I regard sports first and foremost as entertainment so dry documentary narration is not for me.

On 'The Office ' so much of the show is about disguising your true feelings and your romantic feelings because it was a mock documentary.

I began to feel that the drama of the truth that is in the moment and in the past is richer and more interesting than the drama of Hollywood movies. So I began looking at documentary films.

Well it was actually - I brought the idea of doing a documentary to HBO back in 2000 when there were some press reports sort of were bandied about that there were going to TV movies based on some of the books that were out.

Doing a documentary is about discovering being open learning and following curiosity.

In feature films the director is God in documentary films God is the director.

We're telling a story. And the demands of that are different from the demands of a documentary. The audience must believe in order to keep faith in the story.

And in reality I don't think it's a real documentary. It's more a story of her life. It's a story of survival. It's a story of the time in which she lived. The story of success and failure.

The best films of any kind narrative or documentary provoke questions.

But one of the amazing things about documentary is that you can remake it every time you make one. There is no rule about how a documentary film has to be made.

I remember when I took Quentin Tarantino with me to a very private screening of the documentary 'Roman Polanski: Wanted and Desired ' which shows some of the legal irregularities of his case. I was involved by the film and it was an amazing experience to see people weep at the end of it.
