I collect spores, molds, and fungus.

I've always thought that comedy was just another dramatic expression. I try to measure the amount of truth in a work rather than just looking at the generic distinction between comedy and drama. There's a lot of bullshit drama that leaves you totally cold. And there's a lot of wasted comedy time too. But when you get something honest, it doesn't matter what label you give it.

First and foremost, you have to make the movie for yourself. And that's not to say, to hell with everyone else, but what else have you got to go on but your own taste and judgment?

The comic impulse is sometimes a reaction to sadness. You feel like you can make one choice or the other.

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.

The times change, and to the extent that comedy captures the spirit of the times, it will enjoy success.

I've been directing for 25 years almost, and I've only directed nine films in that time because I like to be careful.
