 Throughout the movie, Frankie Avalons character is only referred to  as "The Big Kahuna", and never once is called by his first name. He  is listed as "Annettes Husband" in the end credits. The name  "Frankie" could not be used anywhere in the film, because Avalon  played "Frankie" in the 1960s beach movies and legal issues were  involved since this film was made by a different studio and with  different producers. However, "The Big Kahuna" was actually a  character from the 1959 film "Gidget," rather than from the Beach  Party series.
