I have always loved Bill Murray. This is a known fact. So I got that going for me you know which is nice.

What is also known is Bill is a little nutty and is making it tough to get director Ivan Reitman's planned "Ghostbusters" sequel off the ground.

"All of the actors but one have read [the script] and loved it," Reitman tells CNN of "Ghostbusters III." "We're waiting for one of them to read it and see where we are.”

Care to guess who’s not playing well with others?  “That would be the famous Bill Murray — Mr. Venkman," Reitman says of the quirky funnyman, who starred alongside Dan Aykroyd and Harold Ramis in "Ghostbusters" (1984) and "Ghostbusters II" (1989).

Reitman, 64, adds that he feels the latest installment is better than the previous two movies. "I'm really jazzed about it," he tells CNN.

And if Murray doesn't like it? “We have a very complicated deal," says Reitman. "Let's just put it that way."

Here’s hoping it all works out. This pic Bill is in character at the Spike Scream Awards. It looks too right to not happen. If it doesn’t happen it could be bad on a biblical level, Human sacrifice, dogs and cats living together... mass hysteria!
