The Spy in Black

The Spy in Black (US: U-boat 29) 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 a First World War spy thriller novel, The Spy in Black by Joseph Storer Clouston, into a film. Powell and Pressburger eventually made over 20 films during the course of their partnership. The Spy in Black stars Conrad Veidt, Valerie Hobson and Sebastian Shaw, with Marius Goring and Torin Thatcher as two German submarine officers. Grant Sutherland, a minister in Powell's The Edge of the World (1937), appears in this film as a Scottish air raid warden.
