Noir thriller, coming-of-age story, black comedy — Shadow of a Doubt, Hitchcock’s personal favorite among his films, is all these things. Directing Thornton Wilder’s (Our Town) script, Hitchcock crafts a masterly tale of a suave fugitive (Joseph Cotten) arriving in a small town to visit his sister’s family. “Young Charlie” (Teresa Wright) harbors a deep admiration for the man after whom she was named, but those feelings are tested as she begins to suspect that her beloved Uncle Charlie may be The Merry Widow Killer being sought by the police.
