Secret Agent is a 1936 British espionage 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.

Thriller film, also known as suspense film or suspense thriller, is a broad film genre that evokes excitement and suspense in the audience. The suspense element found in most films' plots is particularly exploited by the filmmaker in this genre. Tension is created by delaying what the audience sees as inevitable, and is built through situations that are menacing or where escape seems impossible.
A common theme in thrillers involves innocent victims dealing with deranged adversaries, as seen in Hitchcock's film Rebecca (1940), where Mrs. Danvers tries to persuade Mrs. De Winter to leap to her death.
