in Montana. Aside from this role, Dern is best known for her work with writer and director David Lynch, who was born and raised in Montana.

One of two movies in 1993 in which Laura Dern co-starred with a veteran actor and director. The other movie was A Perfect World (1993), in which Dern co-starred with Clint Eastwood.

One of two 1993 releases in which Laura Dern has had a young co-star, Joseph Mazzello in this movie. The other young co-star of Dern's was T.J. Lowther in A Perfect World (1993).

Steven Spielberg's last film not to feature Janusz Kaminski as cinematographer. He began using him on Schindler's List (1993), and Kaminski has photographed all of Spielberg's films since.

During the Velociraptor feeding scene, Hammond never takes his eyes off of Grant. He's watching for something and his face twitches into the faintest of smile. For Grant isn't watching in horror as Hammond probably feared but in enraptured fascination. Also considering that later in which Hammond explains how his first attraction was a flea circus. With little motors controlling everything he's an illusionist. He's probably spent his entire career craving praise from professionals without using tricks. Any explains as much to Dr. Sattler Haley wanted to make something that wasn't an illusion.

Dennis Nedry's clothing throughout the movie is extremely similar to some of the outfits used in The Goonies (1985) also produced by Steven Spielberg

During the lunch scene when Malcolmn begins to express his doubts, he does so with the light from the projector over his shoulder, (a luminary which represents what Hammond later on in the scene calls the light of discovery") As Malcolm moves through his arguments and pushes back harder and harder against Hammond, he sits farther back in his chair, slowly obscuring the light. By having made his scathing critique of "discovery" he has completely obstructed the light. The camera switches here to a slightly downward angle, which in turn causes the light to halo around his face. Those two things give him a divine appearance, as though he's the manifestation of some divine conscience chastising the impertinence of man.

B.D. Wong made his Broadway debut in M. Butterfuly, opposite John Lithgow. Lithgow and Jeff Goldblum appeared together in The Adventures of Buckaroo Banzai Across the Eighth Dimension. The film version was directed by David Cronenberg, who directed Goldlbum in The Fly.

A well built man clutching a bag is seen then he's disappeared,

In the book John Hammond is villanous and the main antagonist, while in the film is the Alpha Raptor.

Sam Neill, like Alan Grant, is also "not machine-compatible." He was apparently unable to figure out how to promote Jurassic World Dominion on social media and had to text Laura Dern for help.

The fate of the park itself is this when thinking about Jurassic World: Fallen Kingdom. Even if Nedry hadn't caused it to collapse, in twenty-five years time it would have been destroyed by the eruption anyway.

Gerald R. Molen: (at around 50 mins) The producer played Dr. Gerry Harding, the character who was out on the field with the sick triceratops.

Excision: Jeff Abel, better know as Canadian dubstep producer Excision, has a small cameo appearance.

Steven Spielberg: (at around 1 min) as the man with the beard at the beginning of the film watching the female raptor in the pin being unloaded.

Steven Spielberg: [signs] (at around 1h 21 mins) Using a sign with directions or instructions as a joke. In this case, the T. Rex's jaws filling the side-view mirror of the Jeep, with the mirror reading, "Objects in mirror are closer than they appear."

Steven Spielberg: [animation] (at around 25 mins) Mr DNA.

Steven Spielberg: [guns] Spielberg is an avid gun collector.

Steven Spielberg: [special effects from ILM] owned by his close friend George Lucas.

Steven Spielberg: [children in danger] Spielberg admits to a traumatic childhood.

Steven Spielberg: [desert] (at around 5 mins) The dinosaur dig in Montana.

Steven Spielberg: [characters or important events seen through the rear-view mirror of a car] (at around 1h 21 mins) Muldoon watching the T-Rex catch up to the car through the interior mirror.

Steven Spielberg: [dolly zoom] (at around 1h 40 mins) The camera zooms in on Ellie just as she's attacked by a Raptor in the maintenance shed.

Steven Spielberg: [flashlights] The torches in the film.

Steven Spielberg: [divorce] (at around 4 mins) this stems from Spielberg's own youth and his parents' breakup. Hammond's daughter is getting a divorce.

