Sigourney Weaver, while out promoting Avatar, made headlines today by revealing some of the plot for the upcoming blockbuster GHOSTBUSTERS 3. She revealed potential new details of the planned film which have subsequently caused a stir of excitement. All Ghostbuster fans you've been warned, if you hate spoiler news don't continue...

Follow up:

"I'm afraid to say it [Ghostbuster 3] is happening, I hope people are excited about that," she said. "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.'"

"I know that my little son Oscar – who was kidnapped from me – I think he has grown up to be a ghostbuster," she added. "I might be in it; 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."

I can see writers Lee Eisenberg and Gene Stupnitsky slapping their foreheads now as, no doubt, they wanted to keep this a secret.

Venkman as a ghost? What do you die hards think of this news?
