The Bermuda Depths is an obscure 1970s horror movie that manages to combine Giant Monsters and Supernatural Romance. It was coproduced by Rankin Bass and Tsuburaya Productions. A drifter named Magnus returns to his home in Bermuda (which he left after his father was mysteriously killed years before) and is reunited with Eric, an old friend who is learning about marine biology from an old scientist named Dr. Paulus. They end up investigating evidence of a giant turtle inhabiting the local waters.
