A loose remake of the 1940 special effects extravaganza with Victor Mature, Hammer's version of the life and times of cavemen and women again cheerfully neglects a few million years of evolution and has our antecedents living side by side with the brontosauri. There's a simple story about lovers from different tribes, and Welch grunts beautifully clad only in a few bits of bunny fur, but the real stars are Ray Harryhausen's superbly animated dinosaurs. It was Hammer's biggest box-office hit and inaugurated a cycle, but the more cheaply made sequels were no match for the ferocious reptile fights on display here.
