Pirates of Tortuga is a 1961 American swashbuckler film which invented an alternate history for the actual Welsh privateer Henry Morgan.

[2] In the 17th century, a Welsh captain (Ken Scott) and his crew are dispatched to the Spanish-controlled island of Tortuga, where famed privateer Henry Morgan (Robert Stephens) has defected from his support of the English empire and is running a strictly piratical venture, stopping any and all vessels, including British carriers.

A young woman (Leticia Roman) inadvertently stows away on the captain's vessel and becomes the de facto central focus of the story (Morgan doesn't appear until the latter half of the film).

She is initially taken to the nearby island of Jamaica, where she briefly makes a play for the colonial governor, but eventually sets her sights on the captain himself.

The film was shot entirely on the Fox backlot in Los Angeles, using the water tank that had been created for the TV series Adventures in Paradise.
