The good news is that I can provide you with some information about the 2005 movie "Pirates of the Caribbean: The Curse of the Black Pearl" and its Telugu dubbed version.
"Pirates of the Caribbean: The Curse of the Black Pearl" is a 2003 American fantasy swashbuckler film directed by Gore Verbinski. The movie stars Johnny Depp as Captain Jack Sparrow, Orlando Bloom as Will Turner, and Keira Knightley as Elizabeth Swann.
The curse was placed on the ship and its crew by Aztec gold, which was stolen by Captain Barbossa (played by Geoffrey Rush) and his crew. The curse turns the pirates into undead skeletons, and they can only be human again if the gold is returned.
