The Hitler Gang
The Hitler Gang is a 1944 American pseudodocumentary film which traces Adolf Hitlers political rise, purportedly based only on documentary fact. The filmmakers chose to avoid casting stars in the lead roles, assembling instead a remarkable company of lookalikes to play Hitler, Goebbels, Hess and other leading Nazis.
Buddy De Sylva says he got the idea to make the movie after seeing the German propaganda film Ohm Paul Kruger and he had the idea of making a movie about Germany only telling the truth.
