Leni Riefenstahl, who died in 2003, will always be remembered for her film of the 1936 Olympic Games in Berlin. After the war, Riefenstahl was shunned by the film industry both in Europe and America, despite a 1952 court ruling proclaiming her not guilty of supporting the Nazis in a punishable way. Winner of the Boardman Tasker Award, this is a fine and balanced study of a still-controversial figure.
