Peter Boyle’s portrayal of the theatrical yet unpleasant "Lord Durant" truly dominates the film, beginning with a deliberately over-the-top bathing scene reminiscent of Cleopatra and establishing the tone for what follows: a silly, though briskly paced story. The aristocratic "Debrett," played by James Earl Jones, and pirate "Ned Lynch," portrayed by Robert Shaw, become fed up with this governor’s harsh rule and decide to remove him from power. This leads to a sequence of amusing incidents, with "Maj. Folly" (Beau Bridges) trying to stop their efforts while Geneviève Bujold as "Jane" contributes some visual appeal. The movie is chaotic, certainly. Shaw seems to have studied Errol Flynn’s “Janet & John” and may have indulged in a bit too much alcohol before filming. James Earl Jones delivers a performance about as flexible as one of his own vessels, and Bujold simply doesn't have enough screen time to make any significant impression. Anjelica Huston also appears briefly, but her role feels similarly insignificant. Despite all this, it probably was fun to film, given the abundance of action sequences and acrobatics, and the ending is genuinely entertaining in its exaggerated style. It’s a film easily overlooked, yet still provides some enjoyment.
