We begin with Margaret Atwood, Bon Iver, home movies from the 1970s and we're totally in: Sarah Polley's very personal documentary about her mother, her family and a secret kept between them. "You know all about it, you know it's a delusion," narrates the man who raised her. "It's all done with mirrors, mate, they used to tell me...the mirrors in which you can see yourself clearly. The mirrors through which you can see what you really look like." What we see is an intimate portrait of an older generation of Canadian theatre vets, the children who live with their legacy and love's astonishing, multifaceted breadth. And then we get to examine the truth of all that's gone before in the reveal of how the story is told. Fascinating and unforgettable, this is confirmation (along with this summer's Take This Waltz) of Polley as one of the country's best cinematic storytellers.
