Stolen Life (1939)

Adapted from the best-selling novel by K. J. Benes, A Stolen Life serves as a tour de force for German actress Elizabeth Bergner, whose husband Paul Czinner directed the film. Bergner stars as identical twins Sylvina and Martina, whose mild sibling rivalry intensifies when one of the girls tricks the other's sweetheart Alan McKenzie (Michael Redgrave) into proposing to the wrong twin.
