Tron (1982)

Tron directed by Steven Lisberger, is about a hacker/arcade owner how gets trapped inside one of his own games by a software pirate called Master Controle. In here he meets up with a guy called tron and they join forces to defeat the Master Controle in an infinitely challenging computer game.

Although this film was the beginning for computer animation and the first movie to extensively use 3-D computer graphics, it was a flop at the box office and was disqualified of winning an Academy Award for special effects because at the time the Academy thought that it was 'cheating' using the computer.

A fun fact about the movie is that to inspire the actors/actresses they placed arcade games on the production set and could be played during downtime. Also the name 'Tron' is actually a basic programmers command which means to 'TRace ON'.
