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.

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.

The truth is the music is really an incredible personal part of the movie. When I was drawing the storyboards for Watchmen, I had just gone to my iPod and was grabbing music. It took me about two weeks to really put my playlist together. But once I had it, I kinda just put my headsets on and drew for five months. But that music's the music that's in the movie.

Of course it would depend on the project, but I don't think I could ever separate myself from my aesthetic.

You can't have a Superman that is battling cultural morality. You need a Superman that has built in sort of values.

It's interesting now that basically a CG set is the same cost as a real set. So like if you're going to build a CG house in the suburbs, it costs you $200,000. And if you were going to build it in a computer, it'll cost you $200,000. It's the same... the relationship is exactly the same.
