Olivia Wilde (Fox's "House," pictured left) and Beau Garrett (pictured down right), who appeared together in Turistas, are the first to sign on for Tron 2.0, the sequel to the 1982 Disney cult classic being directed by Joseph Kosinski.
Sean Bailey is producing along with Steven Lisberger, who co-wrote and directed the original film, and Jeff Silver.
The original, about a programmer thrust into a computer and forced to fight in games he helped create, is remembered for its sci-fi gladiator-style battles and groundbreaking special effects.
The new movie is acting as a "next chapter." Plot details are being guarded closely, but Wilde will play a worker in the virtual world who tries to help fight Master Control Program, the villainous intelligence protocol that was the nemesis in the original film.
Garrett will play a siren in the virtual world.
The male lead has not been cast, but the studio and filmmakers are screen-testing actors as it brings on other leads and supporting players.
