According to a company press release, Pirates of the Caribbean: On Stranger Tides will debut on May 7, 2011 at Disneyland.  

In what promises to be the 3D event of the season, Disney and XPAND 3D today announced a collaboration to show the World Premiere of Walt Disney Pictures and Jerry Bruckheimer Films’ Pirates of the Caribbean: On Stranger Tides at Disneyland on the evening of May 7th. The film, produced by Jerry Bruckheimer, directed by Rob Marshall and starring Johnny Depp, Penelope Cruz and Ian McShane at the head of a star-studded cast, will debut at a charity screening for the Boys & Girls Club of America in eye-popping active 3D by way of XPAND 3D’s new INFINITY Large Screen System.

Pirates of the Caribbean: On Stranger Tides captures all the fun, adventure and humor that ignited the franchise as Johnny Depp returns to his role of Captain Jack Sparrow in an action-packed adventure. When Jack crosses paths with a woman of 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 whom to fear more: Blackbeard or Angelica, with whom he shares a mysterious past.
