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.

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

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

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.

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.

Whenever a critic mentions the salary of an actor, I'm thinking, He's not talking about the movie.

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

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.

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.

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.

I feel a big obligation to the audience, almost in a moral sense, to say something useful. If I'm going to spend a year of my life on these things, I want something that I feel that strongly about.

I never read Playboy before I started working there and stopped reading it the day I quit.

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

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

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.

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.

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.

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

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.

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

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.

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.

You can't not have feelings about country clubs, whichever side you're on.

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.

I used to be married to a woman who pursued every spiritual trend with tremendous passion and dragged me along. I don't believe in anything. I'd seen mediums and readers.

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

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 believe things happen that can't be explained, but so many people seem intent on explaining them. Everyone has an answer for them. Either aliens or things from the spirit world.

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

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

I'd like to think I'd never do a gratuitous fart joke.

As much as we'd like to believe that our work is great and that we're infallible, we're not. Hollywood movies are made for the audience. These are not small European art films we're making.

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

The cutting room is where you discover the optimal length of the movie.

No matter what I have to say, I'm still trying to say it in comedic form.

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?

'Analyze This' is a good movie because Robert De Niro and Billy Crystal are really good. But without the material to put on the play, of course, they couldn't be good. For me, it starts with the writing. I always think that the writer is doing the vast majority of the director's work, in a sense.

As a director on 'The Office,' there's a tremendous weight that comes with directing features. I was being asked to direct a show that had already won an Emmy for Best Comedy. Steve Carell and the cast had already won the Screen Actor's Guild Awards.

Everybody has a Bill Murray story. He just punishes people for reasons they can't figure out.

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 always point out to my Passover guests that the Hebrews were not living in isolation. They were at the crossroads of several great, elaborate cultures with their own mythology and religion and art and architecture and cultural belief. In fact, so many of the mythologies of the world describe the same events, just from different points of view.

I can't imagine a successful comedy movie without a successful comedy performance at the heart of it.

I had this 'War and Peace' thing of wanting to experience war as a kind of incredible human enterprise. I even applied to Officer Candidate School. Then the practical side of me kicked in and I thought, 'I really don't want to get drafted.' So I went down to the physical and checked every psychological disorder and drug on the medical history form.

I really only worked for about a month on 'Meatballs.' What happened was that Ivan Reitman figured out that studios wanted to meet everybody involved with 'Animal House' except the producer. So he thought he'd better start directing.

I was raised Jewish and fully embrace the core beliefs of Judaism - the ones that I identify as core beliefs, which are essentially freedom and justice. But the supernatural aspects of religion were never important to me.

I would remake 'Club Paradise.' I thought the story was cool, the setting was great. Everything lined up, except I wrote it for Bill Murray and John Cleese.

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.

If the only ideas you had were your own, you'd be very limited.

The best description of the Old Testament that I heard was that it starts out as mythology, then it becomes legend, then it becomes history. In the mythological period - there is a distinct mythological period in the Old Testament, where the time spans are impossible and really just imagined.
