Teenage Caveman (2002)

Teenage Caveman is Larry Clark's 2001 remake, trading the original's atomic-age monster plot for a feral tribe of young survivors scraping by in a post-collapse wasteland. Tiffany Limos plays one of the tribe members, and the archive holds 1 nude scene of her from the film. It's a single clip, but it's an unclothed scene, not a body double or a blink-and-miss cutaway.
