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

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.

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

I think if people want to see pure sex in the movie, they have the Internet and the extraordinary things are available.

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

I believe that improvisation is really just a directorial tool. It's a writing tool. It's not so much that the actors get to say whatever they want, whatever pops into their head. It's an opportunity to write the last draft of the screenplay as you're working on it.
