As of my last update in October 2023, there is no confirmed cast for "Pirates of the Caribbean 6," including the role of Jack Sparrow. Johnny Depp, who famously portrayed Captain Jack Sparrow in the previous films, has been involved in legal battles and controversies that have affected his career. While there have been discussions about the franchise's future, including potential new characters and storylines, no official announcements regarding casting have been made. Keep an eye on news sources for the latest updates.

Yes, there is a "Pirates of the Caribbean 4," titled "Pirates of the Caribbean: On Stranger Tides." Released in 2011, it is the fourth installment in the franchise, following Captain Jack Sparrow as he searches for the Fountain of Youth. The film introduces new characters, including Angelica, played by Penélope Cruz, and features returning characters like Captain Barbossa, portrayed by Geoffrey Rush. It diverges from the original trilogy's storyline, focusing on a standalone adventure.

In "Pirates of the Caribbean: On Stranger Tides," the fourth installment of the series, Will Turner (played by Orlando Bloom) and Elizabeth Swann (played by Keira Knightley) do not appear because the story shifts focus to Captain Jack Sparrow's new adventure and introduces new characters, such as Angelica (Penélope Cruz). The filmmakers decided to take the narrative in a different direction, allowing for fresh storylines without the central couple from the previous films. Their absence reflects this change in focus rather than any specific storyline involving them.
