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; he would play the male lead in Hitchcock's The Lady Vanishes two years later. This was also Michael Rennie's film debut (uncredited).
