Berlin, 1938: The premiere of "Olympia", a powerful documentary by Leni Riefenstahl, about 1936 Summer Olympics in Berlin. The film is Riefenstahl's masterpiece, a great symphony of kinetic sport beauty, but the fact that Riefenstahl was commissioned by the Nazis to make this film to praise the Third Reich, and that she was Hitler's "Lieblingsregisseurin" (favorite director), made this film controversial.
