Trivia, insights & behind the scenes
This film literally changed policy — Reagan watched it and asked his general if this could happen, leading to the first presidential cybersecurity directive.
The IMSAI 8080 was so loud that dialogue had to be re-recorded; Broderick's typing in the poster is completely wrong finger placement because he's actually playing the director's notes.
