James Cameron is deep in pre-production for his next three Avatar movies, and far as actors go, right now it stars Sam Worthington, Zoe Saldana, and Stephen Lang, and there's even a rumor that Arnold Schwarzenegger will be a part of it. It was a safe bet to assume that Sigourney Weaver would be a part of these sequels, and now she has confirmed it in an interview with Vulture. She even talks a little bit about what we can expect from her character saying,
"It's going to be an adventure! 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. 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."
It's interesting how she talks about her character transforming from one movie to the next. In the first movie her character failed to link up with the "Tree of Souls," but maybe there is something on the planet of Pandora that helps them resurrect Dr. Augustine in some way? It's not out of the realm of possibility in a fantasy sci-fi film like this. Whatever happens with her character, it will be great to see Weaver return.
