Tron is a 1982 American science fiction film written and directed by Steven Lisberger, and released by Walt Disney Pictures. It stars Jeff Bridges in a dual role as the protagonist Kevin Flynn and one of his programs, "Clu" (who would reappear 28 years later as the main antagonist in Tron: Legacy); Bruce Boxleitner in a dual role as security program Tron and Tron's "User", computer programmer Alan Bradley; Cindy Morgan in a dual role as program Yori and her "User", Dr. Lora Baines; the late Barnard Hughes in a dual role as the tower guardian Dumont and his "User", Dr. Walter Gibbs; Tony Stefano in a dual role as Ed Dillinger's secretary Peter and Sark's otherwise-nameless Lieutenant; and Dan Shor as Ram. David Warner plays all three main antagonists: the program Sark, his "User", Ed Dillinger, and the voice of the artificially intelligent Master Control Program. The movie also features cameo roles by Jackson Bostwick of Shazam! fame (as a guard program) and a pre-American Ninja Michael Dudikoff (who makes his acting debut as a video game-conscript).
