We live in a much more complicated time than when Superman was created 75 years ago. Or even when Superman The Movie was created in the 70s. There are great advances but with those come a great many complications.We felt that the character needed to grow up in that kind of environment and had to face those kinds of colossal choices that were not going to be easy. It's difficult to figure out the right path. And even if you do good there are causalities to your choices. We thought it would be compelling.

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.

For a long time, the film business was a single-digit business on investment return. Now, because of home video, it's a low double-digit business, and the studios want to make sure it doesn't go back into the single-digit business.

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.

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.

You think that it must be great to be Superman but it's also hard to be Superman, especially when growing up.
