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.

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.

Marvel movies, are seeming slightly less exciting now that Star Wars has appeared and everything.

The heart is a muscle, and you strengthen muscles by using them. The more I lead with my heart, the stronger it gets.

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

I just trust the people involved. Marvel and DC for the last 16 years - is that 90 percent of the time it's incredible top talent. Like, this is what makes it different from the pre-2000 superhero movies. I would say, except Tim Burton and Richard Donner, it was generally, comic book movies were done by guys who weren't that into the material and people who didn't really respect the stuff. But as everything, whether it's Wolverine, X-Men, Avengers, Batman, all these things, it's just been done by top-tier people. I have total confidence that they'll continue that tradition of being great.
