When you can sit down with a plain sheet of paper in front of you and make some notes, and, little by little, you see it take shape and become a concept for a movie or a TV show. That's a real thrill. You watch it go from notes on a paper to a meeting with writers and directors and actors. I can't think of anything that's more exciting.

Comic books themselves are getting more literate. And there are people who are screenwriters and television writers and novelists who are writing for the comics, for some reason, they love doing it and some of the art work in the comics, I mean it rivals anything you'll see hanging on the walls of museums, they're illustrations more than drawings and all the people are discovering this and they're turning on to it.

To me everything is fun. I've started Twittering or tweeting recently and that's been fun.

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.

To my way of thinking, whether it's a superhero movie or a romance or a comedy or whatever, the most important thing is you've got to care about the characters. You've got to understand the characters and you've got to be interested. If the characters are interesting, you're half-way home.

I love all the voiceovers I do. I can't remember them all, but I seem to do them all of the time. And there's nothing easier because you just stand and read the script, and you don't have to act the way actors do. You don't have to be made up and put costumes on.

People like stories that are bigger than life, about characters with unusual powers. And when you get all the characters in the zodiac, it's so colorful, and it's so rich in different attitudes that the characters have.
