Nearly every element of the previous two movies resurfaces in this third adventure, which ends up overloaded with characters and subplots. Returning villains Geoffrey Rush, Bill Nighy, and Tom Hollander team with Chow Yun-fat and a half-dozen pirate lords to bedevil fey buccaneer Jack Sparrow (Johnny Depp) and star-crossed lovers Orlando Bloom and Keira Knightley. Depp plays multiple versions of Sparrow, who now suffers from a split personality; his shtick is funny, but the players are all upstaged by the astonishing special effects, superior to those of earlier installments in creating a wondrous and menacing world. Gore Verbinski directed; with Naomie Harris, Stellan Skarsgard, and Keith Richards. PG-13, 170 min.
