Rudolf Klein-Rogge plays Dr. Mabuse, the criminal mastermind whose nefarious machinations provide the cover for — or describe the result of — the economic upheaval and social bacchanalia at the heart of Weimar-era Berlin. Initiated with the arch-villain’s diabolical manipulation of the stock-market, and passing through a series of dramatic events based around hypnotism, charlatanism, hallucinations, Chinese incantations, cold-blooded murder, opiate narcosis and cocaine anxiety, Lang’s film maintains an unrelenting power all the way to the final act… which culminates in the terrifying question: “WHERE IS MABUSE?!”
