(at around 1h 50 mins) The Japanese tourists running from the rampaging T-Rex in the San Diego scene (an obvious homage to the "Godzilla" movies) are saying in Japanese: "I left Japan to get away from this!"
Julianne Moore admitted that she did this movie to pay off a divorce settlement, and to work with Steven Spielberg.
The two models of the T-Rex each weighed nine tons. Due to their weight, the crew constructed sets around them, rather than moving them onto sets.
This movie held the record for the biggest opening weekend in history from May 1997 until November 2001, when it was surpassed by Harry Potter and the Sorcerer's Stone (2001).
There is roughly fifty percent more dinosaur action in this movie than in Jurassic Park (1993).
Writer David Koepp said that when he was writing the script to this movie, he taped a fan letter next to his computer screen. The letter was from a viewer of Jurassic Park (1993) who complained he "waited too long" to show the dinosaurs in that movie.
Director Steven Spielberg had to attend an early screening for Swingers (1996) in order to give approval for the use of the Jaws (1975) theme. He was so impressed by Vince Vaughn that he offered him a part in this movie.
It's curious that Roland wishes to hunt the male/buck Tyrannosaurus, when the female is actually larger. This could possibly stem from the fact that Roland is a professional hunter, and in sport hunting, it is the male that is usually prized for its size and adornment. Roland may not have known that it is the female that holds the size.
Initially, Steven Spielberg wanted to save the San Diego sequence for a third movie. However, he later decided to include it in this movie after realizing that he would probably not direct another installment in the franchise.
After the twin hits of Jurassic Park (1993) and Schindler's List (1993), Steven Spielberg took a rare sabbatical, and didn't return to the director's chair until this movie.
The title of the novel was simply "The Lost World", with the cover showing the familiar Jurassic Park logo to establish it as a sequel. However, the studio feared that the public might confuse it with the Sir Arthur Conan Doyle classic of the same title (the title and many plot elements were indeed deliberate references by Michael Crichton), and originally considered naming this movie "The Lost Island". In the end, the novel's title was kept, but "Jurassic Park" was appended to solidify the sequel connection.
In early drafts of the script, Lex (Ariana Richards) and Tim (Joseph Mazzello) were kept in for much longer. Some even had the kids going back to the park and encountering the dinosaurs again.
There was a special gadget developed for the movie: strobe lights in the theatre. Theatres had to install strobe lights on the walls. The projectionists had to put some metal-markers on the film itself whenever there was a flash in the movie, that triggered the lights in the audience. The problem: there isn't a single flash in the whole movie. So after having installed the very expensive system, there was actually no "correct" moment to put the markers. In their despair, they put the markers somewhere during the storm-scenes. That resulted in either a cascade of strobes or almost none at all, so it was a different experience for watching it in different theaters. The audience was warned in advance, that there were strobe lights in the performance.
Like Jurassic Park (1993), this shoot finished before the scheduled seventy-four days. It was completed in sixty-nine days.
Joe Johnston lobbied for the director's job, but schedule problems during the post-production of Jumanji (1995) forced him out. Steven Spielberg was also adamant to direct this sequel himself, promising Johnston the director's chair for the third movie, which he directed.
Steven Spielberg confessed that during production he became increasingly disenchanted with this movie, admitting, "I beat myself up, growing more and more impatient with myself. It made me wistful about doing a talking picture, because sometimes I got the feeling I was just making this big silent-roar movie. I found myself saying, 'Is that all there is? It's not enough for me.'"
Although Lewis Dodgson had a bigger role in the book sequel The Lost World, compared to his one scene appearance in Jurassic Park (1993), Steven Spielberg dropped the character from this movie.
(at around 2h) The closing scene, a view of the dinosaurs living undisturbed on the island, includes pterosaurs. They were considered for action sequences in both of the first two movies, but these were abandoned, making this brief clip their first on-screen appearance. They featured prominently in the first novel, in a sequence that took place in a pterosaur aviary. This was finally realized in Jurassic Park III (2001), and revisited in Jurassic World (2015).
Steven Spielberg and John Williams felt that the score of this movie needed to be slightly different to that heard in Jurassic Park (1993). Because it was a remote island chain, they added drums and bongos.
The vocalizations for the juvenile tyrannosaurus were of a baby camel crying for its mother.
If you look closely, the face of the male Tyrannosaurus is adorned with many facial scars, and many of the teeth in his mouth are missing or broken. This is indicative towards the Rex participating in fights for mating rights or dominance.
The S.S. Venture, which transports the Tyrannosaurus to San Diego, is a reference to King Kong (1933), who was transported to New York City on a ship called the S.S. Venture. This is the franchise's second reference to the classic movie, the gate in the first movie was modelled on the Skull Island gate, with Dr. Ian Malcolm pointing this out.
(at around 40 mins) Robert Burke's quote referring to the Compsognathus (Compys), "there haven't been any visitors on this island, there's no reason for it to fear man" is taken directly from the Lost World novel, except it's said by Ian Malcolm.
The five islands in Las Cinco Muertes are: Isla Matanceros, Isla Muerte, Isla Sorna, Isla Tacano, and Isla Peña. Isla Nublar from Jurassic Park (1993), Jurassic World (2015), and Jurassic World: Fallen Kingdom (2018) is not a part of this island chain.
As of 2016, this is the only sequel that Steven Spielberg has directed that is not related to the Indiana Jones film franchise.
(at around 1h 10 mins) Roland Tembo (Pete Postlethwaite) refers to the Tyrannosaurus Rex as "the greatest predator that ever lived". While the Jurassic Park movies depict the T-Rex as an active hunter, the question whether the T-Rex was a predator or a poacher/scavenger has been (and still is) the subject of a decades-long debate. Opponents of the predator theory maintain that a T-Rex's arms were too short to hold down a prey, and that it would not have been able to run as fast as its prey due to its bulk. Additionally, its excellent sense of smell would serve to sniff already dead prey over large distances. Supporters of the predator theory point at the fact that T-Rexes had depth perception, a trait seen mainly in predators, so that they can estimate the distance to their prey. Also, fossilized skeletons of other dinosaurs have been found with healed bite marks from T-Rexes on them, which would indicate that a T-Rex had hunted them while they were alive, rather than dead.
Some scenes were shot in the redwood forests of California, the same location as Star Wars: Episode VI - Return of the Jedi (1983).
