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.

We got some devastating reviews on Animal House at the start.

I don't think there will be another Ghostbusters. I think we're all too old to do it. I think we've done it a couple times and there is not that much to get out of it, to do that would be fresh in it.

In a comedy it helps enhance things that were already there.

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.

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.

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