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

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.

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

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.

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."

Where's the great pay? Where's the travel? Where's the Winnebago, Goddamnit!

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