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

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.

It's sort of the most important thing for acting, is to listen to the person you're dealing with.

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 love horror and sci-fi.

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

I remember when first, Stripes, and then Animal House came out - which I was really proud of, even though it was kind of loose and quite raucous - there were imitative movies that were not quite as good.
