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 always, always got to be the last man standing.

If I know what something's about, and I can always have that touchstone, I feel like I can reach for really ridiculous humor and also go really dark in terms of the things I'm afraid of.

"The Cursed Wheel" is the heart of the whole year on All-Star. All-Star is a series that's largely compartmentalized so that every artist can reinvent a villain and have Batman go up against the villain in a way that's pretty singular.

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

First of all, what made him [Duke in "Zero Year"] captivating is this sense of somebody who wants to save the city regardless of whether Batman wants to or not, but has been inspired by Batman. He's always been - not combative with Batman or anything - but I think he has a sense that what Robin is and what heroism is in Gotham is something that's inspired by Batman and sort of separate from Batman.

I think thing that makes Batman so endlessly interesting is that he's one of the most flawed and deeply human characters, even though he seems completely the most inhuman and infallible in costume. Psychologically he's one of the most complicated in both his strengths and his weaknesses. For me, one of his great strengths and weaknesses is that confidence. His emotional self-protection is one of the things that makes him heroic and sacrificing; he doesn't have a personal life. He sacrifices those to be the best hero he can be.
