Now that talk on a possible, long-gestating Ghostbusters sequel is heating up, MTV spoke to Sigourney Weaver about her potential involvement (when will someone call Peter MacNicol? We're dying over here!). Weaver admitted that she's supposed to call Bill Murray next week about the project, adding, “I would hope that my little [movie son] Oscar would be one of the Ghostbusters even if I’m not in it!” Careful, Sigourney — you're giving producers some Seth Rogen casting suggestions. Weaver also revealed that she's been talking to Ridley Scott about a potentially radical overhaul of the Alien franchise:

She asked aloud “whether there’s unchartered territory for a creature who’s become somewhat debased by this computer generated thing. I haven’t seen ["Alien Vs. Predator"] but I just think if you overexpose the creature, that’s a mistake.”

Weaver confirmed that she and Scott have discussed re-teaming for a fifth film, “Both of us feel a kind of commitment to that woman. He’s as much responsible for who she is as I am.” Then as she opined on the way the alien creature had been ruined in the recent films, Weaver’s comments got especially interesting.

“We’d have to go back to the drawing board on [the alien],” she said. “Ridley said that right away when we first talked about [a fifth film].”

And finally, the quote that’s gotten me mighty curious, “What we’re interested in is taking the character of Ripley and seeing what other science fiction story we can tell about someone who has lived several lives.”

Though purists may blanch at the idea of an alien-less Alien sequel, we agree that there are plenty of stories left for Weaver's indomitable central character. In particular, we're looking forward to RIPL-e, in which Ellen Ripley, tasked with garbage management on a far-off planet, must overcome her longtime distrust of androids when she falls in love with an adorable (and tasty!) iPod.
