Stanley Kubrick worked on the project for two decades before his death, but along the way, he decided to ask Steven Spielberg to direct, saying it was "closer to his sensibilities". The two collaborated for several years, resulting in Kubrick giving Spielberg a complete story treatment and lots of conceptual art for the movie prior to his death, which Spielberg used to write his own scenario. Contrary to popular belief, Spielberg claims that he introduced many of the darker elements into the story, while Kubrick's main contribution consisted mostly of its "sweeter" parts. In a 2002 interview with movie critic Joe Leydon, Spielberg indicated that the middle part of the movie, including the Flesh Fair, was his idea, whereas the first forty minutes, the teddy bear, and the last twenty minutes were taken straight from Kubrick's story. Ian Watson, who wrote Kubrick's original treatment, confirmed that even the much-criticized ending, assumed by many to be a typical Spielberg addition, was "exactly what (he) wrote for Stanley, and exactly what he wanted, filmed faithfully by Spielberg."

In order to further his non-human appearance, each day before filming, any of Haley Joel Osment's exposed skin (face, arms, hands, et cetera) was shaved to give him a more plastic look.

For the last seven minutes of this movie, composer John Williams wrote a piano concerto, and it went over the length of the movie. Director Steven Spielberg stopped the projector and told Williams to just let the music continue. Spielberg, along with editor Michael Kahn, then re-edited the last seven minutes of movie into Williams' piano concerto. Spielberg did a similar thing nineteen years before on E.T. the Extra-Terrestrial (1982), where he and Carol Littleton edited the last fifteen minutes into Williams' music.

The list of words that Monica Swinton (Frances O'Connor) says to David (Haley Joel Osment) to make him capable of love was the original list, written by Stanley Kubrick.

This movie also pioneered the virtual studio, a technique which allowed director Steven Spielberg to walk through a virtual version of Rouge City with his camera and select shots. This technique was used on The Lord of the Rings trilogy.

Real-life amputees played some of the robots with missing limbs.

It was Stanley Kubrick's idea to include industrial metal band "Ministry" to the movie. He was a big fan of them, and called lead singer Al Jourgensen asking him if he would like to be in the movie, Al, assuming it was just a prank, hung up on him.

Haley Joel Osment suggested to Steven Spielberg that his character (David) should not blink. Spielberg agreed and went further to suggest that none of the androids should blink. In fact, several of them do (see goofs).

The World Trade Center is seen in the New York City scenes of this movie, set many years into the future after 2001. Less than three months after this movie's release, they were destroyed in the September 11 terrorist attacks. Though risking controversy and criticism, Steven Spielberg left the twin towers in the DVD release.

The movie was originally to be titled "A.I.", but after a survey it was revealed that too many people thought it was A1. The title was changed to A.I. Artificial Intelligence to prevent people from thinking it was about steak sauce.

In order to keep the film's PG-13 rating, a building resembling a penis was digitally removed from the "Rouge City" set.

Steven Spielberg used the water-filled set from The Perfect Storm (2000) for the flooded world of the future in this movie.

Robin Williams recorded his dialogue for this movie with Stanley Kubrick directing the recording session, he did it a long time before Steven Spielberg was attached to direct. In Bicentennial Man (1999), Williams plays an android who wants to become human.

This movie takes place in 2142 and 4142.

The elaborate series of promotional websites included information about the characters' lives after their last appearances in the movie. For instance, one website revealed that Martin Swinton grew up to be an architect who, after being traumatized by David's disappearance, spent his career building sentient A.I. houses.

David's head is very often shown with a "halo" of circular light; the kitchen light, the dinner table lights, the lights in his bed, the shot from the rear-view mirror, the full moon, et cetera.

The SuperRobots in the final act look like the aliens from Close Encounters of the Third Kind (1977); apparently, Steven Spielberg was using scenes dropped from that movie at the time due to special effects constraints and never filmed, until they appeared in this movie. The resemblance was so great, that early reviews criticized the movie for the sudden and unwarranted appearance of aliens at the end (a belief that still persists with some). The studio went as far as issuing statements at several foreign press screenings that the entities at the end are very advanced robots, not aliens.

