"Documentary films have also had a central importance in propaganda and politics. Leni Riefenstahl's notorious films on behalf of the German Nazi Party - particularly 1935's "Triumph of the Will" - have remained a startling reminder of the power of film as a medium to enthrall and influence a suggestive audience. Even modern documentaries are still often focused on community organizing, exposing social issues and rallying viewers behind a certain political attitude or opinion. Films like Michael Moore's "Fahrenheit 9/11" and the Al Gore-starring "Inconvenient Truth" are credited with influencing the American political discussion during the George W. Bush era, and in some cases, advocacy films have become intertwined with the causes they depict in the minds of Americans. Not surprisingly, a few of the documentaries listed here are also considered among the best movies of all time - documentary or otherwise."
