By now, we all know that Bill Murray has the Ghostbusters 3 script sitting somewhere near his desk, yet he hasn't bothered to read it. Will that happen anytime soon? Who knows? But Ivan Reitman has revealed that it will be his next directorial assignment should Bill Murray ever pick it up, peruse it, and actually like it.

"There's a lot of talk about Ghostbusters 3. And there's a very good script that the other cast members have read and liked. We're just waiting for Bill Murray to read it."

Ivan Reitman also gave an update on the long-gestating big screen reboot of Baywatch.

"We still don't have a script that's makeable. I think it's a big opportunity. This is a comedy, and I think we have a very interesting take - a classical idea that will be fresh for the world audience. It's one of the best-known titles that's out there."

The director also spoke on the possibility that he will move forward on a sequel to Howard Stern's Private Parts.

"I spoke to Howard. He brings it up all the time. There is a great sequel story in it. But I doubt it will happen. If he's going to do another film, my guess is that it's probably not going to be the sequel to Private Parts."

Lastly, Ivan Reitman revealed that he does plan to someday co-direct a movie with his son, Up in the Air director Jason Reitman.

"He's just finished directing Young Adult for Paramount. Not for us. It was a small film he did on his own. I think he is establishing his own company, which is healthy for both of us. I'd like to direct with him somehow. I'm talking about a movie we would co-direct that has a kind of dual story perhaps that can be divided up."
