Trivia: Director Steven Lisberger had several arcade games scattered all around the sets. The cast and crew often had to be called away from them to return to shooting, particularly Jeff Bridges, who would often claim he was "preparing for the next scene" in order to keep playing a bit longer.

Trivia: Peter O'Toole was originally offered the part of Dillinger/Sark. He was very interested in the role, but backed out when he discovered that it would involve mostly acting against a black screen, with all the sets and backgrounds to be added digitally later on.
Trivia: As Alan comes into his cubicle, on the wall is a banner reading "GORT, KLAATU BARADA NIKTO", a nod to "The Day the Earth Stood Still".
