Fritz Lang takes his greatest villain and the detective from one of his master works and combines them into a critique of the current administration to make The Testament of Dr. Mabuse (1933). Despite party members trying to shut it down. Lang had maintained that M was not an anti-Nazi film. The Testament of Dr, Mabuse is inarguably one. Still Goebbels is said to have insisted that Nazi Germany's films should be like those of Fritz Lang, though not actually the works of Fritz Lang, as he was banned from making films in Germany after this one.
