The central plot device of Pirates of the Caribbean: The Curse of the Black Pearl is a cursed pirate treasure, but the protagonist, Jack Sparrow, may have incurred a curse from another source based in real nautical superstition pirates believed in. While the film-by-film stories of the Pirates of the Caribbean series tends to focus ostensibly on a rotating pair of romantic leads, the unfailingly off-kilter Jack Sparrow is the consistent character around whom most of the action revolves.

In a variant on classic pirate tales, The Curse of the Black Pearl details the return of stolen gold to break a curse of ghastly immortality put upon the mutinous crew of the Black Pearl. The ousted Captain Jack Sparrow wasn't party to the theft, so he isn't cursed by it until he tactically allows himself to be in his final fight with Hector Barbossa. However, Jack's history with the Pearl exposed him to a different supernatural danger.

There is an established nautical superstition that it is bad luck to rename a boat. The belief posits that a ship is catalogued by the gods under its first name, and changing it would be akin to hiding something from said gods, who would presumably become rather vengeful. Sparrow initially came by the Black Pearl first as a pirate ship under Captain Morgan, then later under his own command as a merchant vessel in the service of the East India Trading Company. In those days, it was still named the Wicked Wench, but he rechristened it the Black Pearl after Davy Jones saved it from being scuttled by Lord Cutler Beckett. Thereafter he was subject to all of the turmoil shown in the films, including his own (temporary) death — and while an argument could be made that most of the trouble was self-inflicted, it also certainly smacks of bad luck.

The blending of real-world history, mythical superstitions, and modern adventure tropes is a hallmark of the Pirates of the Caribbean series and the broader genre from which it borrows. An interesting twist arising from this fusion is that, while the original superstition warns that renaming a ship would upset the powers of the sea, it was in fact the legendary Davy Jones's resurrection of Jack's ship that inspired the change of moniker in the first place. Whether or not this means Jones was complicit in Jack's decision is left up to interpretation, but it does suggest that, in this particular instance, Jack's tempting of fate was enabled by powers greater than himself.

Of course, none of the films imply that any of their events are due to Jack's renaming of the Wicked Wench. The original name of the Black Pearl is not even mentioned on-screen, left instead to supplementary works. But the possibility of a connection and the nod to esoteric superstition add another layer of meaning that deepens the already textured worldbuilding of the Pirates of the Caribbean series.
