This relict from the 1950’s type of cinema bursts into the swinging sixties trying the same formula that had worked for 15 years. Unfortunately for them it fails to work. At all. Ward Ramsey is a third rate Peter Graves wanna be. In fact, according to rumor this was supposed to be a Steve McQueen role. Yeah, sure. Bullitt vs. Dinosaurs, that would be entertaining, but the director here couldn’t pull off a paint by numbers picture. Neither could the special effects department, the effects are particularly bad on this film considering the age. If you aren’t Ray Harryhausen don’t even try to pretend you can do his skills. The film tries to cover the cheap effect with terrible comic relief insulting the only interesting character (the caveman) and factors in an annoying island kid, a lazy black guy, a drunk Irishman, a woman who faints underwater, and The White Man saving the day thanks to White Man technology. Yeesh. I will repeat that the kid was annoying as he is terrible. Imagine any of the Kens from the Gamera movies, make him Mexican and named Julio, and you get this kid.
