El triunfo de la voluntad
Despite the emigration of many film-makers and the political restrictions, the period was not without technical and aesthetic innovations, the introduction of Agfacolor film production being a notable example. Technical and aesthetic achievement could also be turned to the specific ends of the Nazi state, most spectacularly in the work of Leni Riefenstahl. Riefenstahl's "Triumph of the Will" (1935), documenting the 1934 Nuremberg Rally, and "Olympia" (1938), documenting the 1936 Summer Olympics, pioneered techniques of camera movement and editing that have influenced many later films. Both films, particularly "Triumph of the Will", remain highly controversial, as their aesthetic merit is inseparable from their propagandising of Nazi ideals.
