Captain Jack Sparrow Faces New Dangers in Pirates of the Caribbean: On Stranger Tides

Walt Disney Pictures just released the first trailer for Capt. Jack's fourth adventure, "Pirates of the Caribbean: On Stranger Tides." And while several of the elements that made the original three films one of the top five trilogies of all time, much has changed.
The movie is due to be released in 3D and in IMAX on May 20, 2010
Johnny Depp is back, of course, as Jack, along with Geoffrey Rush as his old nemesis, Barbossa, and Kevin R. McNally as his first mate, Gibbs. But Orlando Bloom and Keira Knightley do not appear in this installment. Instead, Jack confronts new threats, including a legendary pirate, and a woman from his past that reignites and old flame. Jack will have to face them all as he pursues the ultimate hidden treasure: finding the Fountain of Youth.
