For those of you just being introduced to Tron or even if you're already familiar with it. Here's some information about the movie that started it all!
ABOUT TRON
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).
The film tells the story of Flynn as he attempts to hack into the ENCOM mainframe to prove that Dillinger has appropriated his work, but ends up being transported into the Digital World itself as a unique program/User. There, he teams up with Tron to defeat the Master Control Program, who has been controlling the Digital World.
