Teenage Caveman comes with a perfect exploitation title from the AIP poster factory they frequently used to devise the title first and then a film to go with it. That said, it is not a title that has much relevance to the film. Or even aptness for that matter Robert Vaughn looks to be all of about 30 for the supposed teenager he is supposed to be playing (Vaughn was 26 at the time). Of course, what was happening was that Roger Corman and AIP were exploiting the success that came about after Herman Cohen, another producer at AIP, had had when he made I Was a Teenage Werewolf (1957) and I Was a Teenage Frankenstein (1957). A host of other such teenage titled films were quickly shuffled out indeed, Corman had just finished making the non-genre Teenage Doll (1957) about girl gangs.
While Teenage Caveman is an exploitation movie, it has an inventive script. Screenwriter R. Wright Campbell structures it as a classic conceptual breakthrough story. He uses the familiar theme of championing a breakthrough of knowledge over superstition and tradition. In the unique twist ending, when the lead character makes the discovery about the world, the film manages to ingeniously turn the audiences expectations on their head. In so doing, the film turns from what one originally perceives to be a routine One Million B.C. (1940)-styled prehistoric drama into a post-holocaust film. It is a unique and ingenious twist. Indeed, the same twist ending appears to have been mimicked by both Planet of the Apes (1968) and M. Night Shyamalans The Village (2004).
Unfortunately, the films ideas remain far superior to Roger Cormans execution of them. It is an A-budget idea trapped in the guise of a Z-budget film. The film has been made extremely cheaply. Lizards are substituted for dinosaurs; there are some shoddy monster and bear suits; and the holocaust is depicted by monster footage from other AIP movies, including Day the World Ended and The She-Creature (1956). When the cavemen are attacked by a horde of dogs, you can see the extras grabbing onto the dogs that seem to be trying to flee. Roger Cormans direction is extremely routine the film has been shot quickly and the camera indifferently placed for the most part.
In 2001, the title of the film was borrowed for one of the Creature Features package of cable movies, all new films that recycled old AIP titles. Teenage Caveman was borrowed to become the worthwhile Teenage Caveman (2001), which proved to be the best of the Creature Features series. Although Teenage Caveman 2001 uses a post-holocaust setting, it is not a remake and is otherwise unrelated to this film.
