If you've been following the ever-increasing rumors revolving around 'Ghostbusters 3,' you know the drill. There's a script written by Lee Eisenberg and Gene Stupnitsky ('Year One,' 'The Office'), and pretty much everyone is eager to jump back into the supernatural world for a bit before handing over the reigns to a new crop of ghostbusters. That is, everyone except Bill Murray.

Most of the rumors and news items about the film have focused on Murray because the actor isn't so keen on returning to the world. So the project continues to rest in stasis, going nowhere.

Since the story is a passing of the torch, one might assume that it would be possible to do the film without Murray. But in a case of supreme studio loyalty -- and smarts, because let's face it, he's got the most star power of the bunch -- Sony won't give the sequel the green light unless Murray is involved.
