Though not readily apparent at first,
The Unfaithful
is a remake of the 1940 Bette Davis vehicle
The Letter
, which in turn was adapted from the play by W. Somerset Maugham. The locale of the Maugham original has been shifted from the jungles of Malaya to the cozy confines of a middle-sized American town. Ann Sheridan stars as Chris Hunter, who late one night kills a man who tries to attack her in her own home. At least that's her story: it turns out that the dead man had once had an affair with Chris while her serviceman husband Bob (Zachary Scott) was overseas. When it appears as though Chris might have intentionally murdered her assailant, faithful family friend and attorney Larry Hammaford (Lew Ayres) puts his career and reputation on the line by suppressing a valuable piece of evidence. Shorn of the class and race consciousness -- not to mention the eroticism and bitter irony -- of the Maugham original,
is able to move more logically to a happy (or at least satisfying) denouement.
