Disney (US) has cast Garrett Hedlund as the lead in the Tron sequel, according to The Hollywood Reporter.
Heldund is probably most famous for playing Patroclus in Troy, with supporting roles in Eragon, Four Brothers and Friday Night Lights also on his CV.
Hedlund will play the lead, a man who finds himself pulled into the world of a computer and retracing the steps of a character from the original movie named Kevin Flynn.
Jeff Bridges is reprising the role of Flynn, while Bruce Boxleitner, who played the title character, is returning as well. Olivia Wilde and Beau Garrett have also been cast in the project, which starts shooting in the spring.
