Operation Bikini also released as The Seafighter is a film released in 1963 by American International Pictures. It was directed by Anthony Carras and starred Tab Hunter, Frankie Avalon, and Scott Brady.
The casting was aimed to capture a varied audience. While Operation Bikini was nominally a World War II war movie, it shared a number of cast members — Avalon, Jody McCrea, and Eva Six — with American International's Beach Party (soon to become a franchise), and thrown into the mix were character actor Jim Backus, former screen heartthrob Tab Hunter, and Gary Crosby (son of Bing). Avalon even sings in two musical interludes — which were shot in color, despite the rest of the movie's being shot in black and white.
