It was interesting to shoot history as it happens, without anyone demanding a huge story.

To make theater out of real life, you need to catch dialogue when it happens.

Somebody like Bowie was so interesting because when you got him off stage, he was like a businessman. But on stage, he was just dazzling. It was like watching butterflies grow.

Theater is where you go to find out something new that you don't know. It goes through somebody's brain and comes out in a comprehensible way that is beautiful, that's really interesting.

Before the camera, you only had secondhand takes - someone had to tell you what they saw or draw a picture of it or sing a song. Because of the camera, sometimes to our horror, we now know everything that happens in the world - things that before we were sheltered from.

When you're editing, you're putting it together in a way that makes sense metaphysically. You're not inventing it, but you're finding the story that's there. You're making a play that's eventually going to go on stage and present itself to an audience. You want to show what happened, not exactly what you have evidence of happening.
