Tron is a 1982 science fiction film by Disney. It has a distinctive visual style, as it was one of the first films from a major studio to use computer graphics exclusively.
You might recall that the Master Control Program (MCP) is the main villain of the movie. It was a rogue artificial intelligence that ruled over the world inside ENCOM's mainframe computer. During the rule of the MCP, many programs were enslaved and forced to play games against its henchmen, led by Sark. Memorably, the MCP would end most of its conversations with Dillinger and Sark with the phrase "End of line".
