The Hollywood Reporter is reporting that both Sam Worthington and Zoe Saldana have finalized their deals to return in three more Avatar movies, set to film back to back to back. Stephen Lang, who played Marine Colonel Quaritch in the 2009 film, is already signed on to return, though his character died in the first film so it will be “interesting” to see what plans James Cameron has for him.
The first sequel will hit theaters in December 2016, with the second to follow in December 2017 and the third a year later.
