The Ghost in the Invisible Bikini

This film proved beyond a shadow of a doubt that the "Beach Party" genre was dead. After the previous film with Frankie Avalon and Annette Funicello, American International thought they could pull the two of them back for one final picture. However, by the time the plans were announced Avalon was more interested in other roles and Funicello was busy raising her family. Instead we get Tommy Kirk and Deborah Walley who, unfortunately, don't have the chemistry that Frankie and Annette had together. The "Beach Party" series was one of the most enduring in film history. Too bad it had to go out with a whimper instead of a bang.
