Plot
Constance "Connie" and Edward Sumner have a generally happy marriage together and live in upscale Westchester County, New York with their eight year old son, Charlie.
While shopping in SoHo, the wind knocks Connie into a young, handsome Frenchman named Paul Martel and they fall over. Paul then invites Connie into his apartment, where he cleans and ices her knee and then places his hand on hers. Paul insists that Connie takes a book before she leaves, addressing a passage about seizing the moment. When Connie returns home and opens the book, she discovers Paul's phone number inside of it.
Connie later calls Paul and he invites her back to his home; they flirt again and on her third visit, they dance and have sex.
Soon, Connie keeps on finding excuses to continue seeing Paul and Edward becomes suspicious when he notices her satin lingerie and catches her in a lie. Later on, Edward fires an employee for perceived disloyalty, and the employee, who witnessed Connie and Paul kissing in a diner, tells him to look at his own family. This inspires Edward to hire a private investigator to spy on Connie and he's devastated to see photos confirming her adultery.
One day, Connie forgets to collect Charlie from school, realises her wrongdoing and attempts to call Paul to end their affair. With the phone call being unanswered, she tries leaving him a voicemail but is interrupted by Charlie. She then drives to Paul's home to end their affair in person, but instead spots him with another woman. After attacking Paul in a library, she angrily confronts and questions him about how many other women he's seeing. Paul claims the other woman is just a friend and nothing more, but Connie doesn't buy it and tells him that their affair is officially over. She then storms out of Paul's apartment, but he catches up with her and forces himself upon her. Eventually, Connie succumbs to Paul and they have makeup sex in the hallway.
Afterwards, Edward arrives, narrowly missing Connie who was just leaving. Paul lets Edward into his apartment, and while the pair talk about Connie, Edward discovers Paul's messy bedsheets and a snow globe that he gifted her on his shelf. Overcome with rage, he brutally hits Paul twice over his head with it, fracturing his skull and killing him. While Edward cleans up the evidence, he overhears Connie's tearful voicemail ending her affair with Paul, erases it, and puts the body in the trunk of his car before dumping it in a landfill.
The next day, New York Police Department detectives find Connie's number in Paul's home and visit the Sumners after his estranged wife has reported him missing. Connie is surprised to learn that Paul was married but falsely claims that she barely knew him. The NYPD return when they found his body and question Connie again, and after they leave, she breaks down crying.
At the dry cleaner, Connie discovers the photos of her and Paul in Edward's laundry, and at a party that night, she discovers her snow globe back in their collection. When she confronts Edward, he responds by telling her that he knew about her infidelity from day one and then breaks down while telling her how hard he worked to give her and Charlie a better life, accuses her of being ungrateful and throwing away a hardworking husband and a happy family for an affair, before telling her that he hates her and that he wanted to kill her instead of Paul.
Days later, Connie discovers a hidden compartment in the snow globe, where years prior, Edward placed a photograph of them and an infant Charlie, with a message reading: ″To My Beautiful Wife, The Best Part Of Every Day!″. Realising how much he loved her, she burns the incriminating photos of her and Paul. Edward says that he will turn himself in, but Connie objects and they return to a normal life together.
Returning home one evening, Edward stops at a red traffic light. Connie falls into an escape fantasy that they could leave the country to adopt new identities, as Edward agrees. While he consoles her as she cries, it is shown that they have parked near a police station.
Cast
Production Development According to actor Richard Gere, an early draft of the screenplay presented the Sumners as suffering from a dysfunctional sexual relationship, which gave Connie some justification for having an affair. According to Gere and director Adrian Lyne, the studio wanted to change the storyline so that the Sumners had a bad marriage with no sex, to create greater sympathy for Connie. Both men opposed the change; Lyne in particular felt that the studio's suggestions would have robbed the film of any drama: "I wanted two people who were perfectly happy. I loved the idea of the totally arbitrary nature of infidelity." The Sumners' relationship was rewritten as a good marriage, with her affair the result of a chance meeting.
