TRON is a 1982 American action science fiction film produced by Walt Disney Productions and Lisberger Studios and released by Buena Vista Distribution Company. It stars Jeff Bridges as the protagonist hacker Kevin Flynn (and his program counterpart inside the electronic world, CLU), Bruce Boxleitner as Tron (and Tron's "user", Alan Bradley), Cindy Morgan as Yori (and her "user", Dr. Lora Baines), and Dan Shor as Ram. David Warner plays all three main antagonists: the program Sark, his "user", Ed Dillinger, and the voice of the Master Control Program.
Tron was written and directed by Steven Lisberger, who has a distinctive visual style, as it was one of the first films from a major studio to use extensive computer graphics. Decades after it first came out, it has spawned a franchise consisting of a sequel film, multiple video games, comic books and a planned television series.
