Believe me, there is. Almost every film (Pirates or not) has alternate dialogue - if not have completely different dialogue altogether! An interesting note I forgot to make in the blog, the title seen in late production draft of P3 was titled Pirates of the Caribbean: Calypso's Fury .

According to Terry's introduction:
 * You'll notice a different title, Calypso's Fury. This title was never in serious contention, simply a working title, until marketing deadlines forced the eventual title to be determined.
