SIGOURNEY WEAVER will be back in the three sequels to the hit movie, "Avatar." Producer JAMES CAMERON tells Deadline.com "Her character of Grace Augustine, as fans know, died in the first movie, so she’s playing a different and in many ways more challenging character in the upcoming films."
SAM WORTHINGTON, ZOË SALDANA and STEPHEN LANG are back for the sequels as well --even though Lang is another one of the characters who died in the earlier movie.
The first "Avatar" sequel is set to be released in December, 2016.
