Michael Redgrave was also unknown to the cinema audience, but was a rising stage star at the time. He was reluctant to leave the stage to do the film, but was convinced by John Gielgud to do so. As it happened, the film, Redgrave's first leading role, made him an international star. However, according to Robert Osborne, host of Turner Classic Movies, Redgrave and Hitchcock did not get along; Redgrave wanted more rehearsals, while Hitchcock valued spontaneity more. The two never worked together again.
