Well, actually, I did start out in comedies. Very, very early.

It's been about 15 years, and I've never really worked seriously in CGI and I thought that here was an opportunity to do the kinds of things that I was not able to do on Ghostbusters.

My sense is, I think it's okay for directors to do movies that speak to other work in their career.

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.

The real trick for me as a director is to make sure that people don't start pushing because the harder you push as a perform the less funny it becomes.

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