There’s no doubt: Shadow of a Doubt (1943) was director Alfred Hitchcock’s favorite of his own films. I was surprised to learn this; I would have assumed it was North by Northwest (1959) because Cary Grant was his favorite actor to work with. But Hitchcock confirmed that Shadow of a Doubt was his favorite in an interview with talk show host Dick Cavett in 1972. But why was this film Hitchcock’s favorite? Hitchcock’s daughter, Pat, said, “this was my father’s favorite movie because he loved the thought of bringing menace into a small town” in the documentary Beyond Doubt: The Making of Hitchcock’s Favorite Film (2000). The film also held sentimental value for Hitchcock, as he injected many personal touches and also enlisted the help of his wife to write the screenplay.
