If I'd written all the truth I knew for the past ten years about 600 people - including me - would be rotting in prison cells from Rio to Seattle today. Absolute truth is a very rare and dangerous commodity in the context of professional journalism.
That's what's nice about directing a film and having it done: There's nothing more I can do about it. It's done. That's it. All I can do is let it go and hope that people are kind to it.