(at around 1h 45 mins) The T-Rex can be seen scratching its head in a direct homage to the stop motion T-Rex scratching its head in King Kong (1933), one of Steven Spielberg's favorite movies growing up.
Thirteen stunt performers worked on Jurassic Park (1993), while fifty were used for this movie.
While at his vacation home in the Hamptons for the Fourth of July, director Steven Spielberg suddenly saw an image in his mind of a boy looking out of his bedroom to see a T. Rex drinking from the family swimming pool. Prompted by the image he saw, Spielberg changed the ending to what is seen in the completed movie, and included the image he saw as the scene where the buck approaches the house of young Benjamin and his family.
Jeff Goldblum received a W163 for free from Mercedes-Benz as a result of the tie-in. As of 2011, it is used as his personal vehicle.
The reason for Stegosaurus being in this movie was because director Steven Spielberg received "literally thousands" of letters, many of which came from children, inquiring why stegosaurus was absent in the first movie. Conceptual artist for the first three movies, Mark 'Crash' McCreery had previously expressed in the Jurassic Park Topps trading cards his regret that stegosaurus was not among the dinosaurs that appeared in Jurassic Park (1993). As Colin Wilson recalled, "Steven made that his mission, to come up with a really good stegosaurus sequence". Two animatronic stegosauruses were created for the movie, one was an adult whose maquettes and animatronic were created by a five-person team headed by Mark Maitre and Scott Stoddard, with Alfred Sousa and Kirk Skodis being in charge of the mechanical armature of the animatronic. Of the animatronic, John Rosengrant stated, "From the top of its spiny plates, it was about sixteen feet tall, and almost twenty-six feet in length." It was, at the time, the second largest creature Stan Winston Studio had built. The second animatronic was the juvenile stegosaurus "Claire", whose animatronic was sculpted and painted by David Grasso and mechanized by Bob Mano. It was eight feet long and four feet tall. Cinefex issue #70 revealed that the scale of the Stegosaurus was determined on a shot-by-shot basis, guided more by dramatic requirements than a commitment to scientific fact. Some shots of the dinosaur showed it reaching a length as long as forty-six feet.
Gary Oldman was offered the role of Peter Ludlow, but turned it down due to scheduling conflicts. He was replaced by Arliss Howard.
The screech the Pteranodon makes at the end was made by Gary Rydstrom slowing down the sound of him taking out tooth floss from his box.
(at around 1h 50 mins) After the bus crashes into the video store, a fictional Tom Hanks movie "Tsunami Sunrise" can be seen on a cardboard stand-up.
(at around 1h 25 mins) The scene where the female Tyrannosaurus pokes her head through the waterfall to find the humans that are hiding from her and licks Sarah Harding is taken from the chapter "Tyrannosaur" of the Jurassic Park novel when Rexy does the same to Tim Murphy. This scene was originally planned to be in the first movie, but was never used.
(at around 1h 50 mins) When the bus crashes into the video store, there is a poster of the Robin Williams film Jack (1996) that had been adapted to Jack and The Beanstalk. This is in the same shot as Arnold Schwarzenegger's King Lear poster.
In 1995, director Steven Spielberg met Vanessa Chester at the premiere of A Little Princess (1995), in which she appeared. Chester later recalled, "As I was signing an autograph for him, he told me one day he'd put me in a film." Spielberg met with Chester the following year to discuss this movie before ultimately casting her as Malcolm's daughter, Kelly.
(at around 7 mins) Dr. Malcolm accuses Peter Ludlow in the mansion of lying about the facts surrounding the deaths of three people during the course of events in Jurassic Park (1993). In fact, four people died in the first movie: Ray Arnold (Samuel L. Jackson), Robert Muldoon (Bob Peck), Donald Gennaro (Martin Ferrero), and Dennis Nedry (Wayne Knight); five if you include the worker at the beginning who is killed by the velociraptor. However, the worker's death already occurred before the main events of the first movie (it was the reason why a team of experts was sent to Jurassic Park in the first place), so Ludlow could not have lied about it. None of the characters could have known of Nedry's fate since he absconded with the embryos early on, and his death was not witnessed, so his status is most likely "missing, presumed dead".
(at around 1h 50 mins) A movie poster in the video store appears to be Arnold Schwarzenegger as King Lear. This is a reference to Last Action Hero (1993), which was released when Jurassic Park (1993) was in theaters and was expected to be a competing blockbuster.
In the book, Sarah was an animal behaviorologist, not a paleontologist; the paleontologist who Malcolm went to Isla Sorna to save was a man named Richard Levine, a character who only made it to this movie as certain aspects of Sarah's character.
Ian Malcolm (Jeff Goldblum) and Dr. Sarah Harding (Julianne Moore) are in a relationship. This is a contrast to the novel, in which Malcolm and Sarah are former partners who have remained platonic friends (Sarah seeking out Malcolm after the events of Jurassic Park (1993)). In the novel, Kelly isn't Malcolm's daughter, and she goes to the island with her friend R.B. to help find their idol and school professor Dr. Levine. Also, in the novel, Kelly is white, while her friend Arby is black. The character of Eddie is also a stark contrast to the novel. In the novel, he's a younger man with a full head of dark hair who is killed by the velociraptors.
Originally, Dr. Ian Malcolm's team included a fifth member, a paleontologist named Dr. Juttson. He was inspired by the character Richard Levine from the novel. Dr. Juttson was dropped due to an already overcrowded cast, and most of his lines were given to Dr. Sarah Harding.
Part of the promotion for this movie included a website, which visitors could explore to find out facts about the film's production. One page included John Hammond's office. If users found a hidden password they could access Hammond's computer and InGen files. For the user name Hammonj, one of the passwords was Gandhi, a reference to Sir Richard Attenborough having directed Gandhi (1982).
Several scenes were deleted from the theatrical cut. Two are included as special features on the DVD and Blu-ray: Peter Ludlow talking to the InGen committee, and Roland and Ajay talking in a Mombasa bar. A shot of Sarah running from the Stegosaurs saying "Isn't it great?" with Malcolm, Nick, and Eddie was cut, but can be seen in the trailer. Much more footage is on the cutting room floor, but has not yet been made available outside of stills, adaptations, and scripts: More footage of Malcolm, Nick, and Eddie arriving on the island and setting up base-camp; more dialogue with Sarah and Malcolm on their way back to base-camp, adding background about the time between the films and their relationship; Ludlow drunkenly stumbling and breaking the baby Rex's leg (this deleted scene explains why there is a bottle next to the baby rex when Nick Van Owen runs to the baby); Kelly telling Malcolm he should marry Sarah. Certain puppets and animatronics created by Stan Winston during filming were later omitted, including several Velociraptors (whose tiger-stripes were far more visible in stills than in the finished movie). Scenes such as Pteranodons attacking the helicopter and a Rex attack on the High Hide were developed, but never filmed.
