Quote - Wow, lots of little things Im sure everybody missed at that link....Barbosa's feet,  the branding iron,that matches Jacks brand on his arm from the first movie....neat.

Things I didn't miss:

The running gag with Jack's hat(s).

The animators' painstaking attention to detail, such as the way Jones' face tentacles wrap themselves around his hat brim to hold it in place against the rushing water when the Dutchman submerges.

Pay careful attention when the crew first visits voodoo queen Tia Dalma, particularly when Jack is "borrowing" some of her jewelry.  She and Davy Jones appear to have matching silver lockets.
