Sizzle Beach, U.S.A is a 1986 independent film starring Kevin Costner, Terry Congie, Leslie Brander, and Roselyn Royce. Although the movie was filmed in the year 1974, it was not released until 1986, when Kevin Costner became well known.
Three, young women team up to rent a beach house in Malibu. One of them lands a job in a high school thanks to an investment broker she meets jogging along the beach. Another is taking acting lessons and enjoys horseback riding, though the young owner of the stable, John Logan (Kevin Costner), turns out to be more interesting than the riding itself. And the third woman practices her guitar, shuns the owner of the studio where she records, and hangs out with her hunk cousin Steve, the fourth roommate in the house.
