Was Tron based off a game?
Tron is a 1982 action video game developed and published by Bally Midway for arcades, based on the Disney film of the same name. The lead programmer was Bill Adams with Earl Vickers programming the music. Characters in Tron are set in landscapes that could not physically exist in the real world, a world where terrains and vehicles are created by computers. Although CGI was used sparingly in movies before (eg, Westworld, Star Trek, Looker) Tron was the first motion picture to make such extensive use of computer imagery.
