After an explorer (Claude Rains) claims that he has seen dinosaurs, an expedition goes to a South American plateau to find them. The mixed bag of people who are on the expedition for good and bad reasons, are stranded on the plateau and have to battle the locals to find a way to escape. Entertaining version of the story, but it is now showing its 1960's origins, especially Jill St John's outfits which are just inappropriate for the jungle. The stop motion effects for the monsters are effective which ae credited to Willis H O'Brien although mainly for his drawings. The film is based on the novel by Arthur Conan Doyle.
