Random Trivia For This Title:
- The building featured as Flynn's Arcade in TRON was in reality the historic Hull Building in Culver City, CA. As of 2009, when this sequel was made, the location looked very different from its appearance in the original film. So, the movie makers opted to painstakingly recreate the original interior and a portion of the exterior in Vancouver instead, with the rest of the location filled in with CGI. The exterior even includes the "Space Paranoids" billboard on the roof, but with the addition of the "TRON" logo - in-universe, TRON is an arcade game that Flynn created after the events of the first movie.
- Before Garrett HedlundGarrett Hedlund was cast as Sam Flynn, other actors considered included Chris PineChris Pine, Ryan GoslingRyan Gosling and [?] Michael Stahl-David.
- Cillian MurphyCillian Murphy's character Edward Dillinger II is meant to be the son of Edward Dillinger (David WarnerDavid Warner), the primary antagonist of the first film who stole credit for creating Kevin Flynn's video games. He appears in only one scene. His uncredited appearance is meant to hint at a possible sequel.
- Jeff BridgesJeff Bridges (Kevin Flynn / Clu) and Bruce BoxleitnerBruce Boxleitner (Alan Bradley / Tron) are the only actors to appear in both TRON and TRON: Legacy.
- Shooting the film lasted only 64 days. Post-production, due to the heavy special effects, required 68 weeks.
- Sam's childhood bedroom features a poster for The Black Hole (another film from the same era as TRON, and a similar Disney foray into science fiction with cutting-edge at the time special effects, including computer animation). Director Joseph KosinskiJoseph Kosinski's next project is a remake of The Black Hole for Disney. The film also ties into the history of the [TRON] films because originally, for the first film, Disney wanted proof that Steven LisbergerSteven Lisberger could not only direct, but proof that the lighting effects to have the live action characters glow worked. Disney lent Lisberger and his company props and costumes from The Black Hole (which had recently wrapped) to use for their test film.
- 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. Olivia WildeOlivia Wilde had to do 12 fittings for her outfit as she had problems in movement and rehearsing her stunts.
- To play the computer program CLU, Jeff BridgesJeff Bridges' face was "de-aged" with the same technology used on The Curious Case of Benjamin Button to "age" Brad PittBrad Pitt. Thus, in his role as Flynn, Bridges appears to be his actual age of 61, but as CLU (a program written back in the 1980s) he looks like he's in his 30s - programs don't age. In order to retro-age Bridges to a 35-year-old, the actor had to wear a special helmet fitted with 4 strategically placed cameras enabling every textural nuance of his facial expressions to be recorded for precision synthesis during digital processing. In an interview, 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.
- Olivia WildeOlivia Wilde is the only actor in the film playing a program who doesn't wear contact lenses for their role due to the natural intensity of her eyes. This is not including CLU or TRON who are created in the images of their users.
- WILHELM SCREAM: A digitized or derezzed version of the scream can be heard as Sam Flynn (Garrett HedlundGarrett Hedlund) kills the last guard before entering the flying ship's cockpit.
- According to Beau GarrettBeau Garrett, the makeup time required for each actress playing the Sirens is between 3 to 5 hours, while removing them takes only 90 minutes. The only major difference between the suits for Sirens than the suits for other programs is that a layer of balloon rubber is added on top of the existing suits.
- When standing over the board game with black and white stones, Quorra mentions to Sam Flynn that she rarely beats Kevin Flynn at it. The board game is, in fact, 'Go', a game that is notoriously difficult for computer programs to play well. Unlike chess, where computers are able to beat the world's best human players, the best Go computer programs only manage to reach an intermediate amateur level. Which explains why Quorra, being a computer program, would rarely be able to beat Kevin Flynn.
- A notable absence in this sequel are the tanks, but you can still see a sort of cameo by one of them in the background when Sam returns to the city in the vintage light-cycle.
- At Comic-Con 2010, this movie became the first film to be promoted at the annual con for three years running.
- Neither Olivia WildeOlivia Wilde (Quorra) nor Garrett HedlundGarrett Hedlund (Sam Flynn) were born when the original TRON was first released.
- Sam's (Garrett HedlundGarrett Hedlund) meeting the 4 sirens just before the Grid arena was not in the script but came out during rehearsals and was choreographed into a robotic-like manner.
- When Kevin, Sam and Quorra board the Light Jet on the flight deck, and Quorra is making the jet lift off to escape, Kevin says to her "You got this, Quorra. It's all in the wrists". In the original TRON, after Kevin has beaten the video game Space Paranoids record at the arcade, he gets asked by an unseen man "Hey Flynn, how'd you do it?". He answers "It's all in the wrists".
- Hidden Mickey Mouse: the security camera Sam Flynn takes out in the Encom building has a striking resemblance to the infamous Disney mascot.
- Most expensive film ever made by a first time director, with a production budget of 170 Million US dollars. The wardrobe budget alone for this film was $13 million. One custom suit alone for the racers cost $60,000.
- Michael SheenMichael Sheen drew inspiration from [?] Mae West and Ziggy Stardust (a persona of singer David BowieDavid Bowie) for his performance. Sheen himself is a very big fan of the original Tron and when he was offered the role of Zuse he wanted to immediately accept the role. Sheen's agents didn't want Disney to find out that he wanted to be in the film badly, because then Disney could get away with paying Sheen an incredibly low sum of cash for his acting.
