Trivia

The crowd voices during the disk battle in the beginning of the movie are actually the voices of the audience during the panel for the film at the 2010 San Diego Comic-Con. The audience was instructed to stomp and chant to prompts shown on the large video screen, and the sound was recorded by techs from Skywalker Sound.

Early drafts of the script did not feature the role of Alan Bradley. It was only after public outcry by Bruce Boxleitner and fans of the original film that Bradley was added to the script. Boxleitner's performance proved so popular, he went on to make public appearances as Alan Bradley to promote the film, and returned to play the role of Tron in Tron: Uprising (2012).

The suits worn by the actors proved to be problematic on set. Every single one of them was fitted with a small lithium battery that powered the circuitry for the embedded light strips, but each battery only lasted 12 minutes. In order to maximize the output, the light strips had to be switched on right before each take and turned off immediately afterwards. The circuitries inside the suits were also very fragile, so the actors could not simply sit between takes but had to recline against upright boards.

In an interview, Jeff Bridges noted that as he was being scanned by laser into a computer (for CGI effects), he realized the same thing happened to him (fictionally) in the original Tron (1982).
