There have been so many interpretations of both Batman and the Joker in the comic books themselves over the decades, from one extreme to the next, and in the media, from one extreme to the next.

They [comic books] are not a genre, they are not something to get hot and cold from one year to the next, they're the exact same thing as books and plays: they are a source of great stories and colorful characters.

I think every filmmaker makes different choices. I remember in the early days, in some of the early comic book movies, certain white dissolves were used that would try to emulate the look and feel of comic book panel borders. Sometimes they would frame shots in panels or circles that gave it a real comic book feel.

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 reject the concept that comic books in movies are a genre. I have been fighting that for many years, with the powers-that-be in Hollywood.

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.
