YANKEE BUCCANEER
"X" marks the spot where a U.S. commander (Jeff Chandler) must secretly infiltrate and stop a Caribbean colony of pirates and privateers before they send him plummeting to the depths of Davy Jones's locker.
The lady of this pirate flick is Suzan Ball, which was Lucille Ball's second cousin.
Sadly she died of cancer at the very young age of 21.
