Life is never completely without its challenges.

I think it's just the challenge. It's not that all my life I've wanted to do characters [in Marvel] , because I never particularly thought about it, but the challenge of saying, "How could they be done differently that may be more absorbing or more effective?"

If you have a character that seems to be all perfect, it's hard to relate to him because when you read a story you really want to empathize with the character that you are reading about. And it's hard to empathize with someone who is flawless and who has no problems.

I don't expect every movie to be done exactly the way I would have done it.

If Shakespeare and Michelangelo were alive today, and if they decided to collaborate on a comic, Shakespeare would write the script and Michelangelo would draw it. How could anybody say that this wouldn't be as worthwhile an artform as anything on earth?

I've been very lucky. All I wanted was to pay the rent. Then these characters took off and suddenly there were Hulk coffee mugs and Iron Man lunchboxes and The Avengers sweatshirts everywhere. Money's okay, but what I really like is working.

I hate being too serious about anything. If I'm with my friend, I want to be having fun with him or her. And if anybody is reading my story, I want them to be not only reading the story, but I want them to feel they're having fun; that they're enjoying it. So any way you can make it more informal, more fun-filled, more amusing - instead of just a dry story that goes on and on - if there's any way to do that, I like to try and do it.
