Triumph of the Will’s effectiveness lies in its ability to convey emotions, rather than just listing facts and statements. This is the significance of having the propaganda film made by an artist and not a member of the party - artists know how the most minute details can make the audience unconsciously internalize the message of the piece. This is also the reason why Leni Riefenstahl is responsible for the impact of the film.
It is true that Riefenstahl did not orchestrate or verbally express sympathy with the events she recorded, but her choices of camera, angle, lighting, and transitions affirm the Nazi ideology. Many shots of Hitler have the camera below him, facing up, establishing his god-like role. Furthermore, as expressed by Riefenstahl herself in The Wonderful Horrible Life of Leni Riefenstahl, she used a telephoto lens in some crowd scenes to make them seem more densely-packed. The impact of that artistic choice is that it exaggerates the power and support the party has, threatening those who are not part of the group. Additionally, in one of the early scenes of Hitler’s arrival, the filmmaker uses specific lighting conditions to lighten his hair, to align it more with the Aryan ideal. In fact, the filmmaker captures the Aryan ideal in many scenes by cutting to images of blonde women, children, and workers, to establish who Hitler is speaking to when he addresses the crowds in a positive manner. When Hitler tells the crowd that they are the blood of Germany, the future of Germany, the hope for Germany, the filmmaker lets the audience know that he is speaking to a very limited group of people, even more specific than the crowd that was actually present. By doing this, she contributes to the idea of racial purity in a subtle way. After viewing the film, a light-skinned blonde person would feel empowered, knowing their leader cares about them. Those who don't fit this stereotype walk away knowing that when Hitler imagines an ideal future, they are not in it.
Leni Riefenstahl did more than simply complete a commissioned film, because she made certain artistic decisions that she was not directly told to make. It is very unlikely that a Nazi official told her which lens or angle to use, so the Nazi ideology conveyed through those artistic decisions are her responsibility. As stated in The Mass Psychology of Fascist Cinema, “she created, rather than merely documented, an event.” The filmmaker could have documented the events surrounding the Nuremberg rally, but instead she specifically and subtly glorified the crowds, the blondeness, the leader, and the value of order and obedience.
The damage caused by the film was not only in what it showed, but also what it didn’t. The film portrays an exclusively positive Nazi event, excluding the daily antisemitism, the physical abuse faced by boys in the Hitler Youth, and the other horrific components of Nazi Germany. The victims of the Nazis are not in the film, giving off the impression that they were so unimportant, they didn’t even need to be mentioned. This also made the viewer of the film much more comfortable. For people considered Aryan in 1930s Germany, watching the film would be like a vacation for their brain. The gorgeous scenery and music, the smiling faces of the crowds, and the optimistic words of the chancellor, gave them pride in their nation, without the guilt of thinking about those who were excluded from the idea of a perfect Germany. Germans who were not yet 100% supporting the Nazis were lulled into the collective dream of an exclusionary utopia. Additionally, Leni Riefenstahl specifically edited out moments that made Hitler human, such as rubbing his nose, coughing, or making a statement that didn’t generate huge applause. This gave all viewers the impression that he was not only above flaws, but above humanity. When a leader is portrayed this way, people who already supported him are then less likely to question his statements or actions, and those who didn’t support him were made to think that they were up against a godly force.
