Beach Party (1963)

Dolores (Annette Funicello) and Frankie (Frankie Avalon), attractive young surfers in Southern California, are just out for a good time. Their relaxed lifestyle fascinates Professor Sutwell (Bob Cummings), an anthropologist who decides to study the social lives of teens. A series of beach-themed films would follow the blueprint set by this one, which hinges on romantic rivalries, rugged motorcyclists, an attempted crime and plenty of handsome people.
