Noir is dead for me because historically, I think it's a simple view. I've taken it as far as it can go. I think I've expanded on it a great deal, taken it further than any other American novelist.
Sometimes, the smaller roles in movies can be the most interesting. If you only take the stance that you'll only play central characters in movies, you'll find yourself not being able to indulge in that morally grey terrain that makes support characters so rich and interesting.
