I just think adding superheroes to something instantly makes it more interesting. I have a friend who says every movie should either be a Spider-Man movie, or at least have Spider-Man in it. I thought it was such a brilliant quote. It kind of is true, in a weird way.

When you don't have time to do your job, that's a good indication you're playing the wrong game.

The breadth of the potential readership is also a factor.

I'm honestly as happy writing Superman Adventures as I am writing Wanted.

I always think it's a mistake when you actually have to set books aside and actually sit down and research something. I always think they've got to come from within.

We ordinary people might lack your great speed or your X-Ray vision, Superman, but never underestimate the power of the human mind. We carry the most dangerous weapon on Earth inside these thick skulls of ours.

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