 During the swordfight in the caves at the Isla del Muerta, there is  additional dialogue with Jack and Barbossa. Seconds after the swordfight  begins, Barbossa says, "Damn it, Jack! I was almost liking you!" and Jack  sweetly replies, "I know," and the swordfight continues. This is featured on  Disk 2 of the DVD, but not as a deleted/extended scene.
