I think American audiences are quite interesting in that they can handle almost any amount of violence, but the moment the violence becomes sexual violence it immediately becomes an issue.

Likewise, I see no shame in writing Captain America or Wolverine.

The heart is a muscle, and you strengthen muscles by using them. The more I lead with my heart, the stronger it gets.

Would you rather see a super soldier battling Nazis or something more serious? Or lesbians down a coal mine? Generally, the films are engaging in the same way as the comics are. It's no coincidence that the biggest movies are genre-related, whether it's Lord of the Rings or comic books.

At the moment, I have it planned as a six or seven year experiment, but the books will only ever appear in bursts like this every couple of years and only with the best quality artists.

The books are all very, very different so the publishers really had to be different too.

I didn't want the headache of having a publisher reviewing everything I wrote in advance.
