John Payne stars as legendary pirate Barbarossa -- aka Redbeard -- in Raiders of the Seven Seas. Capturing a Spanish galleon almost single-handedly, Barbarossa claims haughty Contessa Alida (Donna Reed) as his own property. Engaged to marry naval officer Alfredo (Gerald Mohr), Alida despises Barbarossa, but she changes her mind when she finds out what a louse Alfredo can be. All loose plot strands are neatly tied up during the swashbuckling finale, wherein Barbarossa leads an attack on Havana. The supporting cast of Raiders of the Seven Seas is populated with such familiar faces as Lon Chaney Jr., Henry Brandon, and Frank DeKova.