Steven Spielberg: [actors staring at something off-camera] (at around 20 mins) Grant, Ellie and Malcolm looking at the Brachiosaur when they first arrive on the island.

Steven Spielberg: [piano music during key scenes]

Steven Spielberg: inary people encountering the extraordinary]

Samuel L. Jackson was supposed to fly to Hawaii to film Arnold's death scene, but a hurricane destroyed the set, and the scene had to be scrapped. He regrets this, because he was physically chased by them and killed, and he really wanted to do it.

The original ending had a rib from the T. Rex skeleton skewer one of the Raptors, and the jaw drops and kills the other. But it seemed too phony, and the crew approached Steven Spielberg to come up with a better ending. They all pitched ideas, but Spielberg came up with the finale. He needed the T. Rex to be the star at the end.

Wayne Knight felt Nedry deserved to die, but it bothered him that it happened off-camera, and was not as gory as in the novel, where he was also decapitated.

In the shooting script, it was written that, during the Tyrannosaurus' escape (at around 1h 7 mins), Malcolm would simply get out of the SUV and run away, much as Gennaro had done moments before. In fact, this is how Malcolm behaves in the scene as written in the book. When the time came to film the scene, it was Jeff Goldblum's idea to make his flight more heroic, by having him distract the Tyrannosaurus so Grant could save the children.

In the original novel, John Hammond was killed by a flock of small dinosaurs called Procompsognathus (Compies), a species which does not appear in this movie. However, this death scene was resurrected and re-worked for another character in The Lost World: Jurassic Park (1997).

Ironically, despite Hammond's constant declarations of, "We've spared no expense," the park is undone entirely due to the expenses he did skimp on. Notably, leaving the security for masses of incredibly dangerous animals entirely in the hands of a single IT guy who is explicitly stated to have been the lowest bidder and has financial troubles of his own.

(at around 1h 14 mins) In "Return to Jurassic Park", the two hour making-of documentary released for Blu-ray, Steven Spielberg admits that the shot of the Barbasol can falling away from Nedry and being covered in mud was intentionally inserted to set-up a potential sequel. It was not until Michael Crichton's second book, "The Lost World", where Spielberg then realized the story would go in a different direction.

(at around 1h 7 mins) When shooting Gennaro's death, Phil Tippett wanted the camera tilted to see him get ripped to shreds. Although the budget couldn't cover it, Steven Spielberg liked the idea so much, he said they'd find the money.

The sound of the T. Rex killing Gennaro and a Gallimimus was Gary Rydstrom's Jack Russell terrier Buster shaking a rope toy in his mouth, recorded and slowed down, because he thought a T. Rex would sound just like that. Buster also provided the sound for the T-1000 eye-spiking a mental hospital guard in Terminator 2: Judgment Day (1991).

Nedry's reasons for betraying Hammond are clearer in the novel, who is misled, and never told anything about what goes on at Jurassic Park, forcing him to accept a bribe from a rival company.

In the novel, Donald Gennaro and John Hammond have completely opposite physical traits and personalities. Gennaro is a former football player (he actually manages to fight off a velociraptor, much smaller in the novel), and is a frank, sympathetic family man, who quickly copes with the situation, helping both Muldoon and Dr. Grant in time. On the contrary, Hammond is, in fact, the main antagonist of the book. He is portrayed as being very short, as well as cold, egotistical, hot tempered, and manipulative, using his grandchildren to soften Gennaro, and completely neglecting them when they go missing. In the end, he refuses to accept reality, making absurd plans about other parks, and getting killed by dinosaurs, while Gennaro survives the ordeal.

During Muldoon's death scene, as well as some of the kitchen scene, the Raptors were played by men in suits.

The ending, where the T. Rex saves the day, was added when Steven Spielberg decided that she was the hero of the movie.

(at around 1h 6 mins) The T. Rex, and the SUV it knocked over, were animated. The scene was shot bare, and then the T. Rex and the SUV were composited in later. It was the same for Gennaro's death. From the rear, it's a stand-in, but after the attack, its all CGI.

(at around 1h 45 mins) Sam Neill fumbled through several takes of giving Tim CPR, trying to avoid physical contact. Finally, with Joseph Mazzello's permission, he actually performed mouth to mouth. Mazzello now refers to this as his first on screen kiss.

