Actress Sarah Polley has made quite a career for herself as an actress in popular movies like the Dawn of The Dead reboot, and as a director with Away From Her and Take This Waltz. For the documentary film, she turns the camera on herself and her own family, and documents her own search for her real father. Using home movies, she builds up a picture of her mother and family life, then embarks on a series of interviews with her adoptive dad and the man she believes his her real father. Stories We Tell ruminates intelligently on the way people can lie to themselves about who we are, and Polley includes herself in this equation; she demonstrates how she has to fake elements of the story to deal with them. Where most documentaries happily take on the mantle of truth, Polley’s film looks with admirable honesty at the nature of lies and why we need them to survive.
