She sounds pretty hopeful that Ghostbusters 3 will happen and describes her Vamps character.
In an extensive interview with ShockTillYouDrop.com , Sigorney Weaver says that she’s very hopeful that Ghostbusters 3 will happen, and that she will be in it:
“I got a call from Ivan Reitman. I think everyone who’s involved would love to get together again. I think everyone’s working on really trying to create a wonderful original story. I just said, ‘That would be fun and please make sure my little son Oscar grows up to be a Ghostbuster.’ And he said, ‘Absolutely.’ Then I think he directed this other film and is busy editing it, so it kind of got put on hold. But I would be surprised if we didn’t do it.”
She also describes her character in the new vampire romantic comedy, Vamps :
“In Vamps , I play this rather awful vampire in this Amy Heckerling [directed] comedy. She’s kind of this delicious throwback to the old-fashioned vampire who really does enjoy doing what she does.”
And death may not bar a comeback for her character, Grace, in Avatar 2 :
“[James Cameron] has [talked to me] a little bit, but I’m not at liberty to tell anything. He just said, ‘You know, in science fiction, death is not really death.’”
