Secret Agent is a 1936 British spy thriller film directed by Alfred Hitchcock, adapted from the play by Campbell Dixon, which in turn is loosely based on two stories in the 1927 collection Ashenden: Or the British Agent by W. Somerset Maugham. The film stars Madeleine Carroll, Peter Lorre, John Gielgud, and Robert Young. It also features uncredited appearances by Michael Redgrave, future star of Hitchcock's The Lady Vanishes (1938), Michel Saint-Denis as the Coachman, and Michael Rennie in his film debut.

Plot

On 10 May 1916, during World War I, British Captain and novelist Edgar Brodie returns home on leave, only to discover his obituary in the newspaper. He is brought to a man identifying himself only as "R", who asks him to undertake a secret mission: to identify and eliminate a German agent on his way to Arabia to stir up trouble in the Middle East. Upon agreeing, Brodie is given a new identity—Richard Ashenden—a fake death, and the assistance of a killer known variously as "the Hairless Mexican" and "the General", though he is neither bald, Mexican, nor a general.