(at around 1h 7 mins) Gennaro's Hail Mary before being killed was an idea Martin Ferrero stole from The Godfather Part II (1974). Another idea he had that didn't make it in was he wanted Gennaro to spray the T. Rex's face with pepper spray. You can see it hooked to his belt. Steven Spielberg thought it an interesting idea, but said no to it.

This movie cut out many species of dinosaur that were featured in the novel for budgetary and technological reasons. One of these was a small, chicken-sized dinosaur called Procompsognathids (Compies), which made an appearance in The Lost World: Jurassic Park (1997). Dr. Wu explains their reason for having this creature: Dinosaur excrement, he presumes, would have been bio-degradable during the Cenozoic era. However, in the modern day, bacteria have evolved to the point that it is no longer able to break down dinosaur waste, and the larger dinosaurs produce quite a lot of it. "Compies", as they are called, eat the other dinosaurs' waste and then excrete it themselves in smaller piles which are more easily broken down by present-day bacteria. The lack of Compies in the movie may explain the mountain of excrement that Ellie finds.

Body count: 5. The same as Jaws (1975).

In the original novel, the armed forces of Costa Rica play a key role in the end of the story, both rescuing and holding the surviving characters and bombing the island and the dinosaurs into oblivion. Filmmakers decided against this idea for budgetary reasons and to remain open the possibility of any sequels but, interestingly, this is also a mistake by author Michael Crichton himself, since Costa Rica hasn't had a military force since 1948.

In one of the first drafts of the script, the character of Ian Malcolm (Jeff Goldblum) was not included. Instead, the character of Donald Gennaro (Martin Ferrero) is injured in the scene where the T. Rex attacks the SUVs.

With every new draft of the script, there was a different set of survivors and a different set of characters dying. At various points during pre-production, Hammond, Malcolm, and Dr. Wu were going to die, and Gennaro and Muldoon were going to live.

(at around 1h 45 mins) In the movie, Dr. Grant resuscitates Tim after he is shocked by the electric fence. In the book, it is Lex who is the one resuscitated by Dr. Grant, after nearly drowning in a river escape.

All surviving characters from this movie appeared in a sequel. John Hammond, Lex Murphy, and Tim Murphy appeared in The Lost World: Jurassic Park (1997), Dr. Alan Grant and Dr. Ellie Sattler appeared in Jurassic Park III (2001), Dr. Henry Wu appeared in Jurassic World (2015) and Jurassic World: Fallen Kingdom (2018), and Dr. Ian Malcolm appeared in The Lost World: Jurassic Park (1997) and Jurassic World: Fallen Kingdom (2018). Alan Grant, Ellie Satler, Ian Malcolm, Henry Wu, and Dodgson all appear Jurassic World Dominion, though Dodgson is played by a different actor.

This movie is quite faithful to the novel, no doubt because of Michael Crichton's involvement with the screenplay. In fact, both are said to be thin on plot and characterization, but there are some differences. Alan and Ellie were never a couple in the book, and by the time of Jurassic Park III (2001), have gone their separate ways. Hammond has gone from a misguided fanatic to a kindly, but eccentric billionaire. Lex and Tim have swapped ages, are closer, and Tim is the computer hacker in the novel, while Lex is a petulant, useless character, but more capable in the movie. Grant becomes an uncomfortable surrogate father figure to Lex and Tim, who soften his attitude over the movie, no doubt Steven Spielberg's influence. Arnold, Muldoon, Gennaro, and Dr. Wu all have bigger roles in the book. The night vision goggles are put to more use in the novel. Aerial dinosaurs are not seen until the sequels, et cetera.

(at around 9 mins) In the movie, Alan Grant clearly states that he hates kids, and later in the movie develops a relationship with Lex and Tim after their adventure through the park. But in the book, Grant says that he loves kids, and watching their awed expressions at museums as they see dinosaur skeletons.

