Two Lost Worlds

When the American clipper ship "The Queen" is attacked by pirates off the Hebrides in 1830, Mate Kirk Hamilton is injured and must be put ashore at Queensland Colony, Australia, for treatment and recuperation. There, he meets and falls in love with Elaine Jeffries, daughter of the magistrate and all-but-fianc?e to rancher Martin Shannon. She also finds herself attracted to Kirk, and a rivalry develops between the two men. Meantime the pirates, led by Captain Hackett, decide to raid the colony and, in the process kidnap Elaine and her friend, Nancy. Kirk and Shannon lead the pursuit, having not only the romantic triangle to resolve but the pirates to overcome and, along the way, being stranded on a volcanic island inhabited by dinosaurs.

James Arness, star of THE THING, is the captain in this schlock fantasy feature about a group of adventurers who are shipwrecked on an island populated with prehistoric creatures. Amongst the time-forgotten animals are mastodons and giant vultures, although most of the monster scenes are taken from stock footage.
