Answer
The answer is "Triumph of the Will". Leni Riefenstahl, a prominent filmmaker during the Nazi era, directed this propaganda film in 1935. "Triumph of the Will" presents a highly stylized and glorified portrayal of the Nazi Party rallies in Nuremberg, aiming to instill a sense of awe and loyalty towards the Nazi regime. It effectively served as a tool for Nazi propaganda, showcasing the power and unity of the movement.
