It's been about 15 years, and I've never really worked seriously in CGI and I thought that here was an opportunity to do the kinds of things that I was not able to do on Ghostbusters.

I don't think my sense of humor has changed at all; I was born with this, for better or for worse.

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.

Movies either work or they don't work and they're either funny or they're not and we work very hard. To achieve that kind of work is really kind of delicate stitching.

When you're working with movie stars, part of the deal is that, if they have something to say, you'd better listen. You don't have to absolutely listen and not talk, but there is another creative force at work, and to be successful working with movie stars, you have to bring that force to work for you. You have to find something that's comfortable for them, and at the same time, that's in the parameters of what you're trying to do yourself.

Also watching a movie on DVD is different than watching it in the theater.

I love horror and sci-fi.
