Leni Riefenstahl was a "fellow traveller" of the Nazi leadership but in the denazification trials that followed the Second World War she was never convicted. Later in life she won over 50 libel cases against people who stated that she collaborated with the Nazis. The documentary films she made most notably Triumph of the Will (1935) and Olympia (1938) are generally regarded as two of the finest documentary films ever made. There are film frames that can be taken from Triumph of the Will that are almost indistinguishable from the New York strret photographs of children by Helen Levitt. There are also troops viewed from above that are similar to photographs by Fritz Henle and Alexander Rodchenko. She used aerial photography to provide perspective and context.
