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

You can perceive life as tragic, or you can laugh at the tragedy of it and that turns it into comedy. It doesn't change the circumstances.

I've always had that overweening desire to be liked by the audience.

I'd rather do comedies that strike at some bigger ideas.

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. You're always going to have some new invented technology, some pseudo-science that sounds right because we drop enough familiar terms from physics and engineering, and pseudo-methodology, something that people will think they may have read something about before.

The child says, "Well geesh, the institutions that I'm supposed to respect - the church and the government - they're telling me things that don't appear to be true. Either I'm crazy or they're crazy." That creates the Absurd Child. The Absurd Child is one who says, "Well, I think they're crazy." So you live in this state of alienation from your culture and your society and your family because you see this rampant bullshit around you.

I'm terrified beyond the capacity for rational thought.
