Through the documentary, the audience will have an answer for the question: Who is Vivian Maier. She is one of the most excellent street photographers in the 20th century with taking over 100,000 great photographs during her lifetime.
But perhaps the most compelling mystery of all: Why-except for a meagre attempt at selling her landscapes for postcards in Europe-did she never 'push' her art into the world?
Why make a film about an unknown nanny from New York? The answer is because Vivian took photos that are as beautiful and powerful as those of any of the greatest photographers.
Through dogged research and interviews with the (now-grown) children Maier cared for, along with their parents (including Phil Donahue), a profile emerges, and it's fascinating.
