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 love horror and sci-fi.

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

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.

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

When you're working with movie stars, part of the deal is that, if they have something to say, you'd better listen. You don't have to absolutely listen and not talk, but there is another creative force at work, and to be successful working with movie stars, you have to bring that force to work for you. You have to find something that's comfortable for them, and at the same time, that's in the parameters of what you're trying to do yourself.

I think if people want to see pure sex in the movie, they have the Internet and the extraordinary things are available.
