Particularly, the actors, to have analyzed the script in great detail from the point of view of their specific character. So that they have a handle on exactly where the character is in the chronology of things. In that sense the actors become your best check on the logic of the piece, and the way in which it all fits together. They become essential collaborators. The main thing is you have to work with very smart actors.

When I look at a digitally acquired and projected image, it looks inferior against an original negative anamorphic print or an IMAX one.

What drew me to Batman in the first place was Bruce Wayne's story, and that he's a real character whose story begins in childhood. He's not a fully formed character like James Bond, so what we're doing is following the journey of this guy from a child who goes through this horrible experience of becoming this extraordinary character. That, for me, became a three-part story. And obviously the third part becomes the ending of the guy's story.

Film is the best way to capture an image and project that image. It just is, hands down.

I'm taking a bit of a wait-and-see attitude towards 3D.

I have always been a huge fan of Ridley Scott and certainly when I was a kid. 'Alien,' 'Blade Runner' just blew me away because they created these extraordinary worlds that were just completely immersive. I was also an enormous Stanley Kubrick fan for similar reasons.

A hero can be anyone. Even a man doing something as simple and reassuring as putting a coat around a young boy's shoulders to let him know that the world hadn't ended.
