I have "Tron" on DVD. I saw it when it first came out in the theaters and was in awe of the special effects. Special effects that, by today's standards, would be considered lame. It's one of the movies that first got me hooked on science fiction movies and television series.

A hacker (Jeff Bridges) is digitized and abducted into the world of a computer by the MCP (Master Control Program) and forced to participate in gladiatorial games where his only chance of escape is with the help of a heroic security program called "Tron" (Bruce Boxleitner). Every character is played twice in this movie, but David Warner gets triple duty as the voice of the MCP.

"Tron" stars Jeff Bridges, Bruce Boxleitner, David Warner, Cindy Morgan and more. Here's a fan trailer and a fan music video which uses a song by Eiffel 65 called "Blue (Da Ba Dee)". The last one seems rather fitting.
