Secret Agent (1936) is a British film directed by Alfred Hitchcock, loosely based on two stories in Ashenden: Or the British Agent by W. Somerset Maugham. The film starred John Gielgud, Peter Lorre, Madeleine Carroll, and Robert Young. Future star Michael Redgrave made a brief, uncredited appearance. Gielgud plays a British officer, a famous writer whose death is faked during World War I, and who is sent by the mysterious "R", head of British intelligence, to Switzerland on a secret mission. Carroll plays a female agent who poses as his wife. Lorre appears as a British agent working with them, a killer known variously as "the Hairless Mexican" and "the General". Typical Hitchcockian themes used here include mistaken identity and murder.
