American International Pictures’ Dr Goldfoot And The Bikini Machine (released 6 November 1965): the Beach Party Gang goes sci-fi horror comedy, starring the Ski Party (1965) pair of Frankie Avalon and Dwayne Hickman, and cameos from almost everyone else, including Annette Funicello and Harvey Lembeck.
“Dr. Goldfoot hopes to ensnare the fortunes of the world’s wealthiest men with the aid of the beautiful bikini-clad robots he manufactures in his laboratory. Diane, the prize beauty of Goldfoot’s assembly line, is sent out to trap wealthy playboy Todd Armstrong, whom she succeeds in marrying and in persuading to sign over much of his wealth. Secret Intelligence Command’s Craig Gamble, in love with Diane, blunders into the plot and, trying to help Armstong, falls into Goldfoot’s torture chamber, where he and Armstrong are terrorized by various devices, including a swinging pendulum. They escape, however, and are pursued by Goldfoot and his inept assistant, Igor.” Turner Classic Movies.
