Even in our business, as is the world, we are in the age of specialisation. You see a lot of names of producers on a movie. If you have the idea, if you oversee the development, if you oversee the production, if you help package the movie, you sell the movie - you can be a producer. There's not a lot of us who do the whole gamut.

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 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.

It's rare that I'm working on a movie and that's the case. My goal is the same, ultimately at a certain point you give it to the director and their vision. You're there to support that vision.

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.

There is an expectation with a superhero film that there is spectacle and action but there also has to be heart. Striking that balance is really important.

People tend to think about God more when the clock starts to wind down.
