This is one of the last of the great expressionist claasics from UFA, made right before the Nazis took over Germany and made freedom of expression a thing of the past. Dr. Mabuse, played by the astounding Rudolf-Klein Rogge, embarks on a campaign of crime that is designed to do nothing more than to cause the breakdown of society and to spread chaos -- Mabuse's underlings spout actual Nazi propaganda, so what exactly is being attacked here is quite obvious. The cinematography is stunning and the acting is superb, but the use of voice I find rather decreases the visual impact of the expressionistic genre. After this film was made, Lang, the director, was forced to flee for his life as the Nazis imposed total control over Germany and UFA became a propaganda tool. The subplot of a decent man forced into a life of crime by poverty may also be of interest of thos who might wonder how a man like Hitler could have gained so much power in the first place.
