The stand-up comedian-turned-actor has recently appeared in the family movie series "Madagascar" and most recently the art house film, "Two Days in New York," about a couple who finds coping with family a trying experience.

"They're all kind of PG-type things," he said, referring to his recent movies' ratings. "So it would be kind of nice to get up there and curse up a storm and have some fun. I am writing all the time. I got a ton of nasty stuff."

But Rock did say he has turned down some roles because of their content. "I've turned down a couple of things like pimps. ... Somebody had - I'm not going to say his name - had the rights to 'Super Fly.' It's like, 'We can do it on Broadway.' I was like, 'Dude, I'm not -- I don't need money that bad. I don't want to make -- I got daughters. I can't produce a pimp musical.'"

As for his stand-up comedy, Rock said he's not the same as in his movies when he's on stage.

"In stand-up, I'm Leo(nardo) DiCaprio," he said. "I get to play what I want to play. I can go wherever I want to go. I'm Leo. Leo gets the best scripts. 'Hey, hey man. Leo is coming.' Everybody knows that Leo is getting the best."
