User blog comment:J Fan/POTC 3 & 4 scripts on Wordplay!/@comment-4693709-20140320003156/@comment-4693709-20140320234254

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 .

Well, that's indeed interesting! Although, I would have prefered if they would have post an older version of the script, so that we see how much it changed, like they did with CotBP.
