Trivia: The Iron Giant has only 53 words of dialogue in the entire film.
Trivia: For production designer Ken Adam's giant Pinewood volcano set, some 700 tons of steel were used, and some 250,000 square yards of canvas. It featured a working monorail and elevators and cost £1 million to produce.
Trivia: Hammond doesn't appear in the second book (though he does in the second movie). This is because, in the book series, Hammond was killed in the first book. He slipped, broke his ankle and was fatally attacked by compies.
Trivia: Kevin Spacey had to record the scene where Prot eats a whole banana (skin and all) 27 times.
Trivia: Steven Spielberg saw this film when he was a child and was fascinated by the Martians. He later based E.T. from E.T. the Extra-Terrestrial (1982) on them.
Trivia: Never in Oscar Wilde's story was Dorian Gray invincible, as is depicted in the film. Nor did looking upon his picture kill him. Dorian regularly stood in front of the painting, observing the degradation of his soul. He was only killed when he tried to destroy the picture.
Trivia: The Spierig bros. went to their butcher and bought rotten chicken and pig guts to enhance the effects.
Trivia: If you look closely with time-frame advance during the pigeon scene you will see a fish "flying" into a window instead of a pigeon. (00:08:35)
Trivia: In the end credits, an actor is credited as playing Young Ruafo. There are no scenes in the film which this character appears, this is a scene cut from the film, but they forgot to erase the credit. The explanation is that young Ruafo was filmed in the original Insurrection ending, before producers decided on a different (more action based) death for Ruafo and so had him burn on the exploding ship.
Trivia: Vinnie Jones claimed he was offered a cameo role in this film reprising his role as Juggernaut from X-Men: The Last Stand, but turned it down as he did not like the process of having his costume put on.
Trivia: The scene with Jill eating Wesker's sandwich and saying "It's Jill's sandwich now!" (although saying it quickly in such a way that you can't hear the "s" and it sounds more like "It's Jill sandwich now!") is a reference to an infamous moment in the original video game. In the game, Jill is almost crushed by a booby-trap, and the character Barry says she was "almost a Jill sandwich!" The poor dialogue and terrible delivery by the voice actor ended up making the moment a meme many years later.
Trivia: Jax says that Cole beat Eddy Tobias in a fight. This is a reference to the creators of Mortal Kombat, Ed Boon and John Tobias.
Trivia: When Roy McBride is reviewing a top-secret message regarding his father and the LIMA mission, the message filename is "6EQUJ5," which is a very obscure easter egg in the movie. The filename 6EQUJ5 refers to the real-life "WOW Signal," a deep space radio signal received by the Big Ear radio telescope at Ohio State University in 1977. The alpha-numeric designation "6EQUJ5" was a printed readout of the signal's duration and intensity. This signal lasted 72 seconds and was 20 times stronger than background radio noise, causing a surprised astronomer to circle the printed 6EQUJ5 readout in red ink and make the handwritten notation "WOW!" in the margin. While the signal was an anomalous one-time event that was never repeated, and there is still no proof that 6EQUJ5 was alien in origin, it has stimulated debate about extraterrestrial radio signals for decades. Ironically, the movie "Ad Astra" concludes that there are no alien radio signals and that we really are alone in the universe.
Trivia: When Dwayne Johnson signs to George to calm him down, he says "it's me." The sign he makes on those words is for "Rock," a reference to his stage name "The Rock." (00:15:25)
Trivia: Jennifer Connelly voices the "suit lady", the AI in Spider-Man's suit. In real life she's married to Paul Bettany, who voiced Jarvis, the AI in Iron Man's suit, and who later played Vision.
Trivia: When Billy is fighting evil Jimmy, he says "Shadow demon, you shall not pass." Look behind Billy. The actual Double Dragon arcade machine is behind him, which evil Jimmy then kicks. (01:17:40)
