Sigourney Weaver might want to check her inbox. I’m pretty certain Sony would’ve emailed over a cease and desist for her. They’re probably – speaking from experience here – looking for a prompt reply, too.

What’s all this about? It’s about this - that’s what!

Sigourney dropped a huge “Ghostbusters 3″ bombshell today while plugging “Avatar” (see my review here). According to the actress, who will likely be playing a small role in the pic, co-star Bill Murray will be playing a ‘Ghost’ in the upcoming second sequel to the 1984 hit!

Yeah, you heard right -it’s ‘Venkman’ that the Ghostbusters (new and old) are likely going to have to ‘Bust’ this time ‘round!!

So crazy… it might just work!
