So locations wouldn't have to be revisited by the crew, some scenes were filmed during the filming of Pirates of the Caribbean: Dead Man's Chest (2006).

They started filming without a finished script.

Keith Richards has agreed to appear in a cameo as Jack Sparrow's father. He has been pursued for a cameo appearance since the first installment of the series.

The crew built a sixty foot replica of the front half of the Black Pearl on the back of a semi trailer in the salt flats of Utah for a shoot with the Shadow of the Pearl. The shoot was scheduled for 19 days, it took 4.

The cast and crew filmed off of the coast of Southern California in the South Bay Area around the last week of August 2006. The Black Pearl could be seen sailing to and from port from the Palos Verdes Estates and Redondo Beach pier. The stars of the film would take time off from shooting to meet fans and sign autographs.

The first cut of the film was over 3 hours long.

Called by the crew "Pirates 3".

The series has a rather inconsistent naming concept in Germany: The first film was named "Fluch der Karibik" (lit. "Caribbean's Curse"), the second "Pirates of the Carribean - Fluch der Karibik" (although early posters showed the more literal "Fluch der Karibik - Die Truhe des Todes") and this one "Pirates of the Carribean - Am Ende der Welt".
