Trivia: In the entire film, there are only two "homegrown", real humans - Tank and Dozer. They both have names of machines.
Trivia: The Iron Giant has only 53 words of dialogue in the entire film.
Trivia: Immediately after General "Bloodbath" McGrath is killed by Loveless we see a little dog approaching the dead body and looking with curiosity at the device in his ear. This shot resembles the famous logo of the RCA VICTOR company .
Trivia: The scene near the end of the film where the bad guy kills all of the Galaxy Quest crew is very similar to a scene in the '70s British sci-fi TV show Blake's 7. In that scene, the crew are shot one by one in the same fashion as in this scene.
Trivia: The cyclops thumb in the bar, who says, 'Woo-hoo' is in every thumb movie.
Trivia: The termination code for Seth is "NCC170182461VIR" - whoever came up with that probably also likes "Star Trek" since the USS Enterprise's registration number reads 'NCC-1701'. That the following numbers add to 10 in pairs of two (8 2 and 4 6) while 'VIR' is the Latin word for 'man' (which 99% of the film's cast are) might simply be a coincidence - but then, perhaps not... (01:08:56)
Trivia: Ray Walston, who plays Nineenert, played the original Uncle Martin in the TV show "My Favorite Martian." In the movie he says his antennae are always giving him problems and everything is in black and white and that his gum had lost its flavor in '66. The original TV show was in black and white and its final season was in 1966.
Trivia: When the hand is killed and Mick complains about how there was "no explosions of hellfire," this is actually an inside joke. The original ending was completely different, and involved a giant portal, explosions, hellfire and tons of effects. However, this ending was dropped because the filmmakers felt it too scary compared to the rest of the movie. A new, more comedic ending was then shot. Mick complaining about the hand's simple death is a reference to the original, more intricate ending.
