I am always nostalgic being in New York. Every neighborhood represents something to me. I lived here until I was 60 years old or so. So it was my life.

Ideally, anything one writes should have a social conscience: if you can write a story that thrills, and with a good message, that's the perfect type of a story.

The cliché I tried to avoid was I hated "teenage sidekicks." I always figured if I were a superhero, there's no way on God's earth that I'm gonna pal around with some teenager. So my publisher insisted I have a teenager in the series, because they always felt teenagers won't read the books unless there's a teenager in the story; which is nonsense.

I've written so many things over the years that I don't want to go back to being just a scriptwriter. I'm in what I consider to be the enviable position of all I have to do is come up with the idea and write an outline that makes it seem like it's a viable idea that will interest people, and then other people write the scripts -- and I become the executive producer or the producer, depending on how much involvement I have, and I get a creative credit and then move on to the next project.

If I were retired I wouldn't know what to do because I'd have to think, well, now what is it I want to do? And what I want to do is what I'm doing. I enjoy coming up with new ideas, which if I'm lucky they might be good ideas. I enjoy seeing them take shape. And I'm having fun doing it. So I wouldn't know why I'd want to retire.

I think people have always loved things that are bigger than life, things that are imaginative.

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.
