Everyone’s favourite alien-bashing action heroine Sigourney Weaver has spoken out about two forthcoming blockbuster sequels she’s attached to. Depending on how cynical you’re feeling, the news that she’ll be returning to the verdant CGI jungles of Pandora for the two Avatar sequels should come as no surprise, despite the fact that her character Dr. Grace Augustine (I’d say spoiler alert here, but seriously, who hasn’t seen Avatar?!) died in the first film.

“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.”

The sequels will reportedly be shot back-to-back beginning next year, with the first targeting a December 2014 release and the next film following a year later.

Somewhat less encouraging is what Weaver had to say about the highly anticipated Ghostbusters 3, in which it is hoped she will reprise her roll as Dana Barrett.

“I have yet to read the script. I’ve had a couple of calls and I know they’re rewriting and all I said was that I hope my son, Oscar, has grown up to be a Ghostbuster and Ivan Reitman said yes. Beyond that, I have no idea. I hope it comes together, but we already did two wonderful films and, if we have to let this one go, that’s fine.”

The main stumbling block for Ghostbusters 3 appears to be whether Bill Murray will be involved in the project. The actor has previously said that he does have a copy of the script but has yet to read it, while Dan Aykroyd recently announced that it’s looking likely the film will go before cameras in spring 2012 with or without Murray.
