I call it like the domino theory of reality. If you can go one step at a time and it seems to make sense, you can then take your audience into an area that is relatively outlandish.

I always thought that Bill Murray was one of the great actors that I've worked with. And I've worked with all kinds of people who are known primarily for their dramatic work.

I've always believed in populating my films with characters who we like, who we have some warmth for, who have warmth for each other, who we would like to hang out with, who we emulate in one way or another. It's not that they all get along, or that there aren't bad people or people we make fun of. But at the core, there's a kind of sweetness.

I think Junior is certainly a science fiction premise as is Twins, as is Dave, beyond Ghostbusters.

I don't think there will be another Ghostbusters. I think we're all too old to do it. I think we've done it a couple times and there is not that much to get out of it, to do that would be fresh in it.

Everybody says how hard comedy is, but, when it comes time to honor things, whether it's on a weekly critical basis or whether it's award time, at that time of the year, comedy is the poor, dumb child of dramatic work.

A good actor is someone who knows how to take the part and make it real and make it honest and be effective in it. If it's in a funny movie and, as long as they are cast in an appropriate way, humor will come from it.
