Pretty much all comic-book people, like all Hollywood people, for the most part, are pretty liberal. I think especially UK writers. Alan Moore is probably the most radical guy you'll ever meet. I grew up loving those guys, so my heroes, as a kid, were radical cartoonists, essentially. I couldn't help but - I grew up in a left-wing household. But I do think it's fun, writing right-wing characters. I've found it interesting, just as a writer, to get inside their heads and make them likeable.

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.

I've done so many superhero comics, and I've actually just been really excited about sci-fi, and Chrononauts and Starlight were both sci-fi, which I had a great time doing.

When I was a kid growing up in the '80s, the BBC showed those old Buster Crabbe serials like Flash Gordon and Buck Rogers. So instead of ponderous sci-fi or depressing sci-fi or dystopian sci-fi and all the things we're kind of used to, where it's always raining and it's always dark, I thought, "Wouldn't it be nice to do something that was just fun and absolutely nonstop?" Like, I love writing action, and this thing is that. It's all action.

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

Would you rather see a super soldier battling Nazis or something more serious? Or lesbians down a coal mine? Generally, the films are engaging in the same way as the comics are. It's no coincidence that the biggest movies are genre-related, whether it's Lord of the Rings or comic books.
