Twilight is part of this movie even if you didn’t intend it, in the way it brings attention to the movie and just the fact that Summit is releasing it. How has that worked for you?
When we cast him Twilight wasn’t out, and I didn’t know who he was. That was an advantage, because I cast him just because I liked him. We hope people will go to this movie who might not have pursued it otherwise. If he wasn’t this phenom, you wouldn’t automatically assume that tens of thousands of teenage girls would show up the first day. We hope that is the case. But this is a movie I made for adults.

When did you realize you had the biggest star in the world in your movie?
Certainly the first day, when we had the thousands of girls standing outside from dawn until dusk. We realized what we were in for. It was not easy, believe me.

We understand there was one day where you snapped at the paparazzi?
We found ourselves in a situation with the movie that we never expected to be in. No one had an idea that basically we had unleashed Elvis. It was tough from the very beginning. All of us were a little gobsmacked by this. We just struggled the best we could. That was just a day that I felt the sense of entitlement the paparazzi had, that they had the right to demand certain kinds of shots. We were just trying to make the day, the sun was falling, the last shot that we did, that was it. They were angry they couldn’t get a shot of him. They felt it was their right, that we should accommodate them. I lost it, and they deserved it. They deserve worse. That was the one time I couldn’t hold back. What inspired you to cast Rob to begin with?
We needed someone who could embody a certain kind of angst that one feels at 21, and the complications and complex relationships that grow from the confusions of being 21. And Rob seemed in our initial meeting to understand that and grasp that, but have enough distance on it to be able to act that.
