Where Davis’ Morgan Adams is established as a tough pirate from the jump, Knightley’s Swann offers a more effective audience insertion persona as she begins the movie unable to handle adventure and soon progresses to being a resourceful but relatable heroine. By the third film in the series, Elizabeth Swann has double-crossed Jack Sparrow himself, saved the crew of the Black Pearl, and become a Pirate Lord, but this transformation required her to begin as a more grounded character much like the humble blacksmith’s apprentice, her love interest Will Turner. Cutthroat Island, in contrast, made its main character the unflappable swashbuckling hero, a seemingly smart choice that in practice sapped the movie's action of any tension as the audience were aware Morgan would survive no matter what (a mistake repeated by the later, Jack Sparrow-centric Pirates of the Caribbean installments).
