PJ went ahead and changed the ending. From a review on Fandango:
"Jackson and co-writers Philippa Boyens and Fran Walsh make noteworthy departures from Tolkien, including such crucial moments as what happens when Frodo is finally standing on a ledge over the Crack of Doom inside the volcano where the ring must be destroyed, and how Aragorn makes use of the Army of the Dead that only he can command. Whole swaths of the book have been condensed and eliminated, but Jackson and company usually realize splendidly whatever they take on."
Blah.
