As Universal Pictures would not spend extra money to make a Bud Abbott and Lou Costello picture in color, the duo opted to do it themselves. Using a contractual agreement with Universal that permitted them to make one independent film per year, they made this film using Abbott's company, Woodley Productions. The Technicolor process was too expensive, so they opted for the less costly SuperCinecolor.
Although Hillary Brooke plays Anne Bonny with an English accent (even though Brooke is American, not English), the real Anne Bonny was Irish (born Anne Cormac). Bonny's name is usually spelled without an "e," but sometimes--as in this film--it is spelled with the "e".
Charles Laughton had wanted to do a knockabout physical comedy for some time, but could never find anything appropriate. He had long been an admirer of Lou Costello's abilities as a slapstick comedian, and--as he remarked some time later--he decided "If you want to learn something, learn it from the best" so he let Costello and Bud Abbott know that he was interested in doing something with them. This picture is the result.
