Rififi (French: Du rififi chez les hommes) is a 1955 French crime film adaptation of Auguste Le Breton's novel of the same name. Directed by American blacklisted filmmaker Jules Dassin, the film stars Jean Servais as the aging gangster Tony "le Stéphanois", Carl Möhner as Jo "le Suédois", Robert Manuel as Mario Farrati, and Jules Dassin as César "le Milanais". The foursome band together to commit an almost impossible theft, the burglary of an exclusive jewelry shop in the Rue de la Paix. The centerpiece of the film is an intricate half-hour heist scene depicting the crime in detail, shot in near silence, without dialogue or music. The fictional burglary has been mimicked by criminals in actual crimes around the world.

After he was blacklisted from Hollywood, Dassin found work in France where he was asked to direct Rififi. Despite his distaste for parts of the original novel, Dassin agreed to direct the film. He shot Rififi while working with a low budget, without a star cast, and with the production staff working for low wages.

Upon the initial release of the film, it received positive reactions from audiences and critics in France, the United States, and the United Kingdom. The film earned Dassin the award for Best Director at the 1955 Cannes Film Festival. Rififi was nominated by the National Board of Review for Best Foreign Film. Rififi was re-released theatrically in both 2000 and 2015 and is still highly acclaimed by modern film critics as one of the greatest works in French film noir.

Tony "le Stéphanois", a criminal who has served a five-year prison term for a jewel heist, is out on the street and down on his luck. His friend Jo approaches him about a smash-and-grab proposed by mutual friend Mario in which the trio would cut the glass on a Parisian jeweler's front window in broad daylight and snatch some gems. Tony declines. He then learns that his old girlfriend, Mado, took up in his absence with gangster Parisian nightclub owner Pierre Grutter. Finding Mado working at Grutter's, Tony invites her back to his rundown flat. She is obviously well-kept, and Tony savagely beats her for being so deeply involved with Grutter. Tony changes his mind about the heist; he now accepts on the condition that rather than merely robbing the window, they will take on the more difficult but more lucrative task of robbing the store's safe. Mario suggests they employ the services of Italian compatriot César, a safecracker. The four devise and rehearse an ingenious plan to break into the store and disable its sophisticated alarm system.

The caper begins with the group chiseling through a cement ceiling from an upstairs flat on a Sunday night. The suspenseful break-in is completed, and the criminals appear to escape without leaving any trace of their identities. However, without the others' knowledge, César pocketed a diamond ring as a bauble for his lover Viviane, a chanteuse at Grutter's club. The heist makes headline news and the four men arrange to fence the loot with a London contact. Meanwhile, Grutter has seen Mado and her injuries, and she breaks off their relationship. Infuriated at Tony's interference in his life, Grutter gives heroin to his drug-addicted brother Rémy and tells him to murder Tony. But then, the other Grutter brother, Louis, shows them the diamond César gave to Viviane and they realize that César, Mario, and Tony were responsible for the jewel theft. Grutter forces César to confess. Forsaking a FF10 million police reward, Grutter decides to steal the jewels from Tony's gang, with Rémy brutally murdering Mario and his wife Ida when they refuse to reveal where the loot is hidden. Tony retrieves it from the couple's apartment and anonymously pays for a splendid funeral for them. He then goes looking for Grutter and stumbles onto the captive César, who confesses having squealed. Citing "the rules," Tony ruefully kills him.

Meanwhile, seeking to force their adversaries' hand, Grutter's thugs kidnap Jo's five-year-old son Tonio and hold him for ransom. The London fence arrives with the payoff, after which Tony leaves to single-handedly rescue the child by force, advising Jo it is the only way they will see him alive. With Mado's help, he tracks Tonio down at Grutter's country house and kills Rémy and Louis while rescuing him. On the way back to Paris, Tony learns Jo has cracked under the pressure and agreed to meet Grutter at his house with the money. When Jo arrives Grutter tells him Tony has already snatched the child and kills him. Seconds too late to save his friend, Tony is mortally wounded by Grutter but kills him as Grutter tries to flee with the loot. Bleeding profusely, Tony drives maniacally back to Paris and delivers Tonio home safely before dying at the wheel as police and bystanders close in on him and a suitcase filled with FF120 million in cash. Jo's wife, Louise, takes her child from the car and leaves the suitcase and the body to police.

The film Rififi was originally to be directed by Jean-Pierre Melville, a later luminary of the heist film genre. Melville gave his blessing to American director Jules Dassin when the latter asked for his permission to take the helm. It was Dassin's first film in five years. He had been blacklisted in Hollywood after fellow director Edward Dmytryk named him a Communist to the House Committee on Un-American Activities in April 1951. Subsequently, Dassin attempted to rebuild his career in Europe. Several such film projects were stopped through long-distance efforts by the US government. Dassin attempted a film L'Ennemi public numero un, which was halted after stars Fernandel and Zsa Zsa Gabor withdrew under American pressure. An attempt to film an adaptation of Giovanni Verga's Mastro-don Gesualdo in Rome was halted by the US Embassy. Dassin received an offer from an agent in Paris, France where he met producer Henri Bérard who had acquired the rights to Auguste Le Breton's popular crime novel Du Rififi chez les hommes. Bérard chose Dassin due to the major success in France of Dassin's previous film The Naked City.

Using his native English, Dassin wrote the screenplay to Rififi in six days with the help of screenwriter René Wheeler, who subsequently took the material and translated it to French. Dassin hated the novel; he was repelled by the story's racist theme in which the rival gangsters were dark Arabs and North Africans pitted against light-skinned Europeans. As well, the book portrayed disquieting events such as necrophilia—scenes that Dassin did not know how to bring to the big screen. Bérard suggested making the rival gang Americans, assuming Dassin would approve. Dassin was against this idea as he did not want to be accused of taking oblique revenge on screen. Dassin downplayed the rival gangsters' ethnicity in his screenplay, simply electing the Germanic "Grutter" as surname. The greatest change from the book was the heist scene, which spanned but ten pages of the 250-page novel. Dassin focused his screenplay on it to get past other events he did not know what to do with. As produced, the scene takes a quarter of the film's running time and is shot with only natural sound, with no spoken words or music.
