At the end of 1932, Lang started filming "The Testament of Dr. Mabuse". Adolf Hitler came to power in January 1933, and by March 30, the new regime banned it as an incitement to public disorder. "Testament" is sometimes deemed an anti-Nazi film, as Lang had put phrases used by the Nazis into the mouth of the title character. A screening of the film was cancelled by Joseph Goebbels, and it was later banned by the Reich Ministry of Public Enlightenment and Propaganda. In banning the film, Goebbels stated that the film "showed that an extremely dedicated group of people are perfectly capable of overthrowing any state with violence", and that the film posed a threat to public health and safety.
