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.

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.

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

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.

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.

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.

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.