Jeff Goldblum hosted Saturday Night Live (1975) to promote this movie. Four years earlier, he had hosted a few months after Jurassic Park (1993) had opened. That appearance also included a brief appearance by castmate Laura Dern, with whom Goldblum was romantically involved at the time.
In the script, Robert Burke claims to have seen the remains of an ankylosaur herd while he was in the helicopter that transported him to Isla Sorna, and Burke further claims that they have gone extinct once again.
As a thank-you to Steven Spielberg, Industrial Light & Magic created an animation that features a pack of Compsognathus (Compys) tap dancing wearing bow ties, top hats, and holding canes. It was included in Beyond Jurassic Park (2001) and on The Lost World: Jurassic Park (1997) Blu-ray.
Steven Spielberg originally approached Juliette Binoche about playing the role of Sarah Harding. She supposedly replied that she would appear in the movie only if she could "play the dinosaur". The part went to Julianne Moore instead. Binoche had previously declined the part of Dr. Sattler in Jurassic Park (1993).
(at around 1h 18 mins) Carter's (Thomas Rosales Jr.'s) famous words, "ten, fifteen minutes" when asked when he last saw Dieter (Peter Stormare) were taken from a security guard who worked at Jurassic Park in the first novel.
The fate of Benjamin and his parents are revealed in one of the final drafts of the script, they survive: "The tyrannosaur hears the the screams and turns its head sharply. Something in the mother's wail rings a bell with it too--it sounds like its baby's cries did; back on the island, they are scrambling to get out the door when the Tyrannosaur head crashes through the wall; they all freeze, terrified, stuck in the doorway, as the head pokes in, looks around, takes a few good sniffs to scent them all-- and then withdraws, leaving a large gaping hole in the side of the house. Benjamin's Mom and Dad are paralyzed with fear, but Benjamin runs forward, to the edge of the hole for one last look and sees the Tyrannosaur lumber across the backyard, tripping motion sensor lights and enraging house pets as it goes."
(at around 12 mins) Malcolm remarks that Hammond went from "capitalist to naturalist in four years." Sir Richard Attenborough's brother is naturalist Sir David Attenborough.
Steven Spielberg originally intended to just produce this movie rather than direct.
(at around 1h 10 mins) The alpinist Roland Tembo (Pete Postlethwaite) mentions as the first man to climb the Mt. Everest without oxygen bottles is Reinhold Messner.
The gun Roland Tembo (Pete Postlethwaite) wields is a double-barrelled rifle chambered in .600 Nitro Express. B. Searcy & Co., of Boron, California custom-made two rifles for this movie at a total cost of $100. Director Steven Spielberg kept one for his private collection. He has said that he almost never fires it because it hurts his shoulder.
(at around 1h 23 mins) When the male T-Rex is poking its head in Sarah's tent, and Carter (Thomas Rosales Jr.) screams at the sight of the T-Rex, alarming the group, he is screaming "Matalo!" repeatedly, meaning "Kill him!" in Spanish.
The cliffside set was built onto the side of a parking building at Universal Studios, Hollywood.
Composer John Williams modified the original Jurassic Park themes for this movie to include homages to Max Steiner's score from King Kong (1933).
An alternate opening was for a Japanese fishing boat to pull up a Parasaurolophus carcass in its net, then the net breaks from the weight of the carcass and disappears into the water below. Paul Mejias supervised the construction of the sculpture and even though this alternate opening scene never made the final cut, the carcass was still used in the film in the scenes taking place in the Tyrannosaurus nest and the boneyard.
Michael Crichton named the title after Sir Arthur Conan Doyle's book of the same name.
(at around 41 mins) It was mentioned that the juvenile T. Rex was a couple of weeks old. It would have been too long for it to be that old, although it's implied that InGen accelerated the growth of their dinosaurs, which could account for the issue.
Steven Spielberg wanted to work with Indian actor M.R. Gopakumar in the movie, but due to his passport travelling issues, he was unable to accept that offer.
Pteranodons were ultimately chosen instead of the novel's Cearadactylus probably because of its larger size, more spectacular and impressive appearance and massive popularity with audiences.
(at around 1h 45 mins) After the male Tyrannosaurus escapes, an InGen guard explains that the animal had been tranquilized with two darts loaded with concentrated carfentanil, ten milligrams worth of it. Sarah said that that should have put the Tyrannosaurus into a coma, but it would have done more than that, it should have killed the Tyrannosaurus. Carfentanil is one of the most potent opiates in existence, it is approximately ten thousand times more potent than Morphine. Carfentanil is mainly just used for sedating rhinos and elephants. A Tyrannosaurus and an African Elephant have roughly the same mass, so the dosage used on a T-Rex would be the same as for an Elephant, which would be between one half and one milligram. Pumping ten milligrams of Carfentanil into the T-Rex would be the same as injecting it with about one hundred fifty milligrams of Morphine, which is about ten times the dosage needed to sedate an animal the size of a Tyrannosaurus.
In one of the many jungle scenes, you can clearly hear the distinct calls of a Kookaburra, a bird which is native to Australia. However, this movie was set off the coast of Central America.
Both Stegosaurus animatronics were transported to Prairie Creek Redwoods State Park in California for the filming of the stegosaurus skirmish.The juvenile animatronic was the only practical Stegosaur that was filmed as Steven Spielberg, Stan Winston, and stunt coordinator Gary Hymes agreed that stunts with the adult Stegosaurus animatronic would be potentially dangerous, particularly because of its spiked tail, and filming with the adult was rescheduled for one of the stages of Universal Studios, feeling these stunts would be safer inside a controlled environment. ultimately, almost all the shots of the adult stegosaurus were created with CGI, with the animatronic only being used in close-up shots, such as the caged stegosaurus that Nick and Sarah approach when infiltrating the camp of the InGen hunters.
Roland claims to have "seen" parts of Isla Sorna before the events of the movie, suggesting he was very widely travelled and had toured the island many years before the dinosaurs were bred there.
Despite being a popular dinosaur and appearing in the first four movies, Triceratops is seen only for a short time in the sequels. It only appeared for a minute in this movie, and a few seconds in Jurassic Park III (2001). However, Jurassic World (2015) broke this trend.
