Rhys Williams is afforded the leading role in Columbia's Tyrant of the Sea. The film borrows a few pages from Jack London's The Sea Wolf by depicting Captain William Blake (Williams) as a power-hungry despot, who runs his ship like a private fiefdom. In contrast, Blake is a perfect gentleman on shore, especially when dealing with his pretty daughter Betsy (Valentine Perkins) and her various beaux. The story comes to a rousing climax during a pitched sea battle between English and French vessels, with Captain Blake not only contending with the enemy, but with a mutinous crew. Some of the action highlights have been culled from Columbia's stock-footage library, which did yeoman service for producer Sam Katzman.
