Inc. "I didn't do any research about detectives", said Bogdanovich. "I never even went into a detective's office, but that didn't matter to me. That's not what it was about, that was just the disguise I hung my hat on." "Audrey Hepburn's story in the movie is Audrey Hepburn's story in life", said the director. "She was living with a man, her second husband, he was cheating on her, and she basically stayed with him because of the child." The film was shot on location in New York City during the spring and summer of 1980. Bogdanovich would often write scenes and give them to the actors just before they were shot, to give the film a feeling of freshness. Country music is prominently featured. According to Bogdanovich, in the first version of the script, the character of Christy was going to be a jazz singer, singing jazz standards, but then: There was a short, very short, very brief, vogue of country music in New York. About 30 seconds. And so I changed it. I like country music. I fell in love with it on Last Picture Show. In fact, I wrote a couple of country songs. The phrase "One Day Since Yesterday" was something Dorothy said to me in a card. I liked the phrase.

Hepburn's son plays the part of Jose, though the part of her son in the film is played by Glenn Scarpelli. According to Bogdanovich, Hepburn and Gazzara had had an affair prior to the filming, though evidently this had fizzled by the time filming began, and Gazzara's ongoing divorce made further contact inadvisable. (Commentors have not agreed as to whether Gazzara and Hepburn have good onscreen chemistry in They All Laughed). Bogdanovich's real-life daughters portray John Russo's daughters, who along with Arthur (pretending to be Russo's son in a crucial scene), are enlisted to win Angela Niotes's trust. More implicitly, Arthur, who acts primarily as a facilitator to the others' romances, is portrayed by one of the film's screenwriters, Blaine Novak. Charles, who pursues Dorothy Stratten's character, wears director Peter Bogdanovich's trademark oversized plastic-framed eyeglasses, perhaps a reference to Bogdanovich's initial guilt and subsequent acceptance
