Life doesn't care about your vision. You just gotta roll with it.

If you're doing six takes, instead of doing six variations on the same words, why not just throw out the words and make them up as you go along, if you're comfortable with it? It gives the movies a slightly rangier feeling, and more of an accidental feel, but it also makes them edgier.

When I've written for Bill Murray - I've written six films for him - people would read it and say, "Oh, that's so perfectly Bill." He'd read it and say, "Are you kidding? I can't say these words." So it's all about perception.

As an actor, you're completely at the mercy of other people. You basically go begging for the opportunity to work. As a writer, at least nobody can tell me what to do. I can write what I want. I might not sell it, but at least I'm in control.

The first comedy screenplay that I wrote was Animal House and I always thought I could and should be a director but no one was about to give me that opportunity on Animal House.

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.

I did a comedy with Al Franken about his character Stuart Smalley, which was really about alcoholism and addiction and codependency. It had some painful stuff in it. When we showed it to focus groups, some of them actually said, "If I want to see a dysfunctional family, I'll stay home."
