Continuity mistake: Moira throws the cell phone out the window with the antenna extended and the flap opened, and it is buried by Nana this way. When Peter finds it at the end of the movie however, the antenna is down and the flap is closed.
Continuity mistake: When Smee and Captain Hook are alone on the ship at night, Smee stands up just after eating chicken off his plate. His blue bandana hangs down his left shoulder near his plate. However, after a shot of Hook when it faces Smee again his bandana is now short, just resting on his left shoulder.
Continuity mistake: After finding his son hit a home run in the game with the pirates, Peter decides he must learn how to fly. The ball his son hit comes flying from the sky and hits Peter in the head, knocking him over. When he hits the ground, he is lying on grass, but one second later he opens his eyes on grey rock.
Continuity mistake: When Smee gives Hook his nightcap drink, Hook takes it in his hand and holds it at the top of the goblet so that it is hidden under his hand. But in the very next shot he is holding it by the handle and the whole goblet is now visible with a small black umbrella sticking out the top. Additionally, the position of the small umbrella that sits in the goblet