Sam Worthington has said that work will begin on Avatars 2, 3 and 4 towards the end of 2014.
The 37-year-old actor told the Fitzy and Wippa show on Nova FM that the screenplay is still written, and when the cameras do roll they are going to film the three sequels back to back, Metro.co.uk reported.
His comments come after reports surfaced that Arnold Schwarzenegger is set to join the Avatar cast in an antagonist role.
According to Latino Review, the 66-year-old actor's part has been described as a "bad guy human general." (ANI)
