TRON (1982)

One of the earliest feature films to reflect the video-game craze of the 1980s, Disney's Tron stars Jeff Bridges as a computer programmer who becomes part of the very game that he's programming. Bridges' principal antagonist is his glory-grabbing boss David Warner, who likewise metamorphoses into a video-game character. The title character, a computer-generated superhero, is played by Bruce Boxleitner. Though antiquated by 1990s standards, Tron represented the last word in special effects back in 1982. Surprisingly, despite its long-range influence on the movie industry, the film was a box-office disappointment when first released.
