Spione is a 1928 German silent espionage thriller directed by Fritz Lang and co-written with his wife, Thea von Harbou, who also wrote a novel of the same name, published a year later. The film was Lang's penultimate silent film and the first for his own production company; Fritz Lang-Film GmbH. As in Lang's Mabuse films, Dr. Mabuse: The Gambler (1922) and The Testament of Dr. Mabuse (1933), Rudolf Klein-Rogge plays a master criminal aiming for world domination.
