City Beneath the Sea is a 1953 American technicolor adventure film directed by Budd Boetticher and starring Robert Ryan, Mala Powers, Anthony Quinn and Suzan Ball. The film is based on the book Port Royal: The Ghost City Beneath the Sea by Harry E. Rieseberg.

Plot

In Jamaica, salvage divers Brad and Tony are hired by Dwight Trevor to find The Lady Luck, a ship that supposedly sank with all hands and $1,000,000 in gold bullion. There is no trace of the sunken ship, but there is a sunken city, the city of Port Royal that was destroyed in an earthquake in 1692. The gold bullion was actually lost in a modern-day quake and is part of an insurance fraud perpetrated by Trevor. He does not want the divers to find the gold and will stop at nothing to ensure the success of his plan.