While this movie was based on the Brian Aldiss short story "Supertoys Last All Summer Long", that short story has less influence on the movie than the famous poem by William Butler Yeats, "The Stolen Child." The text of the poem appears in the movie in two places, and certain stanzas take on literal meaning as well (for example, "Till the moon has taken flight"). There are also many surprising similarities to the Philip K. Dick short story "Second Variety".

Steven Spielberg's first writing credit since Poltergeist (1982).

Although Jack Angel recorded all of his voice work for Teddy while separate from the rest of the production, he was asked to be on-set every day, to re-record lines immediately when necessary.

Shot in sixty-seven days.

One of the buildings in Manhattan is actually an Apple Macintosh (Harman-Kardon) subwoofer.

After seeing Chris Cunningham's work on Judge Dredd (1995), Stanley Kubrick head-hunted Chris Cunningham to design and supervise animatronic tests of the central robot child character in his version of this movie. Cunningham worked for over a year on this movie, before leaving to pursue a career as a director.

The band playing at the flesh fair, Ministry, was chosen by Stanley Kubrick, after overhearing a crew member playing a Ministry album one day on the set of Eyes Wide Shut (1999). Kubrick was also said to have liked the band because they used audio samples from his film Full Metal Jacket (1987) in their 1989 song "Thieves".

The character name "Professor Hobby" is an obscure reference to Stanley Kubrick, who produced his movies in the U.K. under the name "Hobby Films", which never appeared on-screen in any of his movies.

As a promotional tool, the creators developed an elaborate internet game of discovery and problem solving, through hidden messages and puzzles in internet sites, telephone answering messages, e-mail accounts, and clues in the movie's trailers. The game, set in the world of this movie, involved websites registered in several countries around the world, as well as telephone numbers from across the U.S., and a group of followers called "The Cloudmakers" followed the puzzle, sharing information.

Includes many of the trademarks of Stanley Kubrick. Among these are the narration at the beginning; portrayal of dehumanization and the dark side of human nature; the tracking shots down the length of tall, parallel walls, and "The Glare", with David's head tilted and eyes looking upwards; the scene in the bathroom; the three-way conflict between David, Monica and Martin; an obsessed hero; imaginary worlds; a journey towards freedom and knowledge; the use of classical music in Richard Strauss' "Der Rosenkavalier". Perhaps the most direct homage to Kubrick's work is when David is stuffing spinach into his mouth in an attempt to compete with Martin, and Henry yells "stop Dave, please stop!"; the dialogue is taken almost literally from the final scene between HAL and David Bowman in Kubrick's 2001: A Space Odyssey (1968).

When David (Haley Joel Osment) and Gigolo Joe (Jude Law) first arrive at Rouge City, and they drive through an arch shaped like a giant mouth, the movie used a piece of music selected by Stanley Kubrick when he was still considering directing. John Williams thought the music fit perfectly with the way the scene was shot by Steven Spielberg.

When David and Gigolo Joe first arrive in Rouge City, they pass a milk bar. This is a reference to Stanley Kubrick's A Clockwork Orange (1971), which opened at the Korova milk bar.

When work began on the movie in 1993, Joseph Mazzello was cast as David.

In some trailers for the movie, the words, "THIS IS NOT A GAME" were printed in glowing red letters at the bottom of the screen.

Director Steven Spielberg cast Kathryn Morris in the role of rock star Teenage Honey after seeing her in The Contender (2000). To prepare for the role, Morris took guitar lessons and singing lessons. Spielberg then cast Morris in Minority Report (2002). During the shooting of that movie, Spielberg was simultaneously editing this movie and Morris' scenes ended up on the cutting-room floor (though she is still credited). Morris told nymag.com "When I saw Steven on the set, he was like, 'Kath, I am so sorry. Do you hate me?' I said, 'You know, somehow me sitting here with you on the set of your film, working opposite Tom Cruise, makes it kind of okay.'"

John Williams used Richard Strauss' "Der Rosenkavalier" waltz in the underscore during the approach to Rouge City. This was a done to honor Stanley Kubrick, who left few notes regarding the music, except to tell Steven Spielberg that this Strauss waltz should appear in the movie. Williams refers to his score, which contains several musical allusions to Kubrick's movies, in addition to the waltz, as his "homage a Kubrick".

