The thing with Superman is that he's completely emotionally open to the reader. Meaning what he tells you is what he's feeling; there's a transparency there. And what he tells other characters is usually as transparent as can be. What he says he believes in. So there's an honesty that is both really inspiring writing the character. One thing I love about Clark Kent is that there is a badassery that you don't see a lot. Even as Superman, he's always kind of restraining himself. When you challenge him, I think there's nobody that has a stronger spine than Superman.

I spoke to Geoff Johns a lot. We went back and forth, and found a way to bring up the best qualities in his personality and psychology and also fill a niche in Gotham that we've never seen. It became about is there a way to really plant this hero in Gotham and say this is someone you haven't seen before - both in terms of who they are as a person and who they are as a hero.

On this global stage, Superman is someone that we can all look up to and he's almost kind of ultimately American.

You take the thing that is the worst thing that could have happened to you, the worst challenge in your life, and you turn it into fuel. You don't give up. And that's what Gotham is about.

Having that North Star for every story [about Batman] is really key for me. It allows me to go farther and farther off the reservation.

I really wanted to make sure that if we set Duke up, that he's set up the right way and he's his own hero for the right reasons.