The "Big One" Velociraptor appears to kill only for fun or possible killing to get her revenge as she might understand to be lock up in a enclosure against her will, evident by the fact that she kills Robert Muldoon and soon afterwards hunts the rest of the humans. If she had killed and eaten Muldoon, who was nearly as big as she was, then she would have been full, and wouldn't have needed to hunt the other humans. There's an interesting line in The Lost World: Jurassic Park where the expedition's leader Peter Ludlow reassures the terrified group that "the rex just fed, so he won't be hunting for a while". While that's a callous way to refer to the man whose just been eaten alive, it's also entirely correct. Which makes the behavior of the Velociraptors in this movie quite curious. In the final act of the movie they kill Robert Muldoon and Ray Arnold - two fully grown adults who would likely feed a pack of Raptors for a number of days - yet continue to hunt Tim, Lex, Dr. Grant, and Dr. Sattler. While it's never stated on screen, this is because they're not hunting to eat, they're hunting for sport. One of the franchise's many hints at their intelligence. In the Jurassic World trilogy further explanations have been added. One is that the original raptors were more vicious because of the genetic splicing done to fill in DNA gaps, so they're not pure raptors, but hybrids. Additionally, because they're among the first they have no adult raptors to model behavior. And then, though Hammond makes a point of being present at the birth of the dinosaurs so they can "imprint" on him, it's clear he doesn't continue contact, making this yet another of his illusions about control. In contrast, in Jurassic World Owen raises and trains them from birth acting as their alpha. He also tells another character that animals born and raised in isolation (as Hammond's raptors are) makes them more antisocial, vicious, and destructive.

Although Malcolm is sidelined for the latter half of the movie, in the novel, he delivers most of his most memorable lines, while incapacitated due to his injuries (and being attended to by Dr. Sattler, and an increasingly agitated Hammond).

(at around 8 mins) When Grant is explaining to the kid at the dig site about a Velociraptors attack strategy, "They attack not from the front, but from the sides, from the other two raptors you didn't even know were there," and says "You're alive when they start to eat you," foreshadows Muldoon's death later (at around 1h 45 mins) when he is hunting the raptors and the big one attacks him from the side and eats him alive, as the other raptor in front of him creates a distraction. Paleontologists have since changed this view of raptors, but the Jurassic World movies have offered an explanation for the differences in that these raptors were actually hybrids due to the genetic splicing in filling in their code. In Jurassic World Dominion Alan Grant gives a callback to this scene stating that they used to think this was how raptors attack, but newer evidence suggested they do indeed go for the throat, like a lion.

No music was used during the first T. Rex scene or the Dilophosaurus scene. That also happened in Jaws (1975), another Steven Spielberg classic, when the last victim is eaten.

(at around 1h 40 mins) There is a scene in which Ellie is in the maintenance shed to reboot the power and finds Ray Arnold's bloody severed arm. This is similar to Steven Spielberg's Jaws (1975), in which the shark kills the man in the red rowboat, and the audience sees his bloody severed leg.

The Raptors seem far more interested in hunting the humans on the island. The only time they ever attack another dinosaur is when the T. Rex attacks them at the climax.

During the kitchen scene, the Raptors are outmaneuvered more than once, perhaps because they're outside their element, and are unfamiliar with a man-made environment, for example, the reflective surfaces they mistake for Lex. It's often the movie's most celebrated scene, at least whenever the T. Rex is not around.

One Raptor stalked Lex and Tim during the kitchen scene in the novel, not two.

For the original ending, Stan Winston wanted three-creature shots per day. As it was storyboarded, Grant starts working the controls of the condor and it starts moving; a Raptor emerges from the ducts; Grant moves the condor away but the Raptor leaps towards it and lands on it dangling from it with the crane moving forward towards the dinosaur skeleton's tail breaking it off and a Rex leg; one of the Raptors tries to get into the lift cage so Grant works the controls back and forth, smashing the Raptor into the Rex jaws; some of the buckles come loose; the Raptor smashes into the other skeleton, a Brachiosaur; the Raptor thrashes and Grant tells everyone to hold on; the lift crashes down on the Raptor and it screams; blood runs beneath the condor; Alan, Ellie, (a younger) Lex and Tim watch all this as the Raptor dies; they see the other Raptor attack, but (a younger) Hammond shoots it and waves them to the exit.

