Having defined the espionage genre with Dr. Mabuse, the Gambler, Fritz Lang returned to the genre with this surprisingly fast-paced and remarkably grim thriller. Rudolf Kleine-Rogge stars as Haghi, the head of an elaborate criminal empire, and Willy Fritsch is the undercover agent assigned to topple the diabolical king from his throne. Filled with the sexual intrigue and high-tech gadgetry that continue to define the genre, Spies remains remarkably contemporary, more than 85 years after its original release.
