I never tried to write for other people. I liked people who had problems I might have, because we all have insecurities, regrets. I like heroes who were not 100-percent perfect, who things to take care of.

I'm just somebody who tries to write things that entertain people. And if I can do it in a way that makes them prefer to emulate the good guy than the bad guy, I'm happy.

One of the keys is, and it may sound funny, talking about characters with super powers, but one of the keys is to make your characters as realistic and believable as possible. Even if they have super powers, you say to yourself, "Well, if somebody had a super power like this, what would his life be like? Wouldn't he still maybe have to go to the dentist or wouldn't he have to worry about making a living? What about his love life?" You've got to make characters that your reader can believe exists or might exist.

A superhero's catchphrase should be like a really memorable advertising slogan. It sticks in your head and you can't stop humming it. And let's face it, superheroes are just really selling themselves as products.

The comics of course, help the movies, because all of the comic fans want to see the movies. And the most amazing thing about it is these movies seem to appeal to young people, to old people, and to people all over the world. They're as popular in China and Latin America as they are here. That's really amazing and gratifying.

To be honest, when I was writing these stories a million years ago, I never thought about movies at all one way or another. It would have seemed almost miraculous for these things to be movies someday. To me, they were just comic books that I hoped would sell so I could keep my job.

Just because you have superpowers, that doesn't mean your love life would be perfect. I don't think superpowers automatically means there won't be any personality problems, family problems or even money problems. I just tried to write characters who are human beings who also have superpowers.
