Helene Bertha Amalie "Leni" Riefenstahl was a German filmmaker, photographer, and actress. She is considered one of the most controversial personalities in film history. Regarded by many critics as an "innovative filmmaker and creative aesthete", she is also criticized for her works in the service of propaganda during the Nazi era.
A talented swimmer and an artist, Riefenstahl became interested in dancing during her childhood, taking lessons and performing across all Europe. After seeing a promotional poster for the 1924 film Mountain of Destiny, she was inspired to move into acting and between 1925 and 1929 starred in five successful motion pictures. Riefenstahl became one of the few women in Germany to direct a film during the Weimar era when, in 1932, she decided to try directing with her own film, The Blue Light.
In the 1930s, she directed the Nazi propaganda films Triumph of the Will (1935) and Olympia (1938), resulting in worldwide attention and acclaim. The films are widely considered two of the most effective and technically innovative propaganda films ever made.
