Laura is a 1944 American film noir produced and directed by Otto Preminger. It stars Gene Tierney, Dana Andrews, and Clifton Webb along with Vincent Price and Judith Anderson. The screenplay by Jay Dratler, Samuel Hoffenstein, and Betty Reinhardt is based on the 1943 novel of the same title by Vera Caspary.
Once principal photography was completed, Preminger hired David Raksin to score the film. The director wanted to use "Sophisticated Lady" by Duke Ellington for the main theme, but Raksin objected to the choice. Alfred Newman, music director for Fox, convinced Preminger to give Raksin a weekend to compose an original tune. Inspired by a Dear John letter he had once received from a girlfriend, Raksin wrote the haunting theme for which Johnny Mercer later wrote lyrics. It eventually became a jazz standard recorded by more than four hundred artists, including Stan Kenton, Dick Haymes, Woody Herman, Nat King Cole, The Four Freshmen, Charlie Parker, and Frank Sinatra.
