How to Stuff a Wild Bikini is considered to be the strangest of the “Beach Party” movies. Frankie (Frankie Avalon) is off in the navy, serving in the South Pacific, and nervous about all of the guys that will be hitting on Dee Dee (Annette Funicello) back at the beach. He makes a deal with an eccentric white witch doctor (Buster Keaton), who conjures up a woman named Cassandra (Beverly Adam) who is irresistible to all men, and she attracts all of the guys on the beach. But complications ensue when lunatic advertising man Mickey Rooney decides to try and make Cassandra a new national sex symbol, and she gets noticed by nutsy bike gang leader Erik Von Zipper (Harvey Lembeck), who vows to have her. With enough plot complications to rival A Midsummer Night’s Dream, Wild Bikini is laced with satire and some surprisingly good music. ~ Bruce Eder, Rovi
Trivia
This was the last beach party movie for both Annette Funicello and Frankie Avalon. Avalon accepted his role in the film (he appears for only seven minutes) with quite a bit of reluctance, as his career was going very well, acting in five features in 1965.
Beverly Adams, who portrays Cassandra in the film, is now better known as Beverly Sassoon, ex-wife of Vidal Sassoon and the mother of the late actress Catya Sassoon.
Marianne Gordon, who portrays Chickie in the film, is now better known as Marianne Rogers, one of the stars of Hee Haw and the ex-wife of Kenny Rogers.
Beach Boy Brian Wilson appears here as…well, a beach boy.
Beautiful Luree Holmes is the daughter of James Nicholson, one of the founders of American International Pictures.
Ned Wynn, the son of actor Keenan Wynn, appears in the film as a beach boy. Wynn later became a successful writer.
Jo Collins, who appears here as a beach girl, was Playboy’s Playmate of the Year in 1965. Collins was once married to baseball player Bo Belinksy.
Bewitched star Elizabeth Montgomery makes a cameo appearance near the end of the film as Buster Keaton’s daughter (she even twitches her nose). At the time, Montgomery was married to director William Asher.
Annette Funicello is seen only fully clothed in this film (no bathing suits) because she was noticeably pregnant with her first child while the film was being shot.
