Since before the Neolithic revolution of 10,000 BC there have been stories. (I know this from reading in-depth about the Lascaux cave paintings and also from seeing 'The Croods.') While there was, is and always will be fiction, much of artistic expression has been used as a means to record what happened to us. 'Og Nearly Got Eaten by a Mastodon Today' – that would have been a big hit in the stone age.
Part of this process can be a search for an undeniable truth and part of it is self-discovery. That's at the heart of 'Stories We Tell,' a remarkable first-person documentary actor/director Sarah Polley made after she dug into some secrets about her own unorthodox upbringing.
