Night and Fog

How do the objectives of the films differ? 

In Triumaph of The Will, the objective was to show the German nation that Hitler could restore it's pride once again after WWII and the Versailles Treaty. At this time Germany had just lost WWI and lost much of it's wealth and power. Triumph of the Will tried to restore that pride in Germany by using Hitler as a sign of strength and tenacity.

In Night and Fog, the objective was to show the viewer how horrific the Nazi's truly were. This was the first documentary of the Holocaust so Night and Fog had to bring the public attention to the Nazi crimes and their methods of trying to wipe out entire races of people.
