'It eats meat! Us!!' It is a Tyrannosaurus, ruler of a lost world hidden within a dormant polar volcano. US are members of expedition led by a big game hunter and überzillionaire (Richard Boone). And eats - well, you get the idea, tyrant lizard fans! Arthur Rankin, Jr.. and Jules Bass, who charmed families with the Year Without a Santa Claus and more animated and stop-motion holiday heart-warmers, relied on dinomight for the Last Dinosaur, the sort of thrill-a-minute popcorn-seller that gives bad movies a good name. Join the adventurers as they encounter a perilous array of prehistoric beasts, a tribe of savage cavemen and a T. Rex who, despite it's less-than-special effect appearance, can kick some serious Triceratops butt.
