For me, most comedy scripts fail in the mechanical playing-out of the setup. They'll pay lip service to a moral lesson or a psychological progression.

Ive never been a big believer in ghosts or the spirit world, and for me, that was part of the point of the movie, ... What the Ghostbusters represented was the triumph of human courage and human ingenuity. People create their own monsters. Our fears come from within us, not outside.

I have a great respect for the moviegoing experience. It's such a unique thing. You're not getting up and walking around the house or flipping channels during the dull parts. You're in a dark space, and the movie fills most of your field of vision. You're surrounded by sound, and the colors are deeply saturated, and faces are fifteen feet high. If it's done well, you're really going to feel some big emotions or have some big belly laughs.

I think satire is a luxury of literate middle-class people. People who are well fed and relatively secure in their beds can laugh at their troubles. They can enjoy sitcoms. For those who aren't quite so lucky, well, the irony might be lost on them.

With both Caddyshack and Vacation, it's not like the subjects were serious enough that they engaged my interest for another round. I love the characters, and the actors were great, but I didn't see the need to make another Vacation movie.

Just expressing contempt for your leaders doesn't really accomplish anything.

Billy Crystal knows how to make people laugh. He's got 30 years on stage... there's no telling him what's funny.
