Trivia: The main characters are taken from other sci-fi movies. The Missing Link is meant to be The Creature From The Black Lagoon (1954); B.O.B. is meant to be The Blob (1958); Ginormica is based on Attack Of The 50 Foot Woman (1958); Dr. Cockroach is copied from The Fly (1958); and Insectosaurus is based on Mosura (1961).
Trivia: At the climax of the movie when Russell Crowe confronts Senator Collins about his involvement with the death of the senate research aid, he goes outside to leave and is accosted by the assassin, Robert Bingham. Bingham is apparently going to kill Crowe when the police show up in force. Bingham raises his M-16 to shoot Crowe and the police shoot him. In the next scene Crowe is entering the news article in the newspaper's computer. The camera gives us a glimpse of the computer screen. If you pause it and read the story it says that the assassin, Bingham, is found by the police dead at his apartment from an apparent suicide instead of being shot down in a fusillade of police gunfire in front of Senator Collins' office.
Trivia: Reese's introduction isn't the only thing that stays the same about the character between movies. Here he uses his preferred weapon - a sawed-off shotgun. Marcus isn't keen on having a gun aimed at him though, so he snatches it out of Reese's hands, then teaches him a trick to keep that from happening - fashioning a safety strap. Reese puts that same trick to use after he steals a police shotgun in The Terminator. (00:49:55 - 01:49:58)
Trivia: In the scene where Ripcord and Duke are in the transport and Ripcord pats Heavy Duty on the back and gets his arm twisted as a result, Ripcord makes a crack about Heavy Duty having a "Kung Fu Grip".

Trivia: When the planes bombard the desert ruins, the explosion, which holds the Guinness record, took 8 months to be made, more than principal filming took!
