The behind-the-scenes story of the quintessential film noir and cult classic, Billy Wilder’s Double Indemnity—its true crime origins and crucial impact on film history—is told for the first time in this riveting narrative published for the film's 80th anniversary. From actual murder to magazine fiction to movie, the history of Double Indemnity is as complex as anything that hit the screen during film noir’s classic period. A 1927 tabloid sensation “crime of the century” inspired journalist and would-be crime-fiction writer James M. Cain to pen a novella. Hollywood quickly bid on the film rights, but throughout the 1930s a strict code of censorship made certain that no studio could green-light a murder melodrama based on real events. Then in 1943 veteran scriptwriter and newly minted director Billy Wilder wanted the story for his third movie. With tentative approval from the studio he hired hardboiled novelist Raymond Chandler to co-write a script that would be acceptable to industry censors. Director Wilder then cajoled a star cast into coming aboard: the incomparable Barbara Stanwyck in her unforgettable turn as the ultimate femme fatale; alongside Fred MacMurray, going against type as her accomplice; and Edward G. Robinson as a dogged claims investigator. Wilder kept Chandler on for the entire shoot, and other key collaborators were cinematographer John Seitz, costume designer Edith Head, and composer Miklôs Rôzsa. With all these talented contributors, the final film became one of the earliest studio noirs to gain critical and commercial success, including being nominated for seven Oscars. It powerfully influenced the burgeoning noir movement, spawned many imitators, and affected the later careers of all its cast and crew. Double Indemnity’s impact on filmmakers and audiences is still felt eight decades since its release. Authors Alain Silver and James Ursini tell the complete, never-before-told history of writing, making, and marketing of Double Indemnity in their latest and most provocative work on film noir: From the Moment They Met It Was Murder.
