Daft Punk composed the musical score, incorporating orchestral sounds with their trademark electronic music. Chroma keying and other techniques were used to allow more freedom in creating effects. Most sequences were shot in 3D and ten companies were involved with the extensive visual effects work. Principal photography took place in Vancouver over 67 days, in and around the city's central business district. As he was not optimistic about Disney's Matrix-esque approach to the film, Kosinski filmed a high-concept, which he used to conceptualise the universe of Tron: Legacy and convince the studio to greenlight the film.

Kosinski was recruited as director two years later. After much speculation, Walt Disney Pictures began a concerted effort in 2005 to devise Tron: Legacy, with the hiring of Klugman and Sternthal as writers. Interest in creating a sequel to Tron arose after the film garnered a cult following. The story follows Flynn's adult son Sam, who responds to a message from his long-lost father and is transported into a virtual reality called 'the Grid', where Sam, his father, and the algorithm Quorra must stop the malevolent program Clu from invading the real world. The cast includes Jeff Bridges and Bruce Boxleitner reprising their roles as Kevin Flynn and Alan Bradley, respectively, as well as Garrett Hedlund, Olivia Wilde, James Frain, Beau Garrett and Michael Sheen.

It serves as a sequel to Tron (1982), whose director Steven Lisberger returned to produce. Tron: Legacy (stylized as TRON: Legacy) is a 2010 American science fiction action film directed by Joseph Kosinski (in his feature directorial debut) and written by Adam Horowitz and Edward Kitsis, from a story by Horowitz, Kitsis, Brian Klugman, and Lee Sternthal.
