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 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.

What Batman is saying is that, "I want to try something new that's more about this era and this moment." And I do think that it speaks to a modern take [as opposed] to a 90s take or a 2000s take being maybe the older program about having a sidekick.

One of the things that's great is that Batman is a character that lends himself to very personal stories.

I love The End of the Batman story. I have my original copy, the hardcover, at my house from when I was a kid, whenever that was,'88 or '89. It was very influential to me because it was so explicit in touching on the notion that Batman might be mad and that he might belong in the mad house.
