My first student film was Orientation, which was basically the set-up for Animal House. There are a couple of scenes that we later borrowed in some form.

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.

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'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.

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

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