Title: Lady in the Lake
Content:  Making Lady in the Lake was Robert Mongtomery's idea. He had stood in as director for John Ford on They Were Expendable when Ford got sick, and he wanted to direct again. He convinced MGM to buy the rights to Chandler's latest novel, The Lady in the Lake, for which the studio paid a reported $35,000. Since Chandler had co-written the screenplay for Double Indemnity with Billy Wilder, for which he received an Academy Award nomination, and then had received another nomination for his script for The Blue Dahlia, Montgomery wanted Chandler to write the screenplay for Lady in the Lake. This resulted in the 195-page screenplay which has been called "remarkably bad". Montgomery then brought in Steve Fisher to

Content:  Lady in the Lake is a 1947 American film noir that marked the directorial debut of Robert Montgomery, who also stars in the film. The picture also features Audrey Totter, Lloyd Nolan, Tom Tully, Leon Ames and Jayne Meadows. The murder mystery was an adaptation of the 1943 Raymond Chandler novel The Lady in the Lake. The film was Montgomery's last for Metro-Goldwyn-Mayer (MGM), after eighteen years with the studio. Montgomery's ambition was to create a cinematic version of the first-person narrative style of Chandler's Philip Marlowe novels.

Fisher made major changes, such as re-setting the time of the film to the Christmas holiday, and dropping all the scenes which took place at the lake. Chandler objected to these changes, and was insulted that another writer was changing his story, but he still insisted that he be given a screenplay credit, until he saw the final result, when he demanded that his name be removed from the film. Montgomery tried a technique that had often been talked about in Hollywood but never used in a major film: he used the camera as the protagonist of the film. Other characters talk directly

The movie was also unusual for having virtually no instrumental soundtrack, the music in the film being instead provided by a wordless vocal chorus. The film did not use Raymond Chandler's own 195-page screenplay adaptation dated July 5, 1945 which he wrote for MGM, but instead used a 125-page version written by Steve Fisher, which was filmed two years later. The film's script changes the novel's midsummer setting to Christmastime, frequently using holiday themes as an ironic counterpoint to the grim aspects of the story. The opening credits are shown on a series of Christmas cards, which turn out to be concealing a gun.
