The thing about 'Dark Knight' is its objective is to set Batman into your world, so that you can imagine the moral dilemmas he faces are exactly parallel to moral dilemmas that you would face in this world, today, if you were out there fighting crime dressed like a bat.

You can't will something into being. If you follow that philosophy all the way, to will something into being, that's animal style. That's what man does.

When I make a live-action movie, it's a very physical process. It's like running a marathon.

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.

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

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.