The paleontologist "Dr. Burke" is an affectionate caricature of real-life paleontologist Robert Bakker.
(at around 1h 25 mins) The waterfall scene shows Sarah getting licked by the female T. Rex. Researchers compared fossilized hyoid bones (a horseshoe-shaped bone that anchors the tongue, and supports the opening into your lungs) with those of crocodiles and birds, the closest living relatives to dinosaurs. The study led to some unexpected outcomes, mainly, that most depictions of dinosaur tongues in popular culture are wrong. For some reason (maybe because Tyrannosaurus translates to "tyrant lizard" in Greek), many drawings show dinosaurs with long, lizard-like tongues. But this new research reveals most actually had tongues similar to crocodiles, flat and rooted to the bottom of the mouth. "The surprising part we found was that most dinosaur hyoid bones are pretty boring", says Julia Clarke, a paleontologist and co-author of the study published this week in PLOS One. "The evidence really argues for simple, limited tongue movement in most dinosaurs." According to Clarke's research, there are many more tales an ancient tongue bone can tell, like the origin of flight. Unlike the stubby, simple hyoid bone seen in dinosaurs like the T. Rex, researchers found a much more complex structure in pterosaurs, bird-like dinosaurs, or "winged lizards". "We wanted to know when this crazy evolvement of tongues from bones happened", Clarke says. "Only after the origin of flight (in vertebrates) do you get these Olympians of the bony tongue movement." Noting the same structure in pterosaurs, researchers say it's likely the evolution of the bony tongue and flying are connected. When arms evolved into wings, flying dinosaurs lost the ability to snatch up prey. Clarke says these advanced tongues could have served as a new means to procure food, a feature also seen in modern day birds. A T. Rex tongue is definitely not comparable to our own puny, pink pokers, but it is similar in its construction, made not of bone, but thick tissue and muscle. Because its hyoid bone is basically two short rods that sit way back in the throat, the tongue was moored to the bottom of the mouth, making it impossible to fling it free like the flexible, bony tongue of a bird. There was one oddity in the study Clarke couldn't explain. Armored dinosaurs, like a stegosaurus or ankylosaurus, also had complex hyoids, even though they were very different animals than winged dinosaurs. Clarke says she's also unsure what purpose the rooted tongue of a T. Rex would have served, but based on observations of crocodiles, which have a similar simple hyoid bone, it had something to do with food. A flat tongue certainly makes sense for a crocodile, which swallows prey whole, a long, bony tongue would probably interfere with that, or maybe the tongue was always meant to be a landing strip for the bright, blue birds that pick leftover meat out of crocs' teeth. Either way, tongues can tell us a lot more than we thought.
This movie saw the introduction of male Raptors with a different color scheme than those of the ones before, and the female seen in the movie. Stan Winston explained the reasoning behind the new color schemes of the Raptors and other dinosaurs by saying "we had to design new paint schemes not only for the new dinosaurs, but for some of the already designed dinosaurs from the last movie, because now there were male dinosaurs, as well as females, and typically in nature, the males of any species are far more brightly colored. We also wanted to make sure the audience would be able to tell the males and females apart." The final coloration that was chosen for the male velociraptor was a tiger-like color scheme devised by Christopher Swift.
(at around 4 mins) If you listen closely when Paul and the crew run to help Cathy you can hear Paul say "Get away from my daughter!" although the line does not appear in the subtitles.
For the vocalizations of the male Tyrannosaurus, pigs and "weird Costa Rican mammals", mammals that Gary Rydstrom and his team recorded, but never knew what their identities were, had a similar screech like the baby elephant used for the females and were used in place of the latter. The original Tyrannosaurus roars from Jurassic Park (1993) were also re-used for the female Tyrannosaurus.
Initially, three Mercedes ML-320s were modified for the trip to Isla Sorna. The third SUV, built as a "mobile observatory", is currently on display at the Mercedes-Benz museum in Stuttgart, Germany.
Compsognathus was nicknamed "Compys" by Stan Winston's crew, visual effects supervisor Dennis Muren considered them the most complex digital dinosaur, given their small size meant the Compys had their whole body visible, and thus needed a higher sense of gravity and weight.
In the novel, it's revealed what happened to Cathy Bowman, the little girl, but in the novel her name was Christina L. Bowman. She gets bitten by an escaped procompsognathus (Compys) (which she thought was a harmless lizard) ultimately suffering an allergic reaction, but she gets treated by a doctor named Cruz in Puntarenas and survives. She then describes the lizard to a Doctor Marty Guitierrez, and he later finds the remains of the procompsognathus and sends them to a lab in Amaloya to be identified, ultimately getting a fax from the Columbia medical center tropical diseases laboratory finding that the lizard-procompsognathus blood is mildy reactive to an Indian King Cobra.
The game trail was filmed completely on-location in Northern California near the Redwoods State Park, shots of the trail were split between two locations: Patrick's Point State Park, and a private ranch in Fieldbrook. The sequence starts in Patrick's Point on a road, before splicing the private ranch for the opening shot of the trail itself. to increase the perceived size of the ranch, The InGen vehicles were driven in large circles to give the impression that the location was larger than it really was, shots taken of Ian Malcolm's team atop a rocky outcrop were again taken at Patrick's Point State Park, on Ceremonial Rock. The scene then continues on the private ranch to its close.
(at around 40 mins) When Dr. Robert Burke (Thomas F. Duffy) encounters Dieter Stark (Peter Stormare) with a Compsognathus (Compy) during the capture of the dinosaurs on the Game Trail, he identifies it as "Compsognathus Triassicus". There is no such species of Compsognathus known by this name. It was a combination of the genus Compsognathus and the species Procompsognathus Triassicus, though this is merely an error by the scriptwriters. It is unknown if there is a species called "Compsognathus Triassicus" in the movie canon, or if it was simply an error that Dr. Burke made. Despite the possibility that the movie's Compys are actually Procompsognathus, Paleontologist and consultant for the movies, Dr. Jack Horner said in the past that they were indeed Compsognathus.
Screenwriter David Koepp took the names Roland and Van Owen from a favorite song of his sung by Warren Zevon called "Roland the Headless Thompson Gunner".
The baby T. Rex had two different practical versions, a "fully contained" remote controlled version the actors and actress could carry, and a hybrid operated by hydraulics and cables which lay on the operating table, and had the added complexity of moving as Vince Vaughn held its head.
