Continuity mistake: When Jack is on the Black Pearl in Davy Jones' Locker, the are scratches on his right hand. But a few minutes later when Barbossa leads the crew to Jack's rescue, the scratches are gone.
Continuity mistake: At the end, when Jack says, "Drink up me hearties, yo ho," the compass rope flips its direction, from hanging across his palm to over the back of his hand, between shots, including the compass close-ups.
Continuity mistake: At the mass hanging, when the singing begins, in one shot of the people (with the boy) standing at the gallows, the others down below, who wait at the head of the line, are also seen behind them singing. In a following shot, some at the head of the line differ.
Continuity mistake: On the island with the contaminated water, when Pintel rolls over the dead body in the wideshot, his left hand is under the body's arm gripping the body, but when it cuts to a close-up, Pintel's left hand grips the body's arm.
Continuity mistake: The shape of Will's long scar is entirely different, between the time he commands the Dutchman to when he leaves Elizabeth after their day together.
Revealing mistake: Throughout the movie, the edges of Barbosa's yellow contacts are easily visible (especially in the scene where he orders Calypso to the brig).
Continuity mistake: At the meeting of the brethren, when Barbossa stands on the table and fires his pistol, the height of the left and right cannonballs he holds differs between shots (the difference between each other, not to the table).
Revealing mistake: At the beginning of the film, when Sao Feng is introduced, a couple of his real nails are visible under the fake long dirty ones glued atop them. It's most noticeable when he scratches his head.
Other mistake: Near the end of the movie, an order is given to fire a cannon shot at the masts of the Pearl and the Dutchman as they have become entangled. We then see a mast being destroyed by the shot but when the ships separate, not one of them has a broken mast.
Continuity mistake: Aboard the Pearl, after Elizabeth asks, "What shall we die for?" and begins a rousing speech to the crew, her hairstyle differs significantly in following shots (despite the wind).
Other mistake: In numerous shots modern bobbypins (the white kind brides wear on their headdress) are clearly visible inside the curls of the men's white wigs. For instance, they can be seen when Norrington is reunited with his sword; later when he dies; when Beckett talks about the immaterial becoming immaterial; finally, when he says, "It's just good business," as the Pearl and Dutchman fire on Endeavor. The type of 'hair pin' seen in the wig curls did not exist in the mid 18th century.
Revealing mistake: Just after Barbossa and Elizabeth reach Sao Feng's residence, down below when Gibbs pulls the bars they actually bend.
Continuity mistake: When Davy Jones is talking to Calypso/Tia Dalma in the brig, her mascara runs because of her tears. In the next shot, the streaks are gone and it's perfect again.
Continuity mistake: When Sao Feng is first introduced he has a red scarf tied round his pinky, and the way it is knotted differs between the following shots.
Continuity mistake: In the Locker, before Governor Swann says, "Elizabeth? Are you dead?" in his close-up Elizabeth is seen in the background crossing the broken rail beside Jack, but two shots later she crosses that part of the rail again as she shouts to her father.
Continuity mistake: Elizabeth has a beauty mark above the corner of her right eyebrow which actually disappears in some of her close-ups. For instance, when she is with Norrington and asks, "Know what? Which side you chose?" and later, when he kisses her. Later, in the scene with her son, the beauty mark is gone in one close-up and then just reappears in the next one, as she glances at her son.
Continuity mistake: After the Pearl makes an interesting return to the Locker's shore, Jack walks toward everyone on the beach, leaving a trail in the sand behind him. As Jack speaks to them in one wideshot, his trail in the sand near the long boat disappears (not due to the water).
Continuity mistake: In Singapore, Ragetti looks up through the floor boards and acts like he sees Elizabeth, but when you see his eye through the crack in the floor, it's the brown wooden which he cannot see with (his other eye is blue).
Continuity mistake: When Johnny Depp's sitting next to the goat and it turns its head to face him, he goat's body is turned to the right, but when we see a closeup shot of it its body is now turned to its left.
Continuity mistake: The scar on Sao Feng's left side moves around between the shots, mostly up and down.
Answer: From the point of view of the Dutchman, Bootstrap is dead enough to serve on the ship. The idea is that Jones rescues people who would otherwise simply have drowned and makes them serve on his ship in lieu of death; as such, they can be considered technically deceased. Elizabeth has been into the Locker, yes, but with the demise of Jones, the Locker may not even exist any more. Will's task is to escort the dead into the afterlife, not the Locker - while Elizabeth survived the Locker, the afterlife may be something entirely different. The rules regarding the Dutchman and the duties of her crew are never spelled out, but it seems that, no, Elizabeth cannot live on her.
