Truth is stranger than fiction is a constant recurrence in our world, and it is always the theme of my favourite documentaries. Imagine a story where the hoarded belongings of a quiet, unassuming nanny are purchased at an auction, and that those items end up revealing one of the greatest photographers of all time. If that wasn't enough, then throw in conflicting back-stories of her origins, and a couple of rather dark twists and turns. All of which would never have been learned if the contents of a storage locker had been tossed away. Amazing, but true.

Finding Vivian Maier is compelling and fascinating stuff, we're screening it at the Mayfair tonight and Tuesday May 13 at 6:45pm.