This movie is one of Camilla Belle's earliest acting roles. In it, she has the small role of Cathy Bowman, the little girl who is attacked by a group of Procompsognathuses (Compys) early on.
In the script, instead of the Parasaurolophus "Elvis", Dieter Stark captures a Corythosaurus (misspelled "Carninthosaur" in the script) though this scene was cut from the final movie, it is included in Mighty Chronicles adaptation of this movie. This early design choice is also referenced in the movie with Roland carrying a factsheet of Corythosaurus, and even misidentifies the Parasaurolophus as a corythosaur.
The San Diego incident also references the movies Gorgo (1961) and Gappa the Triphibian Monsters (1967), in which a large creature wrecks havoc in a city while looking for their stolen offspring.
(at around 1h 23 mins) When the male and female Tyrannosauruses attack the camp, Malcolm unsuccessfully tries telling the mercenaries, "don't move, don't run," which is similar to what Grant said to him in Jurassic Park (1993) about how the T. Rex's "vision is based on movement."
The spikes on the end of the Stegasaurus tail is called a Thagomizer. The arrangement of spikes had no distinct name until a 1982 "Far Side" cartoon by Gary Larson coined the term.
Sarah repeatedly fails to heed her own advice. She chastises the others in her group about the importance of observing without interacting shortly after almost getting herself killed attempting to pet an infant stegosaurus, which was part of the stegosaurus herd who she was documenting in their natural habitats. She chastises Nick for his terrible idea to bring the infant Tyrannosaurus back to the trailer, but then helps him do it. After this inevitably ends in disaster, she proceeded to explain the dangers of the male and female Tyrannosaurus' tracking the group with their powerful olfactory cavities, but she still wears her jacket coated in the infant's blood as she has a bad habit telling off others for things she then proceeds to do anyway.
Art Malik turned down the role of Ajay because he thought the role was too small, and felt the fee he was being offered was insulting.
Unlike the movie, in the novel, the RV goes over the cliff, not the trailer it pulls. In reality, it would not be likely that the second trailer could hold the weight of the first trailer; once the engine went over, the rest would easily be pulled over. However, it is possible that the first trailer was much, much lighter than an average RV, due to its electric engine, lightly built design. Also, Eddie goes through the first trailer with a rope to send down to Ian, Sarah, and Nick. However, he travels through the accordion-connector, which is essentially impossible. When the second trailer is flipped by the rexes, the connector would be twisted shut like in the novel, yet Carr is able to easily climb through the passage and toss the rope down.
(at around 1h 13 mins) It is thought that if Stark only needed to urinate, then he could of done less privately. In fact, he goes deeper into the jungle, as you actually see him pull a wrap of drugs from his pants.
(at around 35 mins) Roland refers to a pachyceplosaurus as "Friar Tuck", coincidentally Pete Postlethwaite played a monk/friar "Brother Gilbert" in DragonHeart (1996).
(at around 22 mins) When they find Sarah's "lucky pack" on Isla Sorna and start calling out for her, Nick calls out her full name, "Sarah Harding", to which Ian sarcastically says how many Sarah's are on this island. Ironically, near the end when they're looking for Nick in the worker village (at around 1h 30 mins), Malcolm calls out to him by his full name, "Nick Van Owen".
In a conversation between Sarah and Dr. Burke about the Tyrannosaurus tracking them, Sarah explains that the Tyrannosaurus has an olfactory sense of smell second only to the turkey vulture, which will allow them to track the humans across the island to address the perceived threat to their offspring, the Tyrannosaurus' established sense of smell allows the male and female to find them shortly thereafter, once the male Tyrannosaurus pokes its head into Sarah and Kelly's tent, it can't find them so long as they remain perfectly still, the scent they've been following was the infant blood on Sarah's jacket, which was hanging over their heads, which is masking their scent, allowing them an opportunity to escape and survive.
The sounds of the Pachycephalosaurus consisted of several vocalizations with some sounding much aggressive or ominously threatening, the vocals are portrayed as raspy or blunt consisting of squawks or bleats from both vultures, sheep, goats, and moans from a camel and rhino.
The first dinosaur the heroes encounter on the island is a Stegosaurus, which did not appear in the original novel. In the first novel, the visitors see a sick stegosaurus, but this was changed to a Triceratops for the movie.
There's concept art that exists for this movie that depicts a T. Rex with a brownish skin color in a cage being hauled away, though the Industrial Light & Magic website states that the concept art is for the first movie, the concept art can be proven to actually come from this movie due to the bottom right corner of the artwork having the words "Lost World", and because the T. Rex in the concept art is in a cage, but is brown instead of green like the male T. Rex, who is captured in this movie, this could suggest that the female T. Rex was originally going to be the T. Rex brought to San Diego instead of the male, or that both Tyrannosauruses were to be captured.
Each version of the M-Class Benz in the movie had two copies, each painted exactly as the other.
The motorcycles used by the InGen hunters during the dinosaur herding scene were the Italian-made Cagiva Canyon 500s.
In the digital storyboards by Stefan Dechant the male was depicted as either yellow and gray or as the same color as the female. John Rosengrant later devised the green color scheme for the male. One such concept by Rosengrant was a colored version of the 1991 T. Rex concept art for Jurassic Park (1993). Another color scheme applied to this same concept art would be widely used in promotional material for this movie. Even though the buck was given a different skin color to differentiate it from the female, Stan Winston Studio was concerned that this would be difficult to see in low-light conditions. So Shane Mahan began to manipulate images of the T. Rex from the first movie, creating a series of eight head designs that he sent to Director Steven Spielberg. The design chosen by Spielberg featured larger brows, a scarred face, and a neck wattle.
Roland is the second person to come from Kenya (technically Mombasa). The first was Robert Muldoon, the game warden from Jurassic Park (1993) also came from Kenya.
Julianne Moore was in The Fugitive (1993) the same year Jurassic Park (1993) was released. Steven Spielberg was impressed with her small role in the movie. He interviewed her for the part and cast her in the part of Sarah Harding in this movie.
Due to a recent discovery of specimens of juvenile T. Rexes, it is possible that infant T. Rexes actually had longer skulls, therefore making the infant T. Rex in this movie unrealistic. However, the dinosaurs in the Jurassic Park novels and movies were genetically engineered by splicing together DNA from several different sources, as was explained in the first book and movie. Therefore, the appearances of all of the dinosaurs, would be dependent upon their respective genetic make-up.
