Despite her character being killed in Avatar, it is well-known that Sigourney Weaver will be back for the highly-anticipated sequels Avatar 2, Avatar 3 and Avatar 4. Vulture recently caught up with the actress, who teased that her character Grace will "transform" somehow in the sequels.

"It will be challenging for me. I can't talk about it, but my part is a little different in each one. I'll transform somewhat. We'll have to talk again when I survive this. For now, I'm going to skittle around and enjoy this leisure time."

The actress revealed in 2012 that all three sequels will be shot simultaneously, with Sam Worthington confirming last year that production will begin in October 2014. When asked about the challenges of shooting three movies at the same time, Sigourney Weaver said that she can't even imagine yet what director James Cameron is taking on with these ambitious sequels.

"It will be awesome. I can't even imagine what I am taking on - and what James Cameron is taking on - with filming three Avatars at once, but Peter Jackson did it with The Hobbit films, so we have that to look to."
