| Steven Keats and Richard Boone |
"A creature forty feet tall and weighing eight tons with the mind of a pea has just destroyed one of the greatest minds of the century."
Masten Thrust Jr. (Richard Boone of I Bury the Living) is not only a famous hunter but one of the world's wealthiest men. He has developed a vehicle called the Polar Borer, that uses lasers to drill through the Polar Ice Cap, discovering a hidden world in a prehistoric valley below that is warmed by a volcano. Four men have already died at the teeth of a T-Rex, that appears to be the only one of its kind, although there are other dinosaurs in the valley. Returning to this land with the only survivor of the first expedition, Chuck (Steven Keats), Thrust also brings along Professor Kawamoto (Tetsu Nakamura of The Manster); an expert and silent seven foot tall tracker named Bunta (Luther Rackley); and a perky photographer named Francesca (Joan Van Ark). Although the original plan is only to study the tyrannosaurus, when it proves aggressive and even squashes the poor professor underfoot, Thrust determines to destroy the creature. But then the big beast snatches up the Polar Borer in its teeth and the whole group is stranded in the valley with time running out ...

| Bantu takes after T-Rex with a spear -- good luck with that! |
Verdict: Hardly the "last" dinosaur we've ever seen in film. **1/4.
