When you are dealing with approximately two-plus hours every few years to do a story, you don't have the luxury of having excessive screen time to explore, in detail and in-depth, lots of other subsidiary or ancillary supporting characters.

If you talk about genres - I don't care if you're talking about war, Westerns, science fiction, horror, fantasy, humor, romance - anything you can find, strolling the aisles of a Borders or a Barnes & Noble, I can bring you many comic books representing each genre.

There are times when you need to step back and realize that movie studios today are not necessarily the same things that they were many years ago. Many movie studios are international conglomerates now. They own everything from theme parks to toy companies to T-shirt companies to video companies. There's a lot of different wheels to be greased.

In a sense, comic books are frozen movies. If you look at a comic book, you are generally seeing the storyboard for a film. The great advantage of comic books, over the years, has been that, if they are frozen movies, they are not limited by budget. They are only limited by imagination.

I really became a hardcore Batman fan when I was eight years old. What was clear to me, the reason I liked him better than Superman or Spider-Man or the Hulk or whoever, was the fact that he was human, and I could identify with him, and I really believed in that character strongly. In my heart of hearts, when I was eight years old, I believed that if I studied real hard, and worked out real hard, and if my dad bought me a cool car, I could be this guy.

There's so much technology [in the Batman movies] that's unbelievable and seems unreal, so it's hard trying to get the audience to believe that it all exists. So we got Morgan Freeman to tell them that it's real. And that is why Christopher Nolan is a genius.
