The Spy in Black is a 1939 British spy film, and the first collaboration between the British filmmakers Michael Powell and Emeric Pressburger. They were brought together by Alexander Korda to make the World War I spy thriller novel of the same title by Joseph Storer Clouston into a film. Powell and Pressburger eventually made over 20 films during the course of their partnership.
