I collect spores, molds, and fungus.

You don't have to know much, just a little bit more than everybody else.

The comic edge of Ghostbusters will always be the same. It's still treating the supernatural with a totally mundane sensibility. In the world of ghostbusting, there are certain givens.

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

At a certain point, you have to convince the actors that you've done the right thing. The way I work, if I can't convince them, I've got to move on. I can't coerce them or browbeat them.

As much as I liked acting for its playfulness and the reward of hearing big laughs wash over you on a stage, I always felt I should do something that I could control.
