The fan frenzy surrounding Pirates of the Caribbean: Dead Man’s Chest has reached such a fever pitch that had producer Jerry Bruckheimer merely shot two hours of Johnny Depp filling out his tax returns and released it under the Pirates moniker, it still would have scored a $75 million opening weekend without breaking a sweat. Yet at 145 minutes, Dead Man’s Chest ends up providing too much bang for the buck. That’s just about the same running time as its predecessor, but that film wore its length better. Certainly, those expecting amazing feats of derring-do won’t be disappointed by this new film. The effects-driven action scenes are clearly the picture’s highlights, and they alone make Dead Man’s Chest worth the price of admission. But on the heels of Superman Returns, a movie of substance that nevertheless made sure not to skimp on its adventure quota, this one too often rings hollow. The central thrust finds Captain Jack Sparrow (Depp) tangling with the ghostly Davy Jones (Bill Nighy) in an effort to save his own soul from eternal damnation beneath the sea’s surface; it’s possible that his scheme will require sacrificing his friends Will Turner (Orlando Bloom) and Elizabeth Swann (Keira Knightley), but that’s a compromise the self-serving Jack can accept. Depp’s still a lot of fun as the scurrilous Sparrow, but a headline-grabbing performance that seemed blazingly original the first time around no longer has the power to surprise. Bloom’s Will and Knightley’s Elizabeth are even less developed, and except for a couple of quips (him) and tirades (her), it’s hard to remember anything of substance that they do during the course of the film. Instead, it’s the makeup-sporting actors who steal this one, particularly Nighy as the ruthless Davy Jones and Stellan Skarsgard as Will’s spectral father, “Bootstrap” Turner.
