AVATAR 2 - James Cameron Talks about Bringing Back Sigourney Weaver

Despite being killed off in Avatar, Sigourney Weaver's character Dr. Grace Augustine will be back for the sequel that director James Cameron is currently developing. Weaver revealed this news in a previous interview saying that,

Don't worry, I will be back. Jim [Cameron] says no one ever dies in science fiction. He's told me the stories for the next two movies and I have to say that they're absolutely wonderful and there's a real treat in store. Now we just have to make them.

Cameron was asked about her return to the franchise in a recent interview, and kind of revealed a sensible way to bring her character back in the sequels saying,

Well, I don’t want to disabuse her of that fantasy. But have you ever heard of nonlinear storytelling? A lot happens on that planet before she shows up, and before Jake shows up to join her. She’s there for fifteen years ahead of time. I don’t know, but I wouldn’t jump to conclusions. And I’ve already said way too much about Avatar 2 and 3 here and there, but people piece it together like those voice cameos and tell the whole story!

For those of you who need a refresher, Jake took Dr. Grace Augustine body to the Tree of Souls with the hope that her soul could be transferred into her avatar form. Turns out she was too weak for the transfer to succeed. In her final moments, she told Jake that she was with Eywa. He then went on to say,

Okay, here’s the deal. When you have a science-fiction series, a science-fiction franchise, you’re never dead, unless your DNA is expunged from the universe. And then there’s always time travel!

So basically we still don't really know what exactly he has planned for the next two movies, but he'll be buried in developing them over the next five years. 

I wonder if the next two films will be just as successfull as the first one.
