The most rewarding part for me though, was how Polley documented herself creating the documentary. You get a real behind-the-scenes view into what makes a video biography happen. And I saw myself a bit in Polley as she interviewed her subjects too. But because these people were in her immediate family, it must’ve been more difficult than ever to keep her mouth shut as people told stories she could add to, or debate. She sat there with her mouth closed, because as the director this was not her story.
