On its original release the film was "slammed" by the German Embassy in Washington, USA and was censored within America as the USA's stance on Nazi Germany was yet still unclear.
It is also said that Vanderbilt had an audience with Adolf Hitler but this was not filmed, so the "re-enactment" of the meeting is added to the films stock. The authenticity of his "interview" cannot be verified.
Vanderbilt was an amateur film-maker visiting Berlin during 1933 who subsequently filmed the Nazi Rallies and the political rhetoric of the times.
Possibly the first American anti-Nazi film.
The film had been missing for almost seventy years and had been found (Circa 2013) stored away in Brussels.
