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

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've always been a fan of science fiction films, and I've never been able to put my particular spin on it.

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.

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.

Also watching a movie on DVD is different than watching it in the theater.

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.
