The Trouble with Harry is a 1955 American Technicolor black comedy film directed by Alfred Hitchcock. The screenplay by John Michael Hayes was based on the 1950 novel by Jack Trevor Story. It starred Edmund Gwenn, John Forsythe, Mildred Natwick, Jerry Mathers and Shirley MacLaine in her film debut. The Trouble with Harry was released in the United States on September 30, 1955, then re-released in 1984 once the distribution rights had been acquired by Universal Pictures.

The action in The Trouble with Harry takes place during a sun-filled autumn in the Vermont countryside. The fall foliage and the beautiful scenery around the village, as well as Bernard Herrmann's light-filled score, all set an idyllic tone. The story is about how nine residents of a small Vermont village react when the dead body of a man named Harry is found on a hillside. The film is, however, not a murder mystery: it is a light comedy-drama with a touch of romance, in which the corpse serves as a MacGuffin. Four village residents end up working together to solve the problem of what to do with Harry. In the process, the younger two (an artist and a very young, twice-widowed woman) fall in love and become a couple, soon to be married. The older two residents (a captain and a spinster) also fall in love.

The film was one of Hitchcock's few true comedies (though most of his films had some element of tongue-in-cheek or macabre humor). The film also contained what was, for the time, frank dialogue. One example of this is when John Forsythe's character unabashedly tells MacLaine's character that he would like to paint a nude portrait of her. The statement was extremely explicit for the time.
