The polished Gazzara, the bumbling Ritter, and the ultra-hip Novak work for a detective agency. Over the course of the film, all three become romantically involved with the women they are shadowing--Hepburn, Hansen, and Stratten playing the objects of their affection. Breezy and carefree, THEY ALL LAUGHED suffers from a weak, hard-to-grasp structure. As lovable as the characters and their situations are, one is never quite sure where the film is leading. The film spent nearly a year on the shelf until director Bogdanovich bought it from Fox and distributed it himself. It is unfortunate that the movie's chief interest lies in the presence of former Playboy Playmate Stratten, who was murdered by her husband before the film was released. The circumstances surrounding her death were frighteningly similar to those that Bogdanovich sets up in his film. Stratten is pursued by Ritter while evading the watchful eye of her jealous husband. In real life Stratten was having an affair with Bogdanovich during the filming of THEY ALL LAUGHED and was being trailed by a detective hired by her husband, Paul Snider.
