IGN (with a tip of the cap to ComingSoon) have released this absolutely fantastic new concept art for the new Disney / Jerry Bruckheimer movie, Pirates of the Caribbean: On Stranger Tides.

These new images give us a great look at a ship used in the movie along with a dark looking shot of Ian McShane and an old looking shot of Geoffrey Rush.

Synopsis:  Produced by Jerry Bruckheimer and directed by Rob Marshall, “Pirates of the Caribbean: On Stranger Tides” captures the fun, adventure and humor that ignited the hit franchise—this time in Disney Digital 3D™. Johnny Depp returns to his iconic role of Captain Jack Sparrow in an action-packed tale of truth, betrayal, youth and demise.  When Jack crosses paths with a woman from his past (Penelope Cruz), he’s not sure if it’s love—or if she’s a ruthless con artist who’s using him to find the fabled Fountain of Youth. When she forces him aboard the Queen Anne’s Revenge, the ship of the formidable pirate Blackbeard (Ian McShane), Jack finds himself on an unexpected adventure in which he doesn’t know who to fear more:  Blackbeard or the woman from his past.

The international cast includes franchise vets Geoffrey Rush as the vengeful Captain Hector Barbossa, and Kevin R. McNally as Captain Jack’s longtime comrade Joshamee Gibbs, plus Sam Claflin as a stalwart missionary and Astrid Berges-Frisbey as a mysterious mermaid.

Captain Jack Sparrow (Johnny Depp) finds himself on an unexpected journey to the fabled Fountain of Youth when a woman from his past (Penelope Cruz) forces him aboard the Queen Anne’s Revenge, the ship of the formidable pirate Blackbeard (Ian McShane).

Pirates of the Caribbean: On Stranger Tides is released May 18th 2011, and is directed by Rob Marshall.
