One of the things I love most about oral history is how we can better understand our own identities through the power of other people's narratives. This concept becomes rather literal in Sarah Polley's Stories We Tell, a documentary that follows her colorful storytelling family through their memories, anecdotes, and tall tales. Contained in these stories is the possibility that the filmmaker was born from an extramarital affair and not the product of her familial father--a revelation that we as the audience apparently experience with Polley. I haven't seen this film so I can't say much about it except that the concept itself is worth a look. Anybody who creates anything knows how hard it can be to put yourself out there for the world to judge. Polley's self-exposure is multi-faceted and further complicated by a redefinition of her identity right on-screen...Well, that is to say, if there isn't some further narrative twist at the end and this extramarital affair turns out to be another one of her family's crazy tall tales. In any case, the movie will open on May 10 here in the US.
