Tron Legacy is still months away from hitting our screens, but in a big vote of confidence in the film’s likely success, Disney has hired the film’s writers to start work on a sequel script.

Edward Kitsis and Adam Horowitz, who have usually been spending their days writing episodes of Lost, will be locked in a spooky old arcade bought specially for the process and told they can’t come out until they’ve finished at least three drafts and found the kill screen on Missile Command. Okay, not all of that is true, but they have definitely been hired to write a Tron sequel.

Those two are the only people involved right now, especially since a greenlight for the sequel is a long way away – and is dependent on Legacy being a hit.

But Disney has retained options on the likes of Garrett Hedlund and Olivia Wilde, and while director Joseph Kosinski’s development slate is filling up with other Mouse House remake projects, we’re sure the company would be happy for him to delay those to make another virtual adventure.

There is naturally no inkling of what the plot will be, though the world of this year's film has been built to include future stories and according to the Heat Vision Blog, the writers are dreaming up trilogy ideas.

The early start means that, should Legacy hit as big as we think it might, Disney would be ready to start gearing up production on a follow-up quickly, with a likely 2012/2013 release target.
