We watch movies about all sorts of things that we don't know anything about, but we do get caught up in the human drama.

A good actor is someone who knows how to take the part and make it real and make it honest and be effective in it. If it's in a funny movie and, as long as they are cast in an appropriate way, humor will come from it.

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 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.

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.

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

Movies either work or they don't work and they're either funny or they're not and we work very hard. To achieve that kind of work is really kind of delicate stitching.
