This movie is currently in theaters and if you get the chance I highly recommend it. It is a facinating documentary about the nanny Vivian Maier who took tens of thousands of photos during her life but never showed them and they were not discovered until after her death when an individual purchased a box of negatives at an auction.
I had previously heard about Vivian Maier from new reports when her work was first discovered and I had recently watch the Art of Photography episode about her work https://www.youtube.com/watch?v=66oDaqgdTyI
The documentary is very thorough and tells a lot about Vivian through inteviews with her past employers and the children she used to nanny. I highly recommend it.
Have you seen the movie? What did you think?
