The Valley of Gwangi

The discovery of a midget horse thought to be of a species fifty million years old prompts members of a Wild West show to venture into Mexico's Forbidden Valley in search of world-wide fame and untold wealth. But they are met by prehistoric monsters including Gwangi a giant dinosaur that decimates their ranks. Spectacular special effects from Academy Award-winner Ray Harry Hausen (Clash of the Titans the Beast from 20000 Fathoms).
