Deliberate mistake: Keira's stunt double Sonia is obvious in different shots throughout the film. When Elizabeth walks onto the deck of the Pearl, only to see the skeletal pirates, she stumbles backward and lands on the tarp, and it's very apparent that the one who comes back down from mid-air onto the tarp and goes back up is Sonia. Later on Isla de Muerta, Elizabeth whacks Jacoby (burning beard) with the gold rod and soon after she approaches a second pirate. This pirate is very pleased with himself when he takes the gold bowl off his head, and we can then see it is Sonia actually whacking him, but in the very next shot it is Keira reacting to whacking the guy.
