The Postman Always Rings Twice is a 1946 American film noir directed by Tay Garnett and starring Lana Turner, John Garfield, and Cecil Kellaway. It is based on the 1934 novel of the same name by James M. Cain. This adaptation of the novel also features Hume Cronyn, Leon Ames and Audrey Totter. The musical score was written by George Bassman and Erich Zeisl (the latter uncredited)..

This version was the third filming of The Postman Always Rings Twice, but the first under the novel's original title and the first in English. Previously, the novel had been filmed as Le Dernier Tournant (The Last Turning) in France in 1939 and as Ossessione (Obsession) in Italy in 1943.

Plot

Drifter Frank Chambers hitches a ride with District Attorney Kyle Sackett. Kyle drops Frank off at "Twin Oaks", a rural diner/service station on a highway in the hills outside Los Angeles. Frank begins working there. The diner is operated by the stodgy Nick Smith and his much younger wife, Cora.

Frank and Cora start to have an affair soon after meeting. Cora is tired of her situation, married to a man she does not love and working at a diner she wishes to own. While attempting to run away with Frank, Cora realizes that if she divorces Nick, she will end up with nothing. They return to Twin Oaks in time for her to retrieve the goodbye note she left in the cash register for Nick. Cora talks Frank into murdering Nick for them to have the diner. The plan involves Cora striking Nick with a sock full of ball-bearings and pretending he had fatally hit his head falling in the bathtub. Things go awry when a police officer stops by, and a cat causes a power outage. Cora eventually knocks Nick over the head and severely injures him.

It is determined that Nick will be all right, but no foul play is suspected, and he has no recollection of how he was struck. For a week, Frank and Cora happily run the business together. The officer stops by one day and tells Frank he passed Cora driving Nick back from the hospital. Frank sees no hope for a definite future with her and decides to move on before she returns. He goes to L.A. but after a couple of weeks, he starts hanging around the marketplace where Nick and Cora buy most of their produce, hoping to see her. He runs into Nick, who has been looking for him; Nick insists that Frank return to Twin Oaks with him, saying, "something important's gonna happen tonight, and you're in on it."

Upon Frank's return, Cora behaves coolly toward him; the three of them have dinner together, and Nick announces that he will be selling Twin Oaks and moving with Cora to care for his infirm sister in northern Canada. That night, Cora is desperate; Frank finds her in the kitchen with a knife she says she will use on herself. Frank agrees to kill Nick. The next day, the three of them are to drive to Santa Barbara to finalize the sale of Twin Oaks. Frank and Cora intend to stage a drunk driving crash. Sackett stops by to put air in his tire, and Frank and Cora stage an argument where she insists on driving because of the men's inebriation. On a deserted stretch of road, Frank kills Nick with a blow to the head and then sends the car off a cliff. However, Frank is also caught in the car and injured. Sackett, who followed them, arrives to find Cora crying for help.

The District Attorney files murder charges against only Cora, hoping to divide her and Frank. Although this ploy works temporarily, a measure by Cora's lawyer, Arthur Keats, prevents her full confession from coming into the hands of the prosecutor. Cora secures a plea bargain in which she pleads guilty to manslaughter and receives probation.

Publicity from the murder makes Twin Oaks successful, but things remain tense between Frank and Cora. They marry to protect themselves from being forced to testify against each other. When Cora leaves to care for her sick mother, Frank has a brief fling with a woman. After Cora returns, Kennedy, a man who worked as an investigator for her attorney, attempts to blackmail her with the confession. Frank beats up Kennedy and his partner, takes the signed confession from them, and burns it.

Cora tells Frank that she knows about his affair. The two argue but reconcile, and Cora announces that she is pregnant. She speculates that the new life they have created may balance the one they took. They go to the beach and swim, realizing they still love each other. On the way back, Frank accidentally crashes the car and Cora is killed.

Frank is tried and convicted for killing Cora. While on death row, he is visited by a priest and by Sackett, who confronts him with the evidence of his involvement in Nick's murder and reasons that if he resists his legal fate in Cora's death that he will only wind up back where he is with a conviction for Nick's murder. Frank accepts that, while he is innocent of Cora's death, his execution will be a fitting punishment for his murder of Nick.

Comparison to the novel While many scenes and pieces of dialogue in the film are nearly identical to Cain's 1934 novel, the 1946 film adaptation takes a number of significant departures from the book.

Some of these changes are attributable to requirements of the Production Code Administration (PCA). Producer Carey Wilson and his screenwriters sent different versions of the script back and forth with the PCA until the group ultimately endorsed it. Given that the final script sanitized some of the graphic violence and sex of the novel, the filmmakers take steps to make the characters’ actions more rational. This rationalizing project does not apply to Cora, however. In the film, Cora takes on the role of femme fatale, a popular archetype in the film noir genre.

