I think up to this point, it's been difficult to suggest a world where Batman and Superman and Wonder Woman and others could exist in the same universe. That was one of the things I really wanted to try and get at. Not to mention, the amazing opportunity to bring those characters and have those characters tell an important story, their own story, within the confines of a film.

I think that, for me, Superman just seemed to make a lot of sense to me. After doing 'Watchmen,' it was - you know that thing, you've got to know the rules before you can break them? There was something about that in making 'Watchmen.'

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.

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.

It's difficult to find a movie that feels true to itself. You feel the hand of Hollywood, the moviemaking by committee, on everything.

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.

Also I've got to say in the movie ["300"] Gorgo, who is the Queen, she has also a part that is - I think - I don't want to say, 'Oh look, it's multi-quadrant,' and all this. I believe that it is because I think my dad can see this movie and go, 'F**k yeah!
