Sam Worthington Signs on for Avatar Sequel

Sam Worthington is going blue again for Avatar's sequel.

The 33-year-old actor, who stars in writer-director James Cameron's $1.3 billion grossing CGI blockbuster, will get digitized again as paraplegic marine Jake Sully for the film's follow-up, Entertainment Weekly reports.

And as Worthington signs on the dotted line, Cameron reveals he's had plans for a sequel even before the flick was released Dec. 18.

"I've had a story line in mind from the start -- there are even scenes in Avatar that I kept in because they lead to the sequel," Cameron, who also helmed 1997's Titanic, tells EW's new issue, on stands Friday.

"It just makes sense to think of it as a two-or-three-film arc, in terms of the business plan. The [computer generated] plants and trees and creatures and the musculoskeletal rigging of the main characters -- that all takes an enormous amount of time to create," he adds. "It'd be a waste not to use it again."

Avatar is up against The Hurt Locker, Inglorious Basterds, Precious and Up in the Air for Best Picture at Sunday's Golden Globes.