From the first scene, it is clear that protagonist and narrator Frank Chambers serves a different role than he did in the novel. In this scene, a well-dressed Frank Chambers is getting a ride to the Twin Oaks Tavern from the district attorney. He is seeking gainful employment at the restaurant. In the novel, however, he is a drifter who makes his way to the Twin Oaks by sneaking onto a hay truck before being caught and kicked off. Instead of looking for a job, Frank enters the restaurant and cons the restaurant’s proprietor into giving him a free meal.

In the novel, the restaurant’s proprietor is Nick Papadakis, a man of Greek origin. Cain draws attention to his outsider status by writing Nick’s dialogue in fractured English. Frank often refers to him simply as "the Greek" and throughout the novel, this Greek ethnicity is a source of distress for Cora. In their first conversation, Frank questions why Cora has married a Greek person. Later on, Cora resents Nick for his "greasiness" and becomes upset at the prospect of having children with him for fear of their children being greasy.

The filmmakers omit this racist element of the plot, changing the character’s name from Nick Papadakis to Nick Smith. Instead of race being the motivating factor for Cora’s dissatisfaction with the marriage, Nick’s frugality and lack of likability become the driving forces in the film adaptation. The film makes Nick out to be a "cheap, penny-pinching, stupid, and unlikeable man." This is a serious departure from the novel where at Nick’s funeral, Frank cries and reflects on how much he liked Nick.

The film adaptation downplays the sexual nature of Frank and Cora’s relationship and essentially removes any notion of their sadomasochistic tendencies. In the novel, Cain gives a visceral account of Frank and Cora’s first romantic encounter in which Frank, at Cora's request, bites her lips to the point of blood dripping down her neck. One of their more graphic sexual run-ins occurs after Frank and Cora have murdered Nick. To make it look like they too have been injured in the car crash, Frank hits Cora in the face and rips open her blouse then proceeds to have sex with her. Later on in the novel, Cora asks Frank to rip open her shirt the way he did on the night that they murdered Nick.

In the film, their romantic encounters play out very differently. After the killing of Nick, Frank and Cora do not have sex. Instead, they clumsily attempt to push the car off the side of the cliff and Frank becomes inadvertently injured in the process. Additionally, when overt sexuality appears in the film, it leads to punishment. In one of the final scenes of the film adaptation, Frank crashes the car because he is distracted by Cora and her sexual allure. Essentially, Cora dies because of lust. In the novel, the car crash is far more random. Cora’s death does not occur as a direct result of sexuality.

The conclusion of the film is far different from that of the novel. The filmmakers attempt to give the story a happy ending. The love that Frank still has for Cora appears redemptive and he asks a priest to pray that he and Cora can be together after death. Frank appears to listen both to the priest and to the district attorney. In the novel, Frank is stoic in handling his imminent execution. He hopes that he can reunite with Cora after death but is less trusting of the priest.

Production In early February 1934, before Cain's novel was published, RKO executive Merian C. Cooper submitted a synopsis of his story to the Production Code Administration (PCA), which reviewed movie scripts using the Motion Picture Production Code (commonly known as the Hays Code). Upon reviewing the synopsis, with its themes of adultery and murder, the PCA persuaded RKO to abandon its plans to film Cain's story, calling it "definitely unsuitable for motion picture production."

After Cain's novel was released, Columbia Pictures and Warner Bros. expressed interest in the property, but Warner Bros. quickly rejected the story out of concerns that a film version would run afoul of censors. Metro-Goldwyn-Mayer purchased the rights to make a movie adaptation a full twelve years prior to the film's release. They paid Knopf $25,000. Cain received half that amount, and it is the only money he ever received from the movie and its successful remake.

MGM did not go forward with the project earlier as the Hays Code began to be rigorously enforced very shortly after they had acquired the rights. The studio finally decided to proceed in 1944, upon observing the success of Paramount's film adaptation of Cain's novella Double Indemnity, which violated many of the same moral taboos.

Lana Turner's character, Cora Smith, wore all white in every scene, except for three in which she wore all black: with the knife in the kitchen contemplating suicide, at the train station returning from her mother's death, and when she was calling the taxicab so she could leave Frank.

In 1936, Cain adapted his novel as a play, which had 72 performances at the Lyceum Theatre, in New York, from February to April 1936. The cast included Richard Barthelmess as Frank, Mary Philips as Cora, Joseph Greenwald as Nick and Dudley Clements as Sackett, with minor roles played by Joseph Cotten and Charles Halton.

Casting Lana Turner was cast as Cora Smith. Turner said this was a favorite role of hers. Cain felt that she was the perfect choice for Cora and was so impressed with her performance that he presented her with a leather-bound copy of the novel inscribed "For my dear Lana, thank you for giving a performance that was even finer than I expected." Bette Davis remarked "It's highway robbery that Miss Turner didn't get an Oscar nomination."
