Olivia Wilde & Garrett Hedlund on board for another Tron movie

Olivia Wilde and Garrett Hedlund have signed on to return to the world of Tron for a follow-up to 2010's Tron: Legacy.

The pair will reprise their characters from the sequel to 1982's Tron, about a computer game that comes to life.

The original was a flop at the cinema but became a cult movie; the sequel grossed $400 million worldwide.

The latest Tron will shoot later this year (15), according to The Hollywood Reporter.
