A motley group of folks go to a remote tropical island in search of a fortune in pearls. The group encounters an ancient tribe of primitive people who need a male from the group to mate with beautiful blonde Syrene (the extremely fetching Leigh Christian, who spends the entire film cavorting about in a skimpy bikini) in order to preserve their bloodline. Director Eddie Romero keeps the enjoyable story moving along at a snappy pace, maintains an engaging breezy tone throughout, and stages the exciting last reel action with rip-roaring aplomb. The solid cast of reliable B-pic regulars helps a lot: Patrick Wayne as nice guy diver Vic Mathias, John Ashley as two-bit conniving con man Logan, Lenore Stevens as foxy scientist Kathy Vernon, George Nader as imposing ruler Nereus, and Vic Diaz as amiable fisherman Manuel. However, Sid Haig easily steals the show with his delightfully energetic portrayal of smooth pimp East Eddie. Justo Paulino's bright cinematography provides an attractive sparkling look and boasts lots of impressive underwater photography. The inbred natives with their googly Ping-Pong ball eyes are a real goofy sight to behold. Entertaining drive-in fare.

Turkey of a film. A Filipino fantasy film about the quest for pearls on a secret island where a bunch of bug eyed islanders (when you see them you'll start laughing and want to turn it off) are ruled by a beautiful blond who looks normal.The cast includes Patrick Wayne and Sid Haig and is so silly and stupid that its almost enjoyable.Almost.Its a trash film that you'll either love of hate. I'm going to bet on hate, which is a shame since the cast is good and the crew behind the camera is responsible for the Blood Island films as well as many other good exploitation films. If you get a chance to see this, take a pass, there are better films out there.3 out of 10

This was a very enjoyable film, combination of horror, action, plot and some comedy. Sid Haig was very memorable as East Eddie. Had some of the better lines to deliver. John Ashley made the transition from teen star to producer and Patrick Wayne was the perfect choice for the square-jawed hero. Leigh Christian was ....hmmmmm... and the final film appearance of George Nader...too bad the other entries "Womanhunt","Beast Of The Yellow Night",and "Black Mamba" couldn't put together the same formula.

Manuel, (The last Vic Diaz) is a fisherman who wants to trade in his pearls for cash. He goes to a pimp named Fast Eddie (Sid Haig) and gets 500 pesos in return. Fast Eddie, sees a fortune in the pearls and decides to get some men together to get some more of the pearls. He takes with him, Logan, a scuba driver, Vic (Patrick Wayne, John Wayne's son) and lady Doctor.Fast Eddie and his crew beat up Manuel to find out where he got the pearls. He tells them that he got them from a lady as payment for taking her to an island. Fast Eddie and his crew go to the island and find tribe of people that appear to be half fish half human. They have weird raised eyeballs that look like ping-pong balls with black dots painted on them. They are led by a name, Neraus and his beautiful daughter who runs around the whole film in a skimpy bikini.Neraus orders his daughter mate with one of the people who have come to the island for the pearls, as it's vital to the tribe. She helps Eddie and his crew find pearls, but so she can keep them long enough on the island so she can mate.Beyond Atlantis is a very fun film as its 100% pure cheese. I laughed a lot and had a good time watching it. I'm a huge fan of Sid Haig, the actor who has made tons of great drive-in fare. It's always fun to see him. This film is only for fans of trashy campy films. Others beware.
