It's been a very interesting exercise as a writer - writing a little family group, like The Incredibles or The Simpsons or something like that, and setting it in a big Star Wars-type setting. It's been really fun, definitely different from the kind of thing I normally do.

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.

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

Anytime something becomes a success in this way you always get imitators. I'm an imitator of the guys I love. I imitate people like Frank Miller, who is a huge inspiration to me.

He [Stuart Immonen] and I have known each other over email for 18, 19 years or something, so to finally work with him is like kissing the girl that you always wanted to kiss.

I'm just running through this list of potential nannies and wondered if we should go for a superhero this time. Do you think Wolverine would be interested? He seems to be on every other team right now.

The lovely thing is, if Marvel had a Spider-Man movie over at Sony or something, they own the rights to the character, and the editors and producers make suggestions and get notes and things. But you're talking about Matthew Vaughn and Jane Goldman. They're two of the best people in the world. The notes are just things like, "This is absolutely brilliant."
