Teenage Caveman is a 2002 science fiction-horror-teen film directed by controversial filmmaker Larry Clark. It was made as part of a series of low-budget made-for-television movies loosely inspired by B movies that Samuel Z. Arkoff had produced for AIP. The film reused the title and basic premise from the original 1958 film Teenage Caveman, but it is not a remake of the earlier film.
The film is set in a post-apocalyptic future, where the vast majority of humanity has died due to a viral epidemic. The remaining humans have reverted to primitive tribalism.