Stan Winston claimed this was the most ambitious movie on which he worked in his lifetime.

The hotel, into which Gigolo Joe walks, when we are first introduced to the character, has the Hebrew words "Ahava Kshera" in neon (Kosher Love).

Much of the promotional material sent to movie theaters (posters, stand-ups, et cetera) misspelled director Steven Spielberg's first name as "Stephen".

William Hurt played a remarkably similar "father of intelligent androids" scientist in BBC's science fiction drama Humans (2015).

Kubrick and Spielberg originally approached studio executives with the script for A.I. by pitching it as "Blade Runner meets Field of Dreams."

When David (Haley Joel Osment) and Gigolo Joe (Jude Law) are journeying through the woods, they mention Haddonfield, New Jersey, where Steven Spielberg lived for several years as a child.

Jerry Seinfeld was originally considered to voice and play the Comedian robot.

The DreamWorks SKG logo is featured several times, but most prominently in Martin's bed.

At the preview showings of the movie, special posters were placed in the theaters with a list of credits for the "Puppetmasters": Jordan Weisman, Elan Lee, Scot Bayless, Sean Stewart, Dan Carver, Pete Fenlon, Todd Lubsen, Paolo Malabuyo, Mark Selander, Mike Pondsmith, Lynn Knight, David Wells, Shawn Ferminger and Christine Hill. No regular movie posters were displayed that night. The "Puppetmasters" were a team from Microsoft, with Steven Spielberg's blessing, and quite outside the studio's wishes, that ran the Internet game. No movie credits were listed. Many of the players' on-line game names were in vertical lists in an outline of the regular A.I. "Initials" movie poster.

Sound effects from "The Jetsons" 1960's TV series can be heard in the "Dr. Know" (Robin Williams) sequence when David and Gigolo Joe are asking questions.

The first part of Steven Spielberg's unofficial "running man" trilogy, continuing with Minority Report (2002) and concluding with Catch Me If You Can (2002).

The first movie to use computer animated Pre-Vis.

The light fixture in Professor Hobby's (William Hurt's) lab was also used in the war room set of Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964).

The screenplay "borrows" liberally from Osamu Tezuka's 1952 manga Tetsuwan Atomu (known as Astro Boy in the English speaking world), in which a scientist creates an emotion-capable boy robot to replace his dead son, but becomes frustrated when he realizes the robot will never grow up or become human. He sells Astro Boy to the Robot Circus, where he's forced to do battle with other robots in gladiator-style combat.

Of all the robots designed, the most difficult to conceptualize was Teddy, the 'supertoy' that would be a featured player in the film. "Designing Teddy was a huge job," said Winston, who hired his largest crew ever to complete the robot construction project. At the height of production, Stan Winston Studio boasted 140 artists and technicians. Building Teddy, a more sophisticated and complex animatronic than any of the dinosaurs in Jurassic Park, required that increased manpower, plus the ingenuity and talent of many artists and technicians. "We'd given our Velociraptor thirty-four points of motion," explained Winston, "and our T-rex, forty points of motion. But Teddy had fifty points of motion, all in a little character that was less than three feet tall. He had to act, he had to talk, and he had to deliver a varied and convincing performance. We had to create the ultimate robotic teddy bear -- and that was the biggest, most difficult job we'd ever taken on."

Julianne Moore and Gwyneth Paltrow were considered for the role of Monica.

The imprinting words sequence: Cirrus, Socrates, Particle, Decibel, Hurricane, Dolphin, Tulip. (Monica, David, Monica)

The Insecurity Robot's face was based on Stan Winston's.

When Gigolo Joe and David fly through the flooded ruins of New York City in the Amphiblicopter, the Statue of Liberty can be briefly seen submerged in the ocean up to the bottom of her torch. In Russell Ash's 1996 book "Incredible Comparisons", it is described that if all the world's ice melted, this is exactly what would happen to the statue.

Before this movie's release, Steven Spielberg assigned video game developers at Microsoft the task of developing a series of games based on this movie for the XBox game system.

