Hammer follows up their earlier Stone Age features "One Million Years B.C." and "When Dinosaurs Ruled the Earth" with another epic about primitive man. As written by veteran Hammer producer & writer (and sometime director) Michael Carreras, it's not STRONG on story but is relatively easy to understand and take. There is nothing in the way of dialogue as we typically understand it; all the cave dudes and gals speak in grunts only.
Basically, the story can be simplified as thus: a power struggle between a "fair" caveman (Tony Bonner, "Quigley Down Under") and a "dark" one (Robin John), as they fight for control of a tribe. Assorted other tribesmen and women are played by the likes of Brian O'Shaughnessy ("The Gods Must Be Crazy"), Sue Wilson, Rosalie Crutchley ("The Haunting" '63), and Marcia Fox ("Old Dracula").
The performances are generally amusing. Bonner and John are fun as the macho opponents, as is Crutchley in what basically amounts to a "Stone Age witch doctor" role. The guys often take centre stage, although it's Norwegian sexpot Julie Ege ("The Seven Brothers Meet Dracula") that's top billed. She and Fox make for very fine eye candy, but they're never as in the foreground as the advertising would have you believe.
Accompanied by atmospheric music by Mario Nascimbene, who also did the score for those other pictures, the movie is attractively shot by Vincent G. Cox on various Namibia and South Africa locations (with some studio work as well). Much of its "creatures" are animals living today, with the exception of a goofy man-in-a-costume thing seen in a cave sequence.
While this isn't as effective overall as Hammers' previous forays into the genre, it still makes for some agreeable entertainment. It IS fairly realistic, however: at no point do humans share the screen with dinosaurs.
Six out of 10.
