The difference between 'Watchmen' and a normal comic book is this: With 'Batman's Gotham City,' you are transported to another world where that superhero makes sense; 'Watchmen' comes at it in a different way, it almost superimposes its heroes on your world, which then changes how you view your world through its prism.

There's very few dork movies made by dorks.

Well, Bradbury's a genius. Fahrenheit 451 is one of my favorite books of all time, and The Illustrated Man as a collection of short stories ranks up there. When you read it you realize how influential it is on so many other stories and people.

don't mean to sound weird but I get so immersed in the source material when I'm working on a movie that I kind of lose the line between what I thought of and what was in the book.

The cool thing about Watchmen is it has this really complicated question that it asks, which is: who polices the police or who governs the government? Who does God pray to? Those are pretty deep questions but also pretty fun questions. Kind of exciting. It tries to subvert the superhero genre by giving you these big questions, moral questions. Why do you think you're on a fun ride? Suddenly you're like how am I supposed to feel about that?

The challenge with 'Watchmen' is making sure that the ideas that were in the book got into the movie. That was my biggest stretch. I wanted people to watch the movie and get it. It's one of those things where, over time, it has happened more.

I imagine the film ["300"] as if I was a Spartan and I had never seen an immortal or a Persian, or an elephant or a rhino for that matter.
