Teenage Caveman (U.K. title: Out of the Darkness) is an independently made 1958 black-and-white science fiction adventure film drama, produced and directed by Roger Corman, and starring Robert Vaughn and Sarah Marshall. Teenage Caveman was released by American International Pictures in July 1958 as a double feature with How to Make a Monster. The film was originally filmed under the title Prehistoric World and some 8x10 publicity stills retained the original title; AIP later changed it. Years later, Corman stated in an interview, "I never directed a film called Teenage Caveman". Lead actor Vaughn stated in an interview that he considered Teenage Caveman to be the worst film ever made. It was later featured on the mocking television series Mystery Science Theater 3000.

In a surprising denouement provided by the old man after his death, the truth is revealed in voice-over as the tribesmen page through his book: He was actually a survivor of a long-ago nuclear holocaust, forced to live for decades inside his now-ragged, discolored and bulky radiation suit (which is implied to have once been
