This classic thriller from director Billy Wilder is one of the best-loved examples of film noir ever made. Based on a short story by James M Cain (author of The Postman Always Rings Twice), and with a crackling screenplay co-written by Raymond Chandler, it follows definitive femme fatale Barbara Stanwyck as she seduces insurance salesman Fred MacMurray into doing away with her husband to claim his life insurance. But dogged claims investigator Edward G Robinson smells a rat. Wilder keeps the sexual tension tight and displays a mastery of visualisation on key plot points. Some may find Stanwyck less sexy than her character should be, but that's a minor quibble when the dialogue's as good as this: "I loved you and I hated him, but I didn't do anything about it 'til you came along." Wilder was nominated for an Oscar, as was John F Seitz's cinematography and Miklos Rozsa's atmospheric score. In the best actress category, Stanwyck lost out to Ingrid Bergman for Gaslight.

A seductive housewife draws an insurance salesman into a plot of adultery and crime to collect on her husband's life insurance.
