In the U.S., Superman or Batman or something, the law-enforcement people, are the most famous comic characters. Americans have a respect, I think, for badges and a respect for uniforms. I think that's, in some ways, quite a nice thing, but it can be dangerous, too, because it can obviously be abused.

The one thing we can all relate to is family, and family has its traumas sometimes. Sometimes things don't go well for people. Sometimes things are tough. So everybody kind of knows someone who's been in this situation before, and I think that's what makes it work.

One of the things that made Star Wars work was the kids didn't know who their dad was.

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."

I love the fact that they [girls ]are into Superman and Green Lantern and Batman and everything, and they really do have all those toys as well, but I don't want all their role models to be men.

What I wanted to do was drown something enormous, like a Star Trek or Star Wars kind of space opera-type thing, but actually make it about someone who was just married to the wrong guy, and that guy just happens to be this amazing dictator, and she has to get her kids as far away as possible from this guy. So something that could almost be a TV movie, if you'd ground it and set it in Wisconsin or something like that, but to give it this enormous setting.

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