Pirates of the Caribbean: At World's EndThe first Pirates of the Caribbean was long and sometimes tedious but it had the advantage of being funny - at least when Captain Jack Sparrow was waving his arms and stumbling around like a drunken sailor, which indeed, he was.Johnny Depp's characterisation of the pirate as rock star, basing his performance on the shipwrecked grandeur of Keith Richards, was inspired and beguiling. Keira Knightley and Orlando Bloom added a delicate upper-crust English beauty to balance the scales and form a love triangle. In order to have fights, they needed someone to hold the other sword and that was Geoffrey Rush, as Captain Barbossa, the ghost with the worst dental hygiene on the Spanish Main (but the biggest hat).When the dialogue reached an exhausted impasse - and that was often - Barbossa and his band of scurvy cut-throat ghosts would steal the ship, start a fight, strand somebody on an island or, if necessary, turn upon each other. Director Gore Verbinski kept this up for 143 minutes, some kind of bum-numbing record for a comedy.The huge success of the first movie meant that the second and third sequel were shot back to back. Producer Jerry Bruckheimer saved millions in sets and staff and was able to get both movies out just 10 months apart. Given that Dead Man's Chest made twice as much money as the original, he's hoping that At World's End will bring home a third mountain of treasure.It will make a squillion but the truth is it's not very good. The faults of the first movie are still there, only more so, and it doesn't have the benefit of being fresh. At 168 minutes, it's also longer than either of its brothers, which is just ridiculous. Never mind the quality, feel the length. Worse still, the plot is incoherent and half the movie seems to be taken up with static scenes where the characters try to explain it or complicate it with yet another revelation. It's really a continuation of the second film, rather than a new movie, so if you missed Dead Man's Chest it's even harder to follow.