(at around 1h 6 mins) When the Tyrannosaurus breaks through the glass ceiling window of the Ford Explorer to try and get the kids is similar to Steven Spielberg's Jaws (1975) when the shark attacks Hooper in the anti-shark cage underwater to try and eat him, ultimately failing.

Early designs for the park, had a bridge over water, between the Visitors Center and the big doors (which can be seen in Jurassic World (2015)); Lex outside the Explorer, when the T. Rex attacked it; a scene with Grant, Lex, and Tim in a raft, being attacked by a dinosaur; the T. Rex chasing Grant, Lex, and Tim through the jungle, with the kids' ages swapped; three Raptors attacking at the Visitors Center, et cetera.

According to storyboards, the first scene with the T. Rex played out like this: the kids were in the Explorer, with a character called Regis who showed Tim the goggles. Grant had glasses and a beard (like in the novel) and had Gennaro as a passenger. Lex was kicking her legs over the front seat and Tim stopped her when he heard the T. Rex, and he still had the goggles on. Gennaro had more hair. Lex looks at the roof before the leg lands on it, with the chain still attached. A shot of the Explorer from the T. Rex's side of the fence. Tim sees the T. Rex touching the fence through the goggles. The danger sign also lands on the roof. When the T. Rex first steps out onto the road, its foot hits the ground. A POV shot of Tim watching the T. Rex circle the other Explorer. The T. Rex eyeing Grant and Gennaro through the Explorer, and Grant using a radio to warn the kids not to move. Tim and Lex looking up at the T. Rex through the roof as it looks in at them. A wider shot of the T. Rex attacking the roof. Tim and Lex crawling through the mud. The T. Rex watching Grant wave the flare from her POV. Gennaro runs from the Explorer, but doesn't wave a flare like Malcolm. The T. Rex gives chase, knocking Grant out of the way. Tim is unconscious in the Explorer, and then tries to get free. The T. Rex looks in at Tim with a mouth full of mud, et cetera.

The Franchi SPAS-12 shotguns used by Robert Muldoon and Alan Grant in the movie have the first generation stock option. The first generation shotgun stock was designed so that a spring loaded stud mounted on the interior of the stock locked into the rear sight. By pulling this stud rearward it clears the sight and the stock can be unfolded. Muldoon can clearly be seen depressing this stud when he is hunting the Velociraptors moments before his famous "clever girl" last words.

According to the storyboards, the kitchen scene plays out with an angle from above when Lex and Tim first enter the kitchen; Tim turns the lights off, not Lex; Lex and Tim look at the door; another shot with Lex and Tim watching; Lex holds onto the ladle after tapping it; Lex looking at the Raptors' reflections; an image of Lex hiding and the Raptor hitting the cabinet; the other Raptor seeing Tim run; Tim's feet slipping; Tim by the door as the Raptor slips; Tim crawls out the door, et cetera.

The song that plays in the Costa African restaurant where Nedry meets Dodgson, is called Las Gaviotas. Among the lyrics are "no cabe duda que eres infiel. Amas el oro, amas la plata. Eres amiga del interes" (no doubt you're unfaithful. You love gold. You love silver. You're a friend of interest.) The lyrics parallel/foreshadow Nedry's actions which lead to the destruction of the park.

There seems to be a color code to a character's chance of survival. All of the main characters who survive are colorful in their costumes (Alan Grant wears blue, Ellie Satler wears pink and blue, Ian Malcolm wears black, and John Hammond wears white). Meanwhile, the characters who die all wear very bland colors (Gennaro wears brown and white, Nedry wears gray blue and brown, Arnold wears striped off-white and Muldoon wears brown). Tim and Lex wear a combination of colors and browns; they survive, but arguably go through the worst attacks.

In a storyboarded but unused scene, Lex walks towards Grant and Tim, when a baby Trike appears behind her; it knocks her, sending Lex flying; Lex turns and sees the Trike.

The T. Rex versus Raptor battle was not the originally planned finale.

In storyboards, the second scene with the T. Rex, plays out with Muldoon, who has a mustache; Muldoon and Ellie are back in the Jeep already with Malcolm when the T. Rex attacks; more dialogue with Muldoon saying they'll find Grant, Lex, and Tim when the motion sensors are working again, just as Malcolm hears the T. Rex.
