Men steal for it. Nations go to war for it. The it is oil - and it grows on trees. Coconut oil is the precious lifeblood of 1870s South Seas traders. And lots of real blood will be spilled to get it! Screen royalty Burt Lancaster ist His Majesty O'Keefe in this last of three adventures that (along with The Flame and the Arrow and The Crimson Pirate) blew a revitalizing wind into the sails of the swashbucker genre. Action, cunning and derring-do are watchwords of the title seafarer as he befriends, defends and ultimately rules the islanders of exotic Yap. Lensed on gorgeus Fiji locations, grandly scored by Robert Farnon and rousingly directed by Byron Haskin, His Majesty O'Keefe delivers heroics of regal proportions.
