It seemed like so much of romantic relationships today have to do when the people are not in the same room. Whether it's texting or emailing or Facebooking, there's a kind of distance between the participants. I think it's sort of shifted the energy of that first romantic meeting, where it's quicker, perhaps more desperate, more energetic, in a whole different way, and it's resulted in a situation where people seem to be sometimes more comfortable having a sexual relationship than an emotional one.

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.

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.

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.

I'd always been a science fiction enthusiast.

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 don't think my sense of humor has changed at all; I was born with this, for better or for worse.