Camilla Belle (Cathy Bowman) and Vanessa Chester (Kelly) appeared in A Little Princess (1995).
Malcolm's personality seemed to have changed drastically in this movie, though he retained his sense of humor and sarcasm from the first movie.
The practical effect of the Pachycephalosaurus was sculpted and painted by Scott Stoddard and was mechanized by Jeff Edwards and Richard Haugen. there were three versions that were created and employed for use in the movie, these three variants were a full size hydraulic puppet, an insert head, an animatronic of the Pachy in a ramming stance when it headbutts one of the vehicles of the hunters, also to know is that the Pachycephalosaurus was the only dinosaur in the round up scene that was not purely portrayed with CGI.
(at around 20 mins) Eddie's (Richard Schiff's) Lindstradt air rifle is completely fictional, but has a similar layout to a Dan-Inject IM with a Anschutz 1913 Super Match target rifle stock and overall design, and fitted with a Bushnell HOLOsight 400, adding that the Fluger subsonic delivery darts are filled with the venom of the Conus purpurascens (South Sea Cone Shell) actually means (the purple cone), the most powerful neurotoxin in the world. He adds the rather strange claim that it kills within one two-thousandth of a second, faster than nerve conduction velocity, so the target dies before it even feels the impact of the dart. While in reality, the lethal effect of some conotoxins is nearly instantaneous, the toxin would actually have to travel through the animal's body to the nervous system after being injected before it did anything, which would be distinctly slower than claimed.
The movie and novel have these plot elements in common: InGen used a second island, Isla Sorna, to clone and breed dinosaurs. A team of scientists, the Gatherers, travel to the island to study the dinosaurs. Another team, the Hunters, wants to exploit the dinosaurs. The Gatherers have a trailer. Members of the Gatherers include Dr. Ian Malcolm, Eddie Carr, and Sarah Harding. A girl named Kelly travels with the Gatherers as a stowaway. The Gatherers try to treat the broken leg of the baby T. Rex. The adult T. Rexes attack the trailer and push it over a cliff. Raptors attack the humans. Eddie Carr is killed by a dinosaur. The Gatherers try to call for help in the worker village. These plot elements were taken from the first novel: Bowman family visits a beach, and their young daughter is attacked by a (Pro)Compsognathus. Humans try to hide from a T. Rex behind a waterfall. A character breaks his leg and gets attacked by a group of (Pro)Compsognathus.
In addition to appearing together in this movie and its predecessor, Joseph Mazzello and Sir Richard Attenborough worked together as actor and director on Shadowlands (1993). Attenborough subsequently directed Pete Postlethwaite in Closing the Ring (2007).
(at around 46 mins) As in Jurassic Park (1993), this movie also features an SUV falling out of a tree. During the raid on the InGen base camp, a flaming SUV is tossed up into the air and crashes down in the tree in which Roland and Ajay are sheltering while hunting the T-Rex. It causes him and Ajay to jump out of the tree before crashing down to the ground, where it also lands on its roof.
(at around 1h 50 mins) When the Buck stops at a house to drink from the pool, a dog, tied to his dog house on a lead chain, sees the dinosaur and starts barking. The dog gets excited and moves toward the edge of the pool, dragging his dog house behind him. Later, you see the dog house hanging out of T-Rex's mouth, however, the dog is not seen. This scene was shot in cuts. The dog house was made out of light weight balsa wood with an aluminum bottom. The dog only had to drag the dog house a couple of feet. The trainer attached the dog to the chain and cued him with verbal and hand signals.
One of the movie-built "props" of the trailers was up for auction in Los Angeles on eBay. Unfortunately, the trailers were in very poor condition, however, photos taken for the sale provided far more information about the trailers.
(at around 1h 50 mins) One shot from the movie appears in the original entrance video of the World Wrestling Entertainment faction Degeneration-X. It's a shot of people running for their lives down the street to escape the rampaging dinosaur. The shot, from which seventeen frames are used, occurs at 1:52:57 in the movie, immediately after the bus drives through the video store. The footage was used by World Wrestling Entertainment in December 1997, but may have been used earlier than that.
Originally, the baby T. Rex was suppose to be brown, as seen on one of his marquettes in the behind-the-scenes featurette, meaning that he might have originally been planned to be female instead of male.
The tranquilizer gun Roland uses to tranqulize the male Tyrannosaurus is a modified LAR Grizzly Big Boar.
Roland seems to not know a lot about dinosaurs as he's unable to correctly pronounce Parasaurolophus and Pachycephalosaurus.
The gun Dieter Stark carries around is a Heckler & Koch HK91A2 with a surefire 660 entry light and with a telescopic sight, HK91 is also a semi auto civilian version of the Gewehr 3.
Sarah dismisses every single one of Ian's warnings, as well as several of her own throughout the movie, even after people have actually started dying, Ian gets rightly angry when she didn't bother to mask her or Nick's trail when they bring the infant T-rex to the trailer to mend its broken leg.
(at around 1h 50 mins) When the bus crashes into the Blockbuster Video, although the posters are for fake movies (King Lear, Jack and the Behnstalks, Tsunami Sunrise), the cases on the shelves are for real movies. These include Lethal Weapon 3 (1992), Wayne's World (1992), Scarface (1983), Field of Dreams (1989), and The Land Before Time II: The Great Valley Adventure (1994).
(at around 41 mins) Roland says to Ajay, that the Rex nest is upwind and so are they, which in hunting means that the wind is blowing from you to your target. An animal will pick up on even the slightest human scent with ease, so they would do everything possible to avoid being upwind of the Buck T-rex.
(at around 41 mins) Ajay says to Roland at the Rex nest "If he wants to make his blind here and wait for the Buck T-rex to return..."; a hunting blind, hide or machan is a cover device for hunters or gamekeepers, designed to reduce the chance of detection. There are different types of blinds for different situations, such as deer blinds and duck blinds. Some are exceedingly simple, while others are complex.
(at around 1h 9 mins) At one point, Roland Tembo (Pete Postlethwaite) says "Let's get this moveable feast underway." This is a literary reference. "A Moveable Feast" is the title of Ernest Hemingway's book of memoirs about his days in Paris in the 1920s with other American expatriots and literati.
Interestingly, in the script, the identity of Pachycephalosaur captured by the hunters was more vague as Dr. Burke initially identifies it as Pachycephalosaurus, but later afterwards identifies the animal as either once again being Pachycephalosaurus or Prenocephale.
