Well, actually, I did start out in comedies. Very, very early.

I never like to do parodies. I never do. It's just not my style of comedy.

There's been an amazing backlash for the last decade in America: political correctness. In many ways, I think that, while we've been remarkably violent in our media, there's been a real schizophrenia. In private, on the Internet, and on public-affairs shows or talk radio, we're way more explicit than we've ever been. But traditional Hollywood has been much more frightened than it ever was in the '70s about presenting things that could be perceived as politically incorrect.

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

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.

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

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.
