Shadow of a Doubt (1943 film) -- Directed by Alfred Hitchcock

Shadow of a Doubt is a 1943 American psychological thriller film directed by Alfred Hitchcock, and starring Teresa Wright and Joseph Cotten. Written by Thornton Wilder, Sally Benson, and Alma Reville, the film was nominated for an Academy Award for Best Story for Gordon McDonell. In 1991, the film was selected for preservation in the United States National Film Registry by the Library of Congress, being deemed "culturally, historically, or aesthetically significant". The film was also Alfred Hitchcock's favorite of all of his films.The project began when the head of David Selznick's story department, Margaret McDonell, told Hitchcock that her husband Gordon had an interesting idea for a novel that she thought would make a good movie. His idea, called "Uncle Charlie", was based on the true story of Earle Nelson, a serial killer of the late 1920s known as "the Gorilla Man".

Shadow of a Doubt was both filmed and set in Santa Rosa, California, which was portrayed as a paragon of a supposedly peaceful, small, pre-War American city. Since Thornton Wilder wrote the original script, the story is set in a small American town, a popular setting of Wilder's, but with an added Hitchcock touch to it. In Patrick McGilligan's biography of Hitchcock, he said the film was perhaps the most American film that Hitchcock had made up to that time.

The opening scenes take place in the East Ward (aka the "Ironbound"/"Down Neck" section of Newark, New Jersey). The city skyline and landmarks such as the Pulaski Skyway are featured in the opening shot. The location shots were used to comply with the wartime War Production Board restrictions of a maximum cost of $5,000 for set construction.

The Newton family home is located at 904 McDonald Avenue in Santa Rosa, which is still standing. The stone railway station in the film was built in 1904 for the Northwestern Pacific Railroad and is one of the few commercial buildings in central Santa Rosa to survive the earthquake of April 18, 1906. The station is currently a visitor center. The library was a Carnegie Library which was demolished in 1964 due to seismic concerns. Some of the buildings in the center of Santa Rosa that are seen in the film were damaged or destroyed by earthquakes in 1969; much of the area was cleared of debris and largely rebuilt.

The film was scored by Dimitri Tiomkin, his first collaboration with Hitchcock (the others being Strangers on a Train, I Confess and Dial M for Murder). In his score, Tiomkin quotes the Merry Widow Waltz of Franz Lehár, often in somewhat distorted forms, as a leitmotif for Uncle Charlie and his serial murders. During the opening credits, the waltz theme is heard along with a prolonged shot of couples dancing.
