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.

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 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.

The story of Kal-El is actually a great story about adoption. He is an alien who has embraced his human side. As much as he loves and honours his heritage, and he needed to know where he came from and discover who he was, he has to decide who he is going to be.

I was also an Action Comic fan when I was a young kid and those comic books affected me and Superman is - he's the one. He's the first one. He's the one. He's the one everybody is always compared to.