Nick claims that he joined Greenpeace simply for the beautiful women who work there, and he also relishes the amount of money that can be made by selling authentic dinosaur pictures. However, he does express genuine concern for wild animals, as he removed the baby T. Rex from its entrapment and brought it to their trailer to mend its broken leg, even though he knows that it's a bad idea.
(at around 1h 30 mins) When Malcolm distracts the velociraptor away from Sarah and Kelly in the worker village is similar to Jurassic Park (1993) when Malcolm distracts Rexy/Roberta so Grant can save the kids.
The Mercedes M-Class Convertible is currently displayed at Universal Studios Orlando, and the other was last seen at AMI 2009.
Ian, upon learning that Sarah is already on Isla Sorna, is perfectly willing to jeopardize the lives of two people (whom he was about to stop from even going on the expedition) in order to ensure her safety, this is immediately after Ian tells Hammond to stop selfishly risking the lives of others for his own ends, upon retrieving Sarah on the island however, he spends the rest of his time trying to get them off of the island, and he does at least make token efforts to convince Eddie and Nick that staying any longer is not a good idea.
Paul Mejias sculpted and painted a 1/7th scale model from one of Mark 'Crash' McCreery's designs that stood 17 inches tall. Unlike the concept art, this painted maquette was a bright yellow. The head was also not completely red, with the crest being black and the only red found on its body being only on the back of its neck. Ultimately, the final sequence would feature the color of Parasaurolophus as having more of an earth tone and less red on the neck. A further two maquettes were made to reflect the change to earth tones with one having less red on the back of the neck than the other, the one with less red on the neck being nearly identical to the color scheme seen in the finished film. Another fully poseable maquette was created to serve as a reference for modeling the full sized carcass.
(at around 44 mins) Ludlow cites SeaWorld's success as one of the reasons to display dinosaurs in San Diego. Flash forward to a decade worth of sea mammal abuse controversies, up to being forced to discontinue the captivity of orcas altogether, and citing the park to justify anything now sounds downright asinine.
The dependence of young Tyrannosauruses on their parents is very apparent with this baby dinosaur. When it is injured and taken away from its parents, it barely ever stops howling for them, indicating that it is not yet capable of surviving on its own, and requires its parents to come to its rescue.
(at around 10 mins) At the beginning of the movie, when Ian (Jeff Goldblum) comes to see John Hammond (Sir Richard Attenborough), there is a picture on his desk of Lex (Ariana Richards) and Tim (Joseph Mazzello) from Jurassic Park (1993).
Despite concept art and one of the maquettes of the adult Stegosaurus depicting it with its tail dragging like older restorations, the Stegosauruses in this movie and Jurassic Park III (2001) lacked this trait, although the Stegosaurus in Jurassic World (2015) featured it briefly dragging its tail along with a Triceratops that did the same, like with the Pachycephalosaurus which appears in the movie also with Stegosaurus, the Stegosaurus went through many changes in terms of its coloration. Mark Maitre was responsible for creating a total of six of these conceptual skin colorations.
A hadrosaur skull can be seen amongst the pile of bones in the Tyrannosaurus Rex nest. Jurassic Park Legacy members long concluded that it belonged to the genus Anatotitan, which is now classified as Edmontosaurus annectens. It is unknown if Edmontosaurus was on Isla Sorna or was even re-created by InGen before Jurassic World (2015) in the movie canon.
(at around 38 mins) During the game trail scene, Roland refers to a parasaurolophus as "Elvis", due to the crest atop its head, which vaguely resembles Elvis Presley's famous pompadour hairdo.
Some fans believe that Tembo's failure to tell Sarah to get rid of the jacket covered in the baby T. rex blood was deliberate on his part; he was in fact counting on the blood to lure the T. rex parents to the camp so he can get the chance to kill the Buck Rex. He just didn't count on Nick sabotaging his bullets.
(at around 35 mins) Roland Tembo (whose last name means elephant in Kiswahili) tells Peter Ludlow that he'd, "been on too many safaris with rich dentists." Coincidentally, the tourist and hunter who killed the beloved lion Cecil in South Africa in July 2015 was a rich dentist.
Searcy double barrel rifles are often referred to simply as a "double", referencing the two barrels per single rifle. Double rifles are the favored rifle for African professional hunters, as the two barrels allow for a quick follow-up shot on animals without having to reload. The weapon seen in this film was manufactured by B. Searcy & Co. of Boron, California. Two rifles were made for the production of this movie. Director Steven Spielberg owns one of them. The location of the other is unknown. Both rifles are real and fully functional. As with all double rifles, the intense amount of time and labor to make them dictates a price tag of several tens-of-thousands of dollars. A plastic model was made as well for stand-ins when the real rifle, which is heavy, was not necessary.
(at around 50 mins) When Sarah is tending to the infant Tyrannosaurus' broken leg, Nick refers to her as "Dr. Quinn", referencing Dr. Quinn, Medicine Woman (1993), which also came out the same year as Jurassic Park (1993).
According to the video game that accompanied the movie, the Captain of the S.S. Venture was D. Thompson.
This movie features two actors from the Death Wish film franchise. Jeff Goldblum played Freak #1 (leader of the thugs who mauled Paul Kersey's wife and gang-raped his daughter) in Death Wish (1974) and Thomas F. Duffy played Nirvana in Death Wish II (1982). Both were the causes of Paul Kersey's (Charles Bronson's) vigilante rampage.
(at around 1h 50 mins) When the Buck Trex singles out and eats the unlucky bastard, is similar to the first film when Rexy/Roberta singled out the gallimimus during the stampede.
The film popularized Compsognathus. Post-TLW games, like Tomb Raider III: Adventures of Lara Croft (1998), also feature Compsognathus as they are portrayed in the film.
In the first film, Steven Spielberg payed homage to Stanley Kubrick's The Shining (1980) in the scene where the velociraptors stalk Tim and Lex in the kitchen. In this film, he casts Arliss Howard, who appeared in Full Metal Jacket (1987). His cast mate Vincent D'Onofrio appeared in Jurassic World (2015).
(at around 1h 30 mins) When Malcolm runs into the car to escape from the Velociraptor, from the raptor's point of view you can see Malcolm locking the car door with his right foot, a reference to the first film in which the Velociraptors figured out how to open doors.
