I think Junior is certainly a science fiction premise as is Twins, as is Dave, beyond 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 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.

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.

Then my first film was something called Cannibal Girls, which sounds like a horror movie but was actually kind of a goofy comedy with horror elements. Like a horror spoof.

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.

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