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.

Who Honors those we love for the very life we live? Who sends monsters to kill us...and at the same time sings that we'll never die? Who teaches us what's real...and how to laugh at lies? Who decides why we live and what we'll die to defend? Who chains us...and who holds the key that can set us free? It's you. You have all the weapons you need. Now fight!

I write in a pretty straightforward way. I kind of sit down at page one and start writing.

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.

I think I just have a natural operatic aesthetic. I can't help it.

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.

The truth is these characters [of Batman story] evolve, and there's a lot of hands in the supporting of these characters. It's great when everybody can know where everything came from. It's important for the legacy of them.
