Perhaps the single best example of a film noir movie, Double Indemnity (1944), stars Fred MacMurray, Barbara Stanwyck, and Edward G. Robinson. Based on a novel written by James Cain, the screenplay was co-written by Billy Wilder and the amazing Raymond Chandler.
Set in 1938 California, the story is based on the true-life 1927 murder of a married Queens, New York woman's husband who was killed by the woman's boyfriend after she took out a large insurance policy that contained a double-indemnity clause. In this movie, Phyllis Dietrichson (played by Stanwyck) takes out a life insurance policy on her husband with the help of insurance salesman-soon-to-be-turned-murderer Walter Neff (played by MacMurray). Robinson plays Barton Keyes, Neff's co-worker and a very suspicious claims adjuster who suspects Phyllis Dietrichson might have had something to do with her husband's sudden death.
This movie is an hour and forty-seven minutes of pure movie love. The film was nominated for seven Academy Awards [Best Picture, Best Actress in a Leading Role (Barbara Stanwyck), Best Director, Best Writing-Screenplay, Best Cinematography, Best Sound Recording, and Best Music (Scoring of a Dramatic or Comedy Picture)], though it won none.
