It looks as though Sigourney Weaver knows exactly what is going to happen in the new Avatar movies, as she has revealed that her character will "transform" in the upcoming three films.
Weaver, who is set to star in the James Cameron sequels, which will be shooting back-to-back, has spoken to Vulture magazine about her role as Dr Grace Augustine.

"It will be challenging for me," she told the magazine.
"I can't talk about it, but my part is a little different in each one. I'll transform somewhat."
It was thought that Augustine was killed off in the 2009 hit blockbuster, but according to Weaver she'll be back for the three new instalments.
Already confirmed for the follow-up movies are Sam Worthington and Zoe Saldana, which will start shooting in 2015.
