These islanders have enormous eyes and allegedlly their ascendants were from lost continent of Atlantis . Their Spawning Ground... The Ocean Epths ! Forgotten by nature .. invaded by modern man...half human...half fish!
An adventure movie with thrills , emotion , shootouts , gorgeous photography and lots of underwater scenes. The tale is silly and laughable but effects and action are quite well . Some illogic parts in the plot are more than compensated for the excitement provided by the underwater images , the colorful coral reef and bikini-dressed mermaid Leigh Christian. It follows in the wake of the films directed by Kevin Connor of the 70s set in fantastic islands such as "Land that Time forgot" , "At the Earth's Core" , "Warlord of Atlantis" , "The People that Time Forgot" , usually starred Doug McClure or Patrick Wayne himself . An agreeable cast mostly formed by B-actors as John Wayne's son : Patrick Wayne , John Ashley , Sid Haig , George Nader and Vic Díaz , Eddie Romero's regular .
It displays a colorful cinematography that's the best factor of the movie , being shot on location in the Philippines Islands . This cheesy motion picture was professionaly directed by Eddie Romero , though has several flaws and gaps . This Philippino director usually collaborated with John Ashley and Roger Corman and he made a lot of films of exploitation and all kinds of genres as Terror, Women In Prison , Adventures , Wartime , Thrillers , outstanding the following ones : Black Mama White Mama , Savage Sisters , Terror is a Man , Day of the Trumpet, Mad Doctor of Blood Island , The Woman Hunt , Raiders of Leyte Gulf , Beast of Blood , Mad Doctor of Blood Island , among others . Rating : 5/10 . Passable and acceptable . The movie will appeal to adventure fans.
