Some artists, such as Jack Kirby, need no plot at all. I mean I'll just say to Jack, "Let's let the next villain be Dr. Doom" ... or I may not even say that. He may tell me. And then he goes home and does it. He's so good at plots, I'm sure he's a thousand times better than I. He just makes up the plots for these stories. All I do is a little editing ... I may tell him that he's gone too far in one direction or another. Of course, occasionally I'll give him a plot, but we're practically both the writers on the things.

I used to be embarrassed because I was just a comic-book writer while other people were building bridges or going on to medical careers. And then I began to realize: entertainment is one of the most important things in people's lives. Without it they might go off the deep end. I feel that if you're able to entertain people, you're doing a good thing.

When you work with people whom you like and you admire because they're so good at what they do, it doesn't feel like work. It's like you're playing.

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.

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.

It's amazing what these superhero movies have become.

I don't wake up in the morning and say, wow I've got a great idea for a story. But I sit down, and I figure well, let's see.
