Caveman (1981) is a delightfully absurd prehistoric comedy that delivers laughs through its inventive physical humor and clever anachronistic gags. The film follows Atouk (Ringo Starr), a scrawny but clever caveman who becomes infatuated with the beautiful Lana (Barbara Bach). His quest for her affection is complicated by the brutish Tonda (John Matuszak), the tribe's massive and dim-witted leader who claims Lana for himself. The resulting rivalry sets off a chain of slapstick misadventures as Atouk uses his wits to outmaneuver his physically superior opponent.

Directed by Carl Gottlieb, Caveman excels in its visual comedy and playful approach to Stone Age life. The film is famously light on dialogue, using a made-up caveman language, which allows the physical performances to shine. Ringo Starr proves surprisingly adept at silent comedy, while Shelley Long and Dennis Quaid appear in early supporting roles. The movie's charm lies in its simple, universal story of the underdog fighting for love, told with genuine warmth and creativity.

While not a critical darling, Caveman has earned a loyal cult following for its sheer silliness and heart. It's a perfect watch for fans of lighthearted, family-friendly comedies or anyone curious about Ringo Starr's film work outside The Beatles. The 91-minute runtime breezes by with inventive sight gags, including encounters with stop-motion dinosaurs. For an undemanding, good-natured comedy that doesn't take itself seriously, Caveman remains an entertaining watch online.
