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

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

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.

The home viewing experience is slightly different and there's room for these kinds of extra excursions.

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.

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.

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.
