The Unfaithful

The Unfaithful is a 1947 murder mystery starring Ann Sheridan, Lew Ayres and Zachary Scott, and directed by Vincent Sherman. Regarded by some as a film noir, the picture is based on the W. Somerset Maugham-penned 1927 play and William Wyler-directed 1940 film The Letter, which was reworked and turned into an original screenplay by writers David Goodis and James Gunn.
