They All Laughed is a 1981 American romantic comedy film directed by Peter Bogdanovich and starring Audrey Hepburn, Ben Gazzara, John Ritter, Colleen Camp, Patti Hansen, and Dorothy Stratten. The film was based on a screenplay by Bogdanovich and Blaine Novak. It takes its name from the George and Ira Gershwin song of the same name. The film is set in New York City, largely filmed outdoors on the streets, and tells the story of three private detectives investigating two beautiful women for infidelity. The detectives eventually wind up romantically pursuing the women, who turn the tables on them. The film is also a candid look at love and sex in New York City in the early 1980s. Plot The New York-based private investigation firm Odyssey Detective Agency employs three agents: the middle-aged, womanizing John Russo, the younger, hippie-ish Arthur Brodsky, and the nervy and anxious Charles Rutledge. Their cantankerous boss, Leon Leondopolous, tries to keep his bumbling agents in line while carrying on a poorly-disguised affair with his secretary Amy. Odyssey is investigating two separate married women: Angela Niotes, the aged but glamorous wife of a British tycoon, and Dolores Martin, a beautiful blonde. While attempting to follow Angela from the Manhattan heliport, John meets a taxi driver named Deborah Wilson. The two are instantly infatuated, and John makes plans to see Deborah (whom he calls "Sam") later that night. At the same time, Charles falls for Dolores as he spies on her in the lobby of a hotel. Arthur (who juggles a series of passionate romances throughout the film) is worried for each of his co-workers, but assists each of them in growing closer to their objects of affection: he helps John get away from his on-again off-again partner, country singer Christy Miller, and devises a plan for Charles to have a conversation with Dolores at a roller rink. He learns that Dolores is indeed cheating on her husband with Jose, a playboy with whom she plans to elope. The next morning, John recounts his tryst with Deborah to Leon; he worries that he has become too old for younger women. Meanwhile, Christy, who has figured out what John has done, decides to get back at him by starting a relationship with Charles. The two head to Midtown, where they run into Dolores at an upscale clothing store. Christy later tries to initiate a sexual encounter with Charles,
