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 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.

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 never like to do parodies. I never do. It’s just not my style of comedy.

The hardest thing for everyone, for the writer, for the director and certainly for the actors, is not to panic when they’re doing a certain line for the tenth time because everything ceases to be funny after it’s been repeated.

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