(At around ten minutes) When first introduced to David, before David is actually seen in the bright lights, his image is undoubtedly similar to that of the bodies of the evolved A.I. robots at the end of the movie.

Spielberg passed on Harry Potter and The Sorcerer's Stone and Jurassic Park 3 to direct this film.

DIRECTOR TRADEMARK (Steven Spielberg): (moon): The large moon visible in many scenes, is in the logo for the Flesh Fair, and appears as the design on Lord Johnson-Johnson's (Brendan Gleeson's) "balloon" aircraft.

This movie is included on Roger Ebert's "Great Movies" list.

Gigolo Joe's medallion has "Shangri La" written on it when he starts playing music in the hotel room.

One of several movies to unite Haley Joel Osment and Eugene Osment. The others being Last Stand at Saber River (1997), The Ransom of Red Chief (1998), Bogus (1996), I'll Remember April (2000), Pay It Forward (2000), Edges of the Lord (2001), Secondhand Lions (2003), and Home of the Giants (2007). Eugene is Haley's father.

Teddy (Jack Angel) has a voice similar to the monotone computer Hal 9000 (who said "Dave" instead of "David" as Teddy does) from Stanley Kubrick's 2001: A Spacey Odyssey (1968).

Included among the "1001 Movies You Must See Before You Die", edited by Steven Schneider.

The cast includes four Oscar winners: Robin Williams, Sir Ben Kingsley, Meryl Streep, and William Hurt, and two Oscar nominees: Haley Joel Osment and Jude Law.

Some sources claim that in the scene at the Flesh Fair, when Lord Johnson-Johnson (Brendan Gleeson) says to the crowd, "Let he who is without sim cast the first stone", the man who stands and hits him with the first bean bag is Rutger Hauer, who played the replicant Roy Batty in Ridley Scott's Blade Runner (1982), which is also about extremely humanized androids. However, that man is not Rutger Hauer.

When he was approached by Steven Spielberg, Stan Winston had more experience building robots than any other creature effects artist in the world -- but the robots of AI would be unlike anything Winston, or anybody else, had ever created. "It was important to Steven that the robots in AI have absolutely nothing to do with the Terminator or any of the robots we'd done previously," Winston remarked.

When David meets Gigolo Joe, they soon thereafter witness a garbage truck dumping mecha parts in the forest. The parts were actually Stan Winston Studio reject designs that prop master Jerry Moss mass-produced from Winston's molds.

For all his creativity, Stanley Kubrick was more interested in the "appearance" of the future than what the future would actually be like. In 2001: A Space Odyssey (1968), the only women are servers and secretaries. In this movie, he imagines three wheeled pod cars (still driven by humans, which probably won't be the case in the future shown in the movie), but people in this future are still using land line phones.

It marks as the first collaboration between Director Steven Spielberg and Meryl Streep, even though she only provided her voice in the movie. Their first on-screen movie together is The Post (2017).

DIRECTOR TRADEMARK (Steven Spielberg): (music): John Williams' score.

Damaged mecha outcasts rummage through the pile, looking for replacement parts. The studio designed twelve key mecha characters for the scene -- including a security guard mecha that was built from a lifecast of Stan Winston -- each of which was realized as either a mechanical puppet or an appliance makeup worn by a performer.

According to FX Mechanic Eric Fiedler, recreating Stan Winston as Mecha involved multiple approaches, "The Insecurity Guard was primarily a kinetic rod puppet where all the joints articulated like normal human joints. It had a cable-operated neck. The head was silicone. The armature for the body was aluminum rods, bearings, torsion springs, all nicely machined."

Steven Spielberg and Robin Williams' second collaboration after Hook (1991).

Steven Spielberg and Eugene Osment worked on Minority Report (2002).

Cast member Robin Williams died on August 11, 2014. He was followed in death the next day by Lauren Bacall, mother of cast member Sam Robards.

When we first see David's silhouette, the light distorts it to resemble the body shape of one of the future mechas.

