In an interview with the French TV show Le Grand Journal, Sigourney Weaver revealed that she and James Cameron have discussed her return in the Avatar sequel. But wait, you may be thinking (and the following is spoiler-y if you're one of the dozens of people left who hasn't seen Avatar), didn't she die after the Na'vi tried to transfer her from her human body into her unanimated Avatar? That's right! You have a good memory. But Weaver had a bit of an explanation for that, saying that her character still exists "in the tree," whatever that means. We'll admit that we're a little skeptical of this idea, but at this point Cameron has earned the ability to do pretty much whatever the hell he wants.
