Your best mate, the guy down the pub, even your bin man - everyone seems to know something about Ghostbusters 3. But holster your Proton Packs, because here to bust those rumours for good is Sigourney Weaver herself. Chatting to Channel 4 News about Avatar (don't act like you haven't heard about it), she let slip a few details about the much-mooted sequel.

"I’m afraid to say it: Ghostbusters 3 is happening. I hope people are excited about that. I don’t know if I’m going to be in it, I have had a couple of calls asking "would you read the script?" But what is in this script she speaks of? "I know that my little son Oscar – who was kidnapped from me – I think he has grown up to be a ghostbuster... I see nothing wrong with being in it, although I don’t think I will have a big part. I think Bill Murray has a little more to do with it - he’s a ghost."

Does that mean Peter Venkman will be the new Slimer? Keep watching the walls, folks - we'll start stalking Murray now and let you know. Unless we get arrested first.