(at around 1h 35 mins) In slow-motion when the Velociraptors are fighting at the worker village, motion blurs from the animation and lighting composition fools audiences into thinking that the male raptor has the upper hand as it pins down the female, but closer inspection shows after the raptors tumble again it's the female that comes out as the victor. Showing that in a pack the female has the most strength.
In the first film the velociraptors are shown to have outsmarted humans in the climax, in contrast to this in this film, the humans either dodge, avoid or outsmart the raptors resulting in them fighting.
Mobility was essential for the scene in which the T-rexes attack the trailer. Working on a stage set at Universal, the Winston crew gleefully rammed the T-rex rigs into the vehicle over and over again. "I think out of everything on this movie," said Shane Mahan, "we had the most fun smashing up the RV with the two T-rexes. At first, we were hesitant, thinking that we had to be careful with the rigs. But it got to the point where we were just, 'Ah, to hell with it,' and we just demolished that trailer with the T-rex rigs. That scene wasn't faked. Those T-rexes were really slamming into that thing, breaking glass and shaking it. I think the scene really works because we went for it like that. You can tell that something truly violent is happening."
Shane Mahan and a team of Stan WInston Studio puppeteers conducted extensive rehearsals with the compy rod puppet to prepare for the opening beach scene in The Lost World: Jurassic Park, which would be shot in Kaui. "I actually built a little sandbox here at the studio," said Mahan, "and we used that to rehearse the Compy rod puppet hopping in, biting a piece of bread, swallowing it, and looking around. We got it down cold."
Although the Compys that are first seen running in the forest and jumping onto Peter Stormare were computer animated, the actual attack on the hunter was accomplished almost entirely with practical puppets. Stan Winston Studio built a dozen Compy puppets, of four different types, to create the range of behaviors required in the scene. "Very often, producers will say, 'Just make a general puppet,'" said Shane Mahan long-time SWS Supervisor and co-founder of Legacy Effects. "It costs them less to have us build one puppet that can do a handful of general things; but making a general puppet is never as good as making different puppets that can perform specific functions really well." One type of Compy puppet was attached to the actor by velcro, and rigged with a fishing line that ran to a controller. By tugging on that controller, the puppeteer created a pecking motion. Another type of Compy puppet featured high-powered magnets on its feet to adhere the puppet to the actor's clothes, which had attracting magnets sewn into them, allowing for shots of the character grabbing Compys and pulling them off. The mechanical crew inserted springs into the magnet Compy to give it a bit of neck movement. The "Hero" Compys were mechanized with servos to create full head movement, with pneumatic eye blinks and tail movement. The featured hero Compy had all the same functions, plus fully articulated arms that could grab at the actor while attacking. Stan Winston himself was impressed with the final effect in the movie. "Some of these puppets were very simple," Winston said, "strings and springs, basically. But they worked beautifully. Between those simple puppets and the more mechanized ones, we were able to create this violent cacophony of Compy performance.
Arliss Howard plays the nephew of Sir Richard Attenborough and therefore a first cousin once removed to Joseph Mazzello. Attenborough directed Mazzello in Shadowlands (1993). In that movie, Howard's wife, Debra Winger, played Mazzello's mother.
(at around 1 min) The Bowman family (Paul, Diedre) drink Perrier-Jouët Champagne, which is produced based in the Épernay region of Champagne. The house was founded in 1811 by Pierre-Nicolas-Marie Perrier-Jouët, and produces both vintage and non-vintage cuvee, approximately three million bottles annually, with its prestige label named Belle Epoque. Today the house is under the Pernod Ricard umbrella of brands. One of the three bottles of the world's oldest champagne, a Perrier-Jouët (vintage 1825) was opened and tasted in 2009.
It is known that Roland is an expert hunter, and he may have a personal moral code.
(at around 1h 26 mins) The Velociraptors ambushing and killing the unsuspecting hunters wandering in the long grass brings in mind of Pokémon to modern audiences, especially with the line "Don't go into the long grass!"
Other characters compare Dr. Harding to Dian Fossey and Dr. Quinn. In Gorillas in the Mist (1988), Fossey was played by Sigourney Weaver, who appeared with Julianne Moore in A Map of the World (1999), and with Jeff Goldblum in Annie Hall (1977). She was also considered for the role of Ellie Sattler in the original Jurassic Park (1993). Dr. Quinn was played by Jane Seymour, who was once the daughter-in-law of Richard Attenborough. The early episodes also featured Diane Ladd, mother of Jurassic Park (1993) cast member Laura Dern.
Ian Abercrombie, who plays Hammond's butler, also appeared on Twin Peaks (1990). Laura Dern went on the appear on the 2017 revival. Both series also featured a guest appearance by David Duchovny, whose ex-wife, Téa Leoni, appeared in Jurassic Park III (2001), and who played Jeff Goldblum on an episode of Saturday Night Live (1975).
Ian Malcolm (Jeff Goldblum), John Hammond (Richard Attenborough), Lex (Ariana Richards), and Tim (Joseph Mazzello) are the only characters to return in this movie from Jurassic Park (1993).
(at around 35 mins) The Mamenchisaurus only appears during the scene where InGen is rounding up as many dinosaurs they can find. It hasn't made a single on-screen appearance since then.
This is not the first live-action appearance of Stegosaurus and Compsognathus in the franchise. Both species made an Early-Bird Cameo in Jurassic Park: The Ride, which opened at Universal Studios Hollywood a full year before this film in 1996. Additionally, Compys were supposed to appear in the first film and scenes featuring Compy models were even filmed for the scene where Rexy escapes her paddock. On top of that, both also featured in the original novels. (Technically it's Procompsognathus in the novels, but they fill the same roles and are virtually identical -- one of Burke's lines even acknowledges this by flubbing the compy's name as Compsognathus triassicus, combining the genus of one with the species of the other.)
In terms of aesthetics, at least, the Roland Tembo character takes a lot of cues from Dr. Snare, a non-canon character from the Jurassic Park Series 2 toy line.
In the novel, a T. rex chases Lex and Tim behind a waterfall. (For movie viewers, this is similar to a scene in this sequel).
Roland thrives on being in control of any situation, and really feels right at home in the wilderness.
Steven Spielberg: [signs] (at around 1h 50 mins) When the T. Rex bites the traffic signal in San Diego, a street sign on the right edge of the screen reads in part "NO DINOSAURS".
Steven Spielberg: [signs] (at around 1h 45 mins) Using a sign with directions or instructions as a joke. In this case, the T-Rex crosses the pier at the San Diego port bearing a sign that reads, "No animals or vegetables beyond this point."
