I'd always been a science fiction enthusiast.

I always see things that I can improve. But frankly with Stripes, I'm surprised at how effective it is, even today, and how vibrant that movie is and how juicy the performances all are.

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 love to do a musical actually. My background is in music. I have a bachelors in music. I thought that I was going to be a composer, long ago when I first started. So it was amazingly fun to do those two routines in the film.

I'm not sure I agree with the thesis, because I think that even though something grotesque or gross has been part of film since way back, what we accept or what we can get away with on the screen is broader now.

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.
