Director: Kevin Connor. Cast: Doug McClure, Peter Cushing, Caroline Munro

The ever-heroic McClure and dotty scientist Cushing travel to the Earth’s core (in a giant drill!) where they discover a race of prehistoric people (all of whom speak excellent English) under the control of telepathic pterodactyls! Caroline plays a scantily clad native girl and the magnificently unconvincing dinosaurs are portrayed by a bunch of guys in rubber suits. The wigs worn by the natives are a special treat.
