Trivia
A very early reference to computer "firewalls" is mentioned in this film. See more...
Plot hole: At the end, the suggestion to unplug W.O.P.R. to prevent the missiles from being launched was actually the right suggestion. Given that W.O.P.R. was guessing the launch code by brute force, the actual order to launch the missiles wouldn't be given until the launch code was determined and therefore the silos would not interpret anything until they received not only the order to launch but with the right launch code.
Continuity: When Matthew Broderick plays "Galaga" in the arcade you can clearly see two more space ships (2 more lives) in the left down corner. When he is hit the game is over... Someone said that the game isn't over, when he dies he lets the kid take over his game because he has to run to class, but there are two scenes in the film where he's playing Galaga. The first scene is toward the start of the movie, and David is late for school and gives his game to a youngster next to him. But, later in the movie, when Jennifer asks David to fix her grade again, there is a shot in which David has two lives remaining when his ship is destroyed, but in the next shot, the game has ended.
Factual error: The beginning starts out with two Strategic Air Command officers in a Minuteman Intercontinental Ballistic Missile (ICBM) Launch Control Facility (LCF) going through the strict procedures for launch of an ICBM. The crypto messages are being received by the LCF, the launch officers pull the launch sequence and confirm the crypto launch command (encoded message) matches that which is contained in the launch sequence - all very secret, and all very realistic. However, the missile they show in the movie powering up for launch is a Titan ICBM, and how you launch a Titan from a Minuteman LCF is beyond me.