"[The Mechas of AI: Artificial Intelligence] were unlike anything audiences had seen before," said Winston, "and we were able to do it by using all of the available technologies." From live-action puppetry to traditional makeups and Practical/CGI hybrid approaches, the Stan Winston Studio robot makers pushed themselves to a brand new level of innovation by bringing every magic trick to the table, all to help Steven Spielberg make his modern day Pinocchio a reality.

Meryl Streep and Jude Law appeared in A Series of Unfortunate Events (2004).

Brendan Gleeson and Jude Law appeared in Cold Mountain (2003).

Jude Law, William Hurt, and Clark Gregg have all appeared in the Marvel Cinematic Universe. William Hurt appeared in The Incredible Hulk (2008) as Gen. Ross. Clark Gregg appeared in various titles, most notably Agents of S.H.I.E.L.D. (2013) as Agent Coulson. Jude Law appeared as Yon-Rogg in Captain Marvel (2019).

Jude Law and Brendan Gleeson have both been part of J. K. Rowling's Wizarding World. Brendan Gleeson appeared in Harry Potter and the Goblet of Fire (2005) as Alastor Moody. Jude Law played Albus Dumbledore in Fantastic Beasts: the Crimes of Grindlewald (2018).

Jude Law and Sir Ben Kingsley played Dr. John Watson in Sherlock Holmes movies: Sherlock Holmes (2009) and Without a Clue (1988), respectively. Stanley Kubrick's movie Barry Lyndon (1975) also featured two Watsons: André Morell from The Hound of the Baskervilles (1959), and Michael Hordern from Young Sherlock Holmes (1985), which Steven Spielberg produced.

Meryl Streep and William Hurt appeared in One True Thing (1998).

Meryl Streep and Brendan Gleeson appeared in Suffragette (2015).

When cleaning the spinach our of his body, a technician tells Davis that spinach is for humans and Popeye. Robin Williams played Popeye, and Olive Oyl was played by Shelley Duvall, who also appeared in The Shining.

William Hurt has appeared in several films for director Lawrence Kasdan. Kasdan wrote Indiana Jones and the Raiders of the Lost Ark (1981) for Steven Spielberg, and it was during pre-production for that film; when touring Elstree Studios; that Spielberg met Stanley Kubrick, who was filming The Shining (1980) at the time.

Adaptation from L. Frank Baum's 'Wizard Of Oz'.

Meryl Streep worked with Sam Robards's father, Jason Robards, in one of her earliest films, Julia. Her next film with Spielberg was The Post, which starred Tom Hanks in a role previously played by Robards in All the President's Men.

Joseph Mazzello, who was considered for the role of David, previously worked with Spielberg on Jurassic Park. The scene where he locks a velociraptor in the kitchen freezer was a reference to Kubrick's film The Shining. Brendan Gleeson appeared in Harry Potter and the Goblet of Fire, the climax of which took place in a hedge maze, like The Shining.

Rena Owen also appeared in Star Wars: Episode II - Attack of the Clones, with Ewan McGregor. McGregor was Jude Law's roommate at drama school, and has his own connection to Stanley Kubrick: he appeared in Doctor Sleep, the sequel to The Shining.

Stanley Kubrick's film The Shining involved a writer trapped by a blizzard in Colorado, and was based on a Stephen King novel. King wrote another novel involving those same elements: Misery. The cast of that film included James Caan; who appeared in Spielberg's film 1941; and Lauren Bacall; who was Sam Robards's mother.

Steven Spielberg: [rear-view mirror] Important image seen in rear-view mirror.

There are no shots of David blinking until the end, when he is perceived as a real boy.

Although implied by the movie, John Williams confirmed that David does indeed die in the last scene of the movie.

After Joe finds Samantha dead, he says that the number of seconds since the last time they met is 255,133, which is 2 days, 22 hours, 52 minutes and 13 seconds.

Steven Spielberg: [father] David and Henry are somewhat distant from each other and, while Monica performs the imprinting sequence with David, Henry never does. Professor Hobby made David in the image of his own dead son. He tells David he's as real a boy as he's ever made; in a way, he has to lose his son again.

At the beginning of the movie, Martin was frozen until he could be healed and reunited with his parents. At the end, David is frozen until he could be reunited with his mother.
