Avatar star Sam Worthington is all set to go blue again and has signed for the sequel of James Cameron's [ Images ] CGI blockbuster.

According to Entertainment Weekly, the 33-year-old actor will get digitised again as paraplegic marine Jake Sully for the 1.3 billion dollar grossing film.

In fact, writer-director Cameron has revealed that he's had plans for a sequel even before the flick was released December 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,' Us magazine quoted Cameron, as saying.

'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. It''d be a waste not to use it again,' added the Titanic [ Images ] director.

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