In the film, Captain Jack Sparrow (Johnny Depp) finds himself on an unexpected journey to the fabled Fountain of Youth when he meets a friendly mermaid (Astrid Berges-Frisbey) and is tempted by a wicked former flame (Penélope Cruz) and her sadistic father, Blackbeard (Ian McShane).
Pirates of the Caribbean: On Stranger Tides was shot entirely in 3-D, and has a new cast of characters, but Captain Jack has not changed:
"Captain Jack is about as fully realized a human as he can be," Johnny Depp says with a laugh. "He's there. He's going to stay there. Which is fine."
"What's most interesting about Pirates 4 is you don't have to connect the dots for these subplots and sub-characters," Depp says. "It felt like a fresh, clean slate."
The first movie trailer will premiere Monday December 13.
