Dr. Mabuse the Gambler / Dr. Mabuse, King of Crime is a two-part German silent film from 1922 directed by Fritz Lang. It was adapted by the novel of the same name by Norbert Jacques, which was written to deliberately mimic and cash in on the popularity of Fu Manchu and Fantomas while delivering political commentary about Weimar Germany. It follows psychoanalyst and criminal mastermind Doctor Mabuse, who has gained wealth and control of Berlin through a vast and elaborate crime network that he uses for everything from counterfeiting and sabotage to manipulating the stock market through complex means. Eventually, Chief Inspector Norbert von Wenk begins to unravel the complex defenses surrounding Mabuse's identity and becomes determined to take him down.
