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.

If I'm creating a new superhero, it shouldn't be any different from other superheroes in terms of the qualities. Obviously the personality can be different. I think traditionally in comics women have tended to be a girlfriend or the daughter of whoever, whether it's even Batgirl as Gordon's daughter, or whatever. There is that relation of the hero, you know, like Superman's cousin, Supergirl. And that's great. It's fantastic to have a link to these amazing characters, but I kind of like the idea of things being something in their own right, which is why I've always loved Wonder Woman.

I'm very lucky that I have this other career that runs alongside my comic career, which is a film career, and I've been given this really lovely setup where they seem to make the movies very quickly as well.

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

You kind of worry for the characters in a way that you don't normally in sci-fi, because sci-fi tends to be about the ideas, and this is about people.

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.

Maybe in this Star Wars world maybe subconsciously I was preparing myself. But I've just found all of my ideas I've been coming up with are big sci-fi things, and I wanted to do a big epic, a big space opera, and this is it. This is mine.
