When someone's an actor and you're an actor, you meet them and you feel like you know them. We're in the same business, and we all speak the same comedy language.

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.

I had a lot of fun working with John Candy. We had a pretty good rapport.

Somebody once told me that if you laugh at a George Bush joke, or you send an email cartoon to your friends that makes Bush look like a fool, you feel like you've done something significant. But really, what have you actually done? Just expressing contempt for your leaders doesn't really accomplish anything.

Multiplicity was a movie that tested really well. People seeing the movie really liked it, but then the studio couldn't market it. We opened on a weekend with nine other films.

I'm not a believer in the pratfall. I don't think it's funny just to have someone fall down.

It doesn't take any longer to improvise 10 takes than it takes to shoot 10 takes of the same thing. It turns out to be just as responsible from a business point of view as anything else.
