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.

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

I'm a huge fan of the Rod Serling sci-fi, where they could take the most odd and enormous ideas but ground them in something very human.

The big thing is it's a domestic drama. Everything else in science fiction tends to be high-concept. Really for the last 40 years or so I think sci-fi's been a little cold and a little inhuman quite often - certainly since the 1980s - and I really wanted to do something that almost felt like a regular, real-life drama but just set it in a sci-fi setting. I think the best stuff is always like that.

When that character and the X-Force appeared, they took the comic world by storm. You have to look at those numbers. And you see that that isn't Rob Liefeld's only creation. There's all these other things, like Cable and Domino. There's so many things that actually could be fascinating onscreen and unlike anything you've ever seen before onscreen. So I think Fox is in a really nice position where they've got something that feels as wide and different as the Marvel Universe.

Wanted has gone into second, third and fourth printings of the individual issues and the north American printings of Wanted #1 are now close to 100,000.

All my kids love superheroes, but my middle daughter in particular is obsessed with Wonder Woman and Batgirl.
