Sweet Beat (U.S. title: The Amorous Sex) is a 1959 British 'B' black-and-white musical film directed by Ronnie Albert and starring Julie Amber, Sheldon Lawrence and Irv Bauer. The screenplay was by Ron Ahran based on a story by Sheldon Stark. It includes appearances by several American pop acts including The Melo-Kings and The Five Satins.

Bonnie Martyn, winner of a holiday camp beauty contest, heads to London seeking fame as a singer. She is promised a record deal, and is tricked into going to New York. She is eventually reunited with her boyfriend Bill Lacey.

Filming locations included Butlin's holiday camps at Clacton-on-Sea and Cliftonville, and London's The Stork Room, run by Al Burnett.

The film featured the following songs:

In 1959 a 7-inch double A/B side EP was released in the UK with "Tonite Tonite", "I Remember", "Boppin' at the Hop" and "Luva Luva Love Me" (Top Rank Records, JKR 8007).

The Monthly Film Bulletin wrote: "A mild and artless warning to the stage struck, relying on striptease, "pop" numbers and holiday camp and night club backgrounds for its teen-age appeal. Direction and performance are very uneven."

In British Sound Films: The Studio Years 1928–1959 David Quinlan rated the film as "poor", writing: "Bottom-budget pop musical/moral warning has that home-made look."

The film was released on DVD in 2009 by Pegasus Entertainment.
