She has also stolen (sigh) his heart, as Will (Orlando Bloom) grows up to be a stalwart blacksmith - and more than able swordsman - who nurtures a secret crush on her. Knightley is Elizabeth Swann, owner of a medallion that gets the plot going a scant hour into ''Pirates.'' This trinket is first seen in a prologue sequence, in which little Elizabeth steals it from an equally young Will Turner. Her physical assurance suggests what Nicole Kidman might be like if she didn't spend so much time coughing tragically into handkerchiefs in an equally tragic pursuit of important roles. Verbinski's staging is as vertiginous as an amusement park ride and places the wiry and beauteous tomboy Keira Knightley at the center.

The movie is better than it deserves to be, given its origins: a ride at Disneyland and Disney World. The dazzling, high-flying silliness is quite an achievement. The director Gore Verbinski's penchant for logistics - combined with the producer Jerry Bruckheimer's desire to spend like a drunken pirate when it comes to putting everything on screen - melts into an often frenetic, colorful and entertaining comic adventure that often seems to be using ''Butch Cassidy and the Sundance Kid'' as a template. The action comedy ''Pirates of the Caribbean: Curse of the Black Pearl'' raises one of the most overlooked and important cinematic questions of our time: Can a movie maintain the dramatic integrity of a theme park ride?
