It's like the old rule-if you introduce a gun into the first act of a play, it's going to be used in the third act. So if you do a movie about criminals, you have to accept there's going to be Some action.

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.

My first few films were institutional comedies, and you're on pretty safe ground when you're dealing with an institution that vast numbers of people have experienced: college, summer camp, the military, the country club.

My job is to come up with something that you like and you agree with that you would play wholeheartedly. If we disagree, I may not be doing my job correctly.

That's one of the great things about DVD: In addition to reaching people who didn't catch the movie in theaters, you get to have this interaction of sorts.

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.

There's a personal story of my own that I will write at some point, and it's a film that I will happily make. It could very well be the next thing I do, unless someone shows me something great.

We were tremendously encouraged by the testing of Analyze That. Audiences loved it. They were telling us that they liked it as much as the original. We recorded the laughs in the theater.

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.

You just make sure you don't screw it up. It's going to work as long as you don't mess it up. Hopefully you have plenty of those moments in a big comedy.

I never work just to work. It's some combination of laziness and self-respect.

We all wish we could be in more than one place at the same time. People with families feel guilty all the time-if we spend too much time with our family, we feel we're not working hard enough.

A psychologist said to me, there are only two important questions you have to ask yourself. What do you really feel? And, what do you really want? If you can answer those two, you probably can leave your neuroses behind you.

My characters aren't losers. They're rebels. They win by their refusal to play by everyone else's rules.

Nothing reinforces a professional relationship more than enjoying success with someone.

Acting is all about big hair and funny props... All the great actors knew it. Olivier knew it, Brando knew it.

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

How one handles success or failure is determined by their early childhood.

I always claim that the writer has done 90 percent of the director's work.

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