Nora Prentiss is a film directed by Vincent Sherman, with a screenplay by N. Richard Nash, Paul Webster, and Jack Sobell. The cast includes Kent Smith, Ann Sheridan, Bruce Bennett, Robert Alda, and Rosemary DeCamp. Franz Waxman composed the music, and James Wong Howe was responsible for the cinematography. Dr. Richard Talbot (Smith) is dissatisfied with his ordinary family life. His existence takes a dramatic turn when nightclub singer Nora Prentiss (Sheridan) seeks him out for treatment of a minor injury – to her head, and seemingly, to his life. The film’s appeal lies in its fantastical premise, a hallmark of noir cinema. It's comparable to films like Dark Passage, where Bogart undergoes plastic surgery, or The Big Clock, which features Milland investigating himself. Like the unusual plot devices found in Kiss Me Deadly and City of Fear, or the identity-swap storyline of Hollow Triumph, Nora Prentiss offers a bizarre scenario that enhances the viewing experience. Though sometimes categorized as a woman’s melodrama, it's undeniably a clever noir film with an exceptional and improbable twist revealed toward the end. While there are elements of melodrama and romanticism, this is far from lighthearted entertainment; the resolution delivers a genuinely impactful emotional blow. Despite the title suggesting Nora Prentiss is central to the story, she isn’t the primary character; Doctor Talbot is. The title seems intended to boost Sheridan's career, as 1947 also saw her in The Unfaithful, again directed by Sherman. The plot doesn’t quite fit the conventional mold of film noir because Nora isn’t a femme fatale. Instead, the audience sympathizes with her; she’s not deliberately destroying Talbot’s life and is herself being manipulated by the doctor. Talbot demonstrates a lack of consideration for the impact his actions have on his wife and children, and he lacks courage to do what's right as he plans a new life with Nora. He then makes a decision—during an opportunity that arises in his medical office—that cleverly shifts the narrative into much darker territory. The film boasts high-quality technical aspects; there’s nothing wrong with Sherman’s direction, even if not all of his noir films are successful. He skillfully manages the tonal changes and elicits strong performances from the leads. The writers do a commendable job with Sheridan and Smith, providing them with complex characters entangled in a web of passion, unfulfillment, paranoia, and a significant lie. Waxman’s musical score is pleasing, and Sheridan even sings a few enjoyable songs. However, all these elements are overshadowed—as has happened to many others—by Wong Howe's photography. A master of low-key compositions, he combines expressionistic touches with visually tight, claustrophobic imagery. The scenes in the hotel room that Nora and Richard share, filmed in shadowy, clinical lighting after an operation, are particularly noteworthy, as is the symbolically rich scene where they talk through a prison grille. A box office success that helped revitalize Sheridan’s career, Nora Prentiss offers numerous reasons to watch it, especially for those who enjoy exploring the darker, sometimes eccentric corners of noir cinema. It earns a rating of 8/10.
