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.

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.

I think it's one thing if you are turning out dozens or even a hundred stories a year, you've got to have a great supporting cast behind you. Superman had a family that developed, and it's only natural that Batman has a family of sorts that developed. I think it's a great way to keep the comics interesting and varied, to appeal to different segments of an audience, to bring new perspectives to it.

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.

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.

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.
