We are all several different people. There are different aspects of our nature that are competing.

I'm thinking of doing a marital comedy for one of the studios, but I want it to be so painful that it'll have a profound effect on married couples who see it together.

I want to explore marriage without the usual Hallmark Card platitudes. Life is difficult, and I like movies that acknowledge that.

If Chevy Chase had not been an actor, he might have been a very popular guy in advertising or whatever field he would have gone into, because of his charisma.

Films are big hits when they touch a lot of people. Things are not funny in a vacuum, they're funny because we respond to some personal dislocation, some embarrassment, some humiliation, some pain we've suffered, or some desire we have.

I'm a writer-director-actor, which I've always kind of enjoyed. I compared it to the Olympic biathlon. "Not only can he cross-country ski, but he's a terrific marksman as well." I want people to say, "You mean that writer performed a tracheotomy?" That's right, I do everything.

The trick with sequels is, you have to give people what they liked before, yet be innovative enough so they don't feel like they're seeing the same movie.
