The document discusses the use of documentary films for propaganda purposes by different countries. It describes how countries like Great Britain, Germany, Russia, and Nazi Germany produced documentaries during times of war or political upheaval to promote their own viewpoint and portray the enemy in a negative light. Specific films mentioned include Triumph of the Will, Olympia, Nightmail, and films from John Grierson and Frank Capra's Why We Fight series. The document concludes by noting that propaganda is often only seen negatively when it belongs to an enemy view, while one's own nation's perspective tends to be viewed more sympathetically, and encourages the reader to detach from any national viewpoint.
