And just like that, the Ghostbusters 3 momentum stops.

At the red carpet for the premiere of The Fantastic Mr. Fox in London, Bill Murray was asked about why he decided to get involved with Ghostbusters 3. His answer: he hadn’t yet, as there is no script.

“I don’t want to do it yet,” he said. “Until there’s a really good script I’ll stay home and play snooker. There has to be a serious script before I leave the house. I won’t make one just to make another one.”

And he’s not holding his breath, either:

“I’ll believe it when I see. I saw a guy talking about the end of the world a couple of years ago and I haven’t seen that either. I’ll believe it when I see a script.”

To this intrepid web pundit this reads like Bill pumping the brakes a bit. While he’s open to the idea of a Ghostbusters 3, he’s very much script-dependent, and getting a script together will likely be the hardest part of the process. While Dan Aykroyd and Sony may very well be willing to go in front of cameras with a half-assed screenplay (thinking they can fix it as they go), Murray’s going to demand not just a complete script, but a good one.

And by the way, Bill’s aware of Ghostbusters 2’s quality: “We made a second one, and it was okay, but it wasn’t as good as the first one.”
