Sundance Selects will release John Maloof and Charlie Siskel’s feature documentary FINDING VIVIAN MAIER, which will have its world premiere in the Documentary section at the 2013 Toronto International Film Festival.

FINDING VIVIAN MAIER unearths the untold story of one of the greatest photographers of the 20th Century, who was a mystery to even those who knew her. A nanny in the wealthy North Shore suburbs of Chicago, Maier’s secret world is unraveled slowly through her photo collections and interviews with those who knew her — parents who hired her, children she cared for, store owners, movie theater operators, and curious neighbors who remember her. The story that emerges goes beyond clichés of the undiscovered artist to offer a portrait of a woman who left a legacy of transformative work.
