It's been the most creatively liberating thing I've ever done and so I'm bringing some of that mad enthusiasm to Marvel for the next couple of years as they let me loose on some Marvel Universe titles you'll be hearing about soon.

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.

Being the first to do something like this also registers a lot of attention that the line might not have gotten if all four books had just appeared from one company.

However, if I can expand this to Top Cow or Avatar I'm helping the sales, however small, on my Marvel books because I'm almost certain to pick up some new readers.

Marvel books also feed into the smaller publishers and the fact that this is happening in the same month we're launching Ultimate Fantastic Four is no coincidence.

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

I'd love to do something else for Avatar after this.

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.

I spent as much time writing proposals in '98 and '99 as I did writing scripts.

I don't see one as bring better or more literate than the other and there's a real buzz to not only writing about a character I love like Superman, but also writing something that kids can enjoy.

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

Artists, no matter how good their intentions, are always slower than they think.

I didn't break into comics to write fairytales or crime comics.

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

The breadth of the potential readership is also a factor.
