Film show: A poignant tale in 'The Most Precious of Cargoes'

French director Michel Hazanavicius decided that an animated feature was the best approach for his latest film, which follows the trajectory of a baby thrown from a train headed for Auschwitz. Film critic Emma Jones tells us why the fairy-tale tone of "The Most Precious of Cargoes" adds to its poignancy, and why this fable is worth telling many decades later. We also discover an up-and-coming talent in French filmmaker Agathe Riedinger, as her Cannes début "Wild Diamond" impresses with its timely subject matter and specifically female insight. Plus we learn more about musician Pharrell Williams, as his life is rendered in Lego form in the documentary "Piece by Piece", while Afghan women tell their own story in "Bread and Roses", a courageous account of life under the Taliban.
