, the groundbreaking 1982 adventure movie that integrated computer generated imagery into its narrative, is set to be reissued in the UK later this year in a special two-disc 20th anniversary edition.
The discs have already been released in the US and a spokeswoman for Walt Disney, Buena Vista Entertainment said the UK version should be ready by September.
The film, about a video game designer trapped inside a cyber world, is available in a remastered letterbox transfer with Dolby Digital Sound. The film not only pioneered the use of computer animation but linked it to live action.
The edition features a commentary by writer-director Steven Lisberger and a 90-minute retrospective documentary The Making of Tron.
It also includes production design sketches and photos, a handful of deleted scenes and a collection of the film's trailers.
Tron holds the historic status as the first film to present a computer generated 3D universe. The plot follows a programmer, Flynn, who hacks the mainframe of his ex-employer to prove that his work was stolen by another executive, only to find himself on a much bigger adventure.
Beamed inside by a master control program, he joins computer gladiators on a deadly game grid, complete with high-velocity light cycles and Tron, a specialised security program.
The sequel, which is in development, goes back in time to take a different split on the freeway, according to Lisberger.
Tron's influence, which also launched a number of computer games, can be found in more recent films such as The Matrix.
