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.

We can deny angels exist, convince ourselves they can't be real. But they show up anyway, at strange places and at strange times. They can speak through any character we can imagine. They'll shout through demons if they have to. Daring us, challenging us to fight.

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

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. But if you're looking at the philosophy correctly, and I never did - I like to think I did sometimes - you have to do it without ego, without the I. You have to separate yourself.

[Writing something original from scratch], the initial process is way different. But once it exists and you start to actually work on making it real, then the approach is kind of the same, for me anyways.

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.

I think that when you see the trailer [on movie "300"] - my feeling is anyway and maybe I'm not objective because I live it - but I think when you see it you immediately go, 'Okay, this is another sort of way of doing this.'
