The shot of Dustin Hoffman through Anne Bancroft’s raised leg in The Graduate and the meticulous historical research behind Mel Brooks’ History of the World: Part I are just two of Harold and Lilian Michelson's many contributions to the seventh art. They came to Hollywood in the 1950s, when Harold was hired to design movie posters. Before long, he was storyboarding films such as Cecil B. DeMille’s The Ten Commandments and William Wyler’s Ben-Hur. As for Lillian, she soon became Hollywood's most sought-after researcher, working on such films as Alfred Hitchcock's The Birds and Roman Polanski’s Chinatown. This documentary tells the story of this couple, often referred to as Hollywood’s secret weapon.
