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.

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

I've got to find a compromise where I don't feel compromised. I've got to find something equally good that they don't feel uncomfortable with. At a certain point, it's no longer about what I thought was right, but it's about this new discovery that happens with the actors. It's nice when the actor is also a writer.

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

Ive never been a big believer in ghosts or the spirit world, and for me, that was part of the point of the movie, ... What the Ghostbusters represented was the triumph of human courage and human ingenuity. People create their own monsters. Our fears come from within us, not outside.

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

I think of myself as a real writer, not just someone who dabbles in it, so I deserve some credit.
