In the Making Of book ["300"] there's a guy named Victor Davis Hanson who is a a frickin genius. He's a Greek historian and we showed him the movie because I wanted him to write a forward to the Making Of book. I was a little nervous to be honest, because I wasn't sure how he'd react.

I understand the rules of Superman - not necessarily better than anyone else - but better than a normal filmmaker would. After doing 'Watchmen' and digging that deep into the why of superheroes, when Superman is presented to you, I felt like I was in a unique position to say 'I get this guy. I know what this is.

You can't teach anyone. You can't tell anyone. That's the thing you have to sit down and experience in order for it to mean anything. You can't intellectualize it. It's like why movies are cool. It's a combination of pictures and design and acting and music can create an experience that is outside of the experience that you can actually have in reality, which gets to my motion picture philosophy. People are like, 'aren't you trying to make the movies as real as you can?'

There was this interesting quote: try and live your life without fear and desire. It's this concept that's like when you look at a painting in a museum and you are held in aesthetic arrest. So the I, the ego, is stripped, is gone. The observer and thing become one. That's where fear and desire come in because you don't want to own it, possess it, desire it, and it's not moving you to fear. It's like you're in this harmonious state with the object.

I'd say the purest experience for the movie is not to have read the book because I think when you've read the book you're just ticking off boxes. I think that after you see the movie, reading the book is a cool thing. I always say the movie's not meant to replace the book. That's ridiculous. I'm a huge fan of the book.

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.

One of the things I think is important about 'Watchmen' is that it have resonance within cinematic pop culture as well as superhero culture.
