Watch the trailer for the upcoming documentary about posthumously acclaimed street photographer Vivian Maier.

The trailer for the upcoming documentary film about the posthumously acclaimed street photographer Vivian Maier was released a few days ago.

Finding Vivian Maier documents the discovery of more than 100,000 negatives photographed by the Chicago-based nanny Vivian Maier, who kept her street photographs secret for decades. The story itself is almost stranger than fiction, and the documentary should be an interesting look into the life of this mysterious photographer.
