Unfaithfully Yours (1984 film)

Unfaithfully Yours is a 1984 American romantic comedy film directed by Howard Zieff, starring Dudley Moore and Nastassja Kinski and featuring Armand Assante and Albert Brooks. The screenplay was written by Valerie Curtin, Barry Levinson, and Robert Klane based on Preston Sturges' screenplay for the 1948 film of the same name. The original music score is by Bill Conti and the song "Unfaithfully Yours (One Love)" was written for the film and performed by Stephen Bishop.

Plot
Claude Eastman is a composer and the conductor of a prestigious symphony who has recently married beautiful Daniella, a much younger woman. While traveling, he sends a message to his friend Norman Robbins to keep an eye on his wife, but the message is garbled by Claude's Italian valet Giuseppe, and Norman hires a private detective named Keller to investigate Daniella.

The private eye's report, which comes with a fuzzy video, is that Daniella had an assignation with a man who, by wearing Argyle socks, appears to be Maxmillian Stein, a handsome violinist with the orchestra – and Claude's protégé – who is well known as a ladies man. In fact, Max merely used Claude's flat for an assignation with Norman's wife Carla.

Claude attempts to surprise Max and Daniella together, leading Max and Carla to believe that he knows about their affair. When Max eventually meets Daniella, it is at a restaurant where Claude, overwhelmed with jealousy, duels Max with violins by playing a Csárdás, the famous composition of Vittorio Monti.

Claude separately confronts both Daniella and Max. Daniella feels guilty because she is keeping the affair a secret from her husband, while Max apologizes only for using Claude's flat for the affair. Not realizing that Claude believes Max was meeting Daniella, neither of them clarifies that Max was meeting Carla, and Claude takes this as confirmation of his suspicions, while he is enraged by their apparent lack of contrition. He plots to kill both of them.

As he conducts Tchaikovsky's "Violin Concerto", a plan to kill Daniella and frame Max for the murder runs through his mind, leaving him laughing hysterically, but afterwards, when he tries to carry out his plan, unforeseen circumstances intervene.

Keller realizes his mistake after seeing Carla leave Claude's apartment on the tape. After failing to catch Claude at the concert to explain, he goes to Claude's flat and interrupts him while he is struggling to carry out his murder plan. Daniella is initially furious when she learns the truth - seemingly more because Claude believed she was unfaithful than because he planned to kill her - and leaves. Claude rushes after her and explains that he loves her but does not think he can stop being jealous, and the two reconcile.
