The Beatles’ Ringo Starr is Atouk, the caveman of the title. As the leader of a rag-tag group of cavemen considered inferior by a larger group of cavemen, Atouk has his work cut out for him when he sets his sights on the beautiful Lana (Barbara Bach). Trouble is … Lana belongs to Tonda (John Matuszak) the leader of the “superior” cavemen. Undeterred, Atouk sets out to win Lana’s hand while being pursued by the caveman-crazy Tala (Shelley Long) and fending off some very hungry dinosaurs. Caveman is directed by Carl Gottlieb (screenwriter Jaws).
