usually remain masked, and whether he is honorable or evil depends on the audience's perspective. This acts as part of Will Turner's arc, in which Sparrow tells him a pirate can be a good man, like his father. Following the success of The Curse of the Black Pearl, the challenge to creating a sequel was, according to Verbinski, "You don't want just the Jack Sparrow movie. It's like having a garlic milkshake. He's the spice and you need a lot of straight men ... Let's not give them too much Jack. It's like too much dessert or too much of a good thing." Although Dead Man's Chest was written to propel the trilogy's plot, Sparrow's state-of-mind as he is pursued by Davy Jones becomes increasingly edgy, and the writers concocted the cannibal sequence to show that he was in danger whether on land or at sea. Sparrow is perplexed over his attraction to Elizabeth Swann, and attempts to justify it throughout the film. At World's End was meant to return it tonally to a character piece. Sparrow, in particular, is tinged with madness after extended solitary confinement in Davy Jones's Locker, and now desires immortality. Sparrow struggles with what it takes to be a moral person, after his honest streak caused his doom in the second film. This is mainly shown by his increasingly erratic behaviour and Jack's hallucinations, which appeared to be simply his deranged mind in the beginning where dozens of "Jack Sparrows" appeared to crew the ship in his solitary exile, but later the hallucinations grew more important and there were mainly two "Jacks" constantly arguing about which path to follow: the immortality or the mortality. The last hallucination took place while Jack was imprisoned on the Dutchman, where his honest streak won. By the end of At World's End, Sparrow is sailing to the Fountain of Youth, an early concept for the second film.

If there ever were another Pirates of the Caribbean film, I would start fresh and focus on the further adventures of Captain Jack Sparrow." On Stranger Tides was first announced on September 28, 2008, during a Disney event at the Kodak Theatre. Verbinski did not