Pre-production During preproduction, the producers received a videotaped audition from Olivier Martinez, who was selected for Paul. His character was portrayed as French once Martinez was cast. Lyne said, "I think it helps one understand how Connie might have leapt into this affair—he's very beguiling, doing even ordinary things." Once cast in the role, Martinez, with Lyne's approval, changed some of his dialogue and the scene in which he first seduces Lane's character, while she is looking at a book in Braille. According to Martinez, "The story that was invented before was much more sensual, erotic, and clear.
George Clooney turned down his role to star in Ocean's Eleven. Jennifer Lopez was offered the role of Connie, but turned it down; she felt that the script "wasn't great". In a 2025 interview with Howard Stern, Lopez said she regretted that decision, admitting it still 'haunts' her. She explained that although the script wasn't good, Lyne's direction made it great. Lyne cast Diane Lane as Connie after seeing her in A Walk on the Moon. He felt that the actress "breathes a certain sexuality. But she's sympathetic, and I think so many sexy women tend to be tough and hard at the same time." Lyne also wanted Gere and Lane to gain weight to portray the comfort of a middle-aged couple. In particular, he wanted Gere to gain 30 pounds and left donuts in the actor's trailer every morning.
Lyne asked director of photography Peter Biziou, with whom he made 9½ Weeks, to shoot Unfaithful. After reading the script, Biziou felt that the story was appropriate for the classic 1.85:1 aspect ratio because it "so often has two characters working together in the frame". During preproduction, Biziou, Lyne, and production designer Brian Morris used a collection of still photographs as style references. These included photos from fashion magazines and shots by prominent photographers.
Filming Initially, the story was set against snowy exteriors, but this idea was rejected early on. Principal photography began in New York City on March 22, 2001, and wrapped on June 1, 2001, with Lyne shooting in continuity whenever possible. During the windstorm sequence where Connie first meets Paul, it rained and Lyne used the overcast weather conditions for the street scenes. The director also preferred shooting practical interiors on location, so the actors could "feel an intimate sense of belonging", Biziou recalls. The cinematographer also used natural light as much as possible.
At times, Lyne's directing took its toll on the cast and crew. In a scene taking place in an office, the director pumped it full of smoke, an effect that "makes the colors less contrasty, more muted". According to Biziou, "The texture it gives helps differentiate and separate various density levels of darkness farther back in frame". The smoke was piped in for 18 to 20 hours a day and Gere remembers, "Our throats were being blown out. We had a special doctor who was there almost all the time who was shooting people up with antibiotics for bronchial infections". Lane acquired an oxygen bottle to survive the rigorous schedule.
The film has many explicit sex scenes, including a tryst in a restaurant bathroom and a passionate exchange in an apartment building hallway. Lyne's repeated takes for these scenes were demanding for the actors, especially for Lane, who had to be emotionally and physically fit for the scenes. To prepare for the initial love scene between Paul and Constance, Lyne had the actors watch clips from Fatal Attraction, Five Easy Pieces, and Last Tango in Paris. Lane and Martinez would also talk over the scenes in his trailer beforehand. Once on the set, they felt uncomfortable until several takes in. She said, "My comfort level with it just had to catch up quickly if I wanted to be the actress to play it." Martinez was not comfortable with nudity. Lane said that Lyne would often shoot a whole magazine of film, "so one take was as long as five takes. By the end, you're physically and emotionally shattered."
Lane had not met Martinez before filming, and they did not get to know each other well during the shoot, mirroring the relationship between their characters. A full four weeks of the schedule were dedicated to the scenes in Paul's loft, which was located on the third floor of a six-story building on Greene Street. Biziou often used two cameras for the film's intimate scenes to reduce the number of takes that had to be shot.
Post-production Lyne shot five different endings to Unfaithful based on his experiences with Fatal Attraction, whose initial ending was rejected by the test audience. According to Lyne, he had some debate with the 20th Century Fox officials, who wanted to "make the marriage gray, the sex bad. I fought that. I tried to explore the guilt, the jealousy—that's what I'm interested in." The studio did not like the film's "enigmatic" ending, which they felt failed to punish crimes committed by the characters. It imposed a "particularly jarring 'Hollywood' final line", which angered Gere. Fox preferred the ending where all the moral and narrative issues were tied up.
