An Oscar nomination finally came Hammer’s way, recognizing Jim Danforth and Roger Dicken’s stop-motion visual effects work on the studio’s return to the prehistoric well following One Million Years B.C. In this tale of two rival tribes, the Romeo-and-Juliet relationship of Victoria Vetri (1968 Playboy Playmate of the Year) and Robin Hawdon is overshadowed—in several respects—by dinosaurs, not to mention giant crabs, lizards, and snakes. This was Guest’s final feature for Hammer.
