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.

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'd always been a science fiction enthusiast.

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 been a fan of science fiction films, and I've never been able to put my particular spin on it.

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.

My sense is, I think it's okay for directors to do movies that speak to other work in their career.
