Part of battle has been getting Hollywood to recognize that comic books and superheroes are not synonymous. That's been a huge breakthrough, just in recent years really, and as a result of that recent breakthrough, we've had movies like 300, Road to Perdition, and A History of Violence, that very few people realize were based on comic books and graphic novels. It's very important to make that differentiation.

If you look at all the comic book films that have come since then, in terms of tone, in terms of look, even in terms of Danny Elfman's music for Batman, so many that followed have been inspired by that, specifically. It had a cultural impact worldwide.

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.

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.

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 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.

I have great admiration and respect for the editors, writers, and artists of the comic books. They're turning out, I don't know, maybe 100 Batman stories a year, and the character turns 70 years old in May. It's incredible: for 70 years, on a weekly basis, every Wednesday, there is some Batman story coming out, if not a bunch of Batman stories coming out.
