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

The home viewing experience is slightly different and there's room for these kinds of extra excursions.

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've always believed in populating my films with characters who we like, who we have some warmth for, who have warmth for each other, who we would like to hang out with, who we emulate in one way or another.

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.

I'd always been a science fiction enthusiast.

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.
