Don't Make Waves is a 1967 American sex farce (with elements of the beach party genre) starring Tony Curtis, Claudia Cardinale, Dave Draper and Sharon Tate. Distributed by Metro-Goldwyn-Mayer, the film was directed by Alexander Mackendrick and is based on the 1959 novel Muscle Beach, by Ira Wallach, who also wrote the screenplay.
The film depicts a series of romantic triangles between different groupings of the principal cast and supporting players among several backdrops involving Southern California culture (swimming pools, bodybuilding, beach life, fantastic real estate, mudslides, metaphysical gurus, etc.).
Carlo Cofield, a tourist visiting California's west coast, has not even arranged lodging when his car is smashed by a reckless driver. She is carefree, attractive Laura Califatti, who offers him to sleep that night on her couch.
This displeases Rod Prescott, a wealthy swimming-pool builder, because Laura is his mistress. After being kicked out, Carlo tries to sleep on the beach and nearly drowns. He is rescued by mouth-to-mouth resuscitation from a gorgeous surfer who goes by the name "Malibu."
Carlo begins a romantic pursuit of the much-younger woman. After renting a house near the ocean, Carlo cons a sweet but naive bodybuilder, Harry, who is Malibu's boyfriend, that having sex is harmful to his body. He also bribes a phony psychic, "Madame Lavinia," who is actually a man, to discourage Harry from seeing Malibu anymore.
Rod decides to give the persistent Carlo a job as a pool salesman. The affair with Laura is discovered by Rod's wife, Diane, who demands a divorce. As a quarrel develops with everyone present, a mudslide caused by a sudden storm makes Carlo's house slide down a cliff. By the time everyone is saved, they pair off with the romantic partners they deserve.
Upon its release on June 20, 1967, Don't Make Waves received generally mixed reviews. By the time the film was released, the popularity of beach films and films that related to California beach culture had begun to wane as had the popularity of Tony Curtis as a matinee idol. In American Prince, his 2009 autobiography, Tony Curtis wrote of making Don't Make Waves, "The plot was utterly ridiculous, but I agreed to appear in the film because I got a percentage of the gross." The film would go on to earn $1.25 million at the box office.
Don't Make Waves has since received more positive comments from reviewers, such as Leonard Maltin who describes it as "a gem", and makes note of the "good direction, funny performance by Sharon Tate and a catchy title song...".
Don't Make Waves was released to DVD by Warner Home Video's Warner Archive on June 27, 2011 as a burn-on-demand Region 1 widescreen DVD.
