I came from advertising. For me it's about protecting the director's vision. That's always the goal. There's keeping things on budget and on time and dealing with selling the movie so that to me is a focus. But also it's about serving the script. We are genre filmmakers, those are the films we love to make, so my perspective is a little different.

I think that I'm a pretty great producer, but the vision behind Batman is Chris Nolan. I'm there to do my best to help execute that vision, and I think I do a really good job, but the vision is Chris Nolan.

I think that Superman is the pinnacle of the DC Universe. Our feeling always was that you need to get Superman right. That was also our goal. We didn't want to ignore that this universe exists.

In films of terror, it's often not about being graphic. Or if there is a graphic image, it's extremely swift. Everyone talks about the shower scene in 'Psycho,' but that's the only graphic scene in the entire film.

I'd been a Superman fan since the time I was a little kid. We had great respect for the Donner movie, and Superman II with Terence Stamp as Zod but I felt it was time to bring the character into the 21st century.

Chicago's such a great city because it's got so many different brilliantly architecturally looking buildings, and you can really modify that city.

At least you used to know 'there's the villain, there's the good guy', but today there are more shades of grey.
