A marvelous cast (Paul Lynde! Don Rickles! Linda Evans!) is collected in what is possibly the most beloved of the 1960's Frankie Avalon/Annette Funicello beach movies. In this installment, Bonehead (Jody McCrea) falls in love with a mermaid, not-so-threatening biker Eric Von Zipper (Harvey Lembeck) terrorizes the beach, Frankie skydives, surfs, and sings some songs, and Annette sings and looks simply smashing in a two-piece. Throw in an appearance from silent screen legend Buster Keaton and a score by lounge music god Les Baxter, and you have a can't-miss time capsule from a simpler, possibly better, time.
