The name of the film was Hitler's Reign of Terror. The year was 1933. The journalist behind the film was Cornelius Vanderbilt IV, a direct descendant of the railroad tycoon.
I loved this quote from Vanderbilt about Hitler:
Unquestionably he is a man of real ability, of force. But the way I sized him up after interviewing him is that he is a strange combination of Huey Long, Billy Sunday, and Al Capone.In retrospect, it is regrettable that he was a man of such ability and force.
If he had been less skilled,
there would have been fewer killed.
