Sunburn (1979)

Synopsis
Jake (Charles Grodin), an insurance investigator, is assigned to probe the killing of a wealthy businessman in Acapulco. To help him, he hires a beautiful New York model, Ellie (Farah Fawcett), to act as his wife, and they pretend to be tourists on vacation. Art Carney plays Marcus, a local detective who befriends Jake but gets him into various scrapes. Joan Collins also appears as the suspicious Nera. Sunburn was a made-for-TV movie which featured a pop-song soundtrack blaring from characters' tape recorders that included tunes by Herbie Hancock. The movie was based on the novel The Bind by Stanley Ellin. ~ Michael Betzold, All Movie Guide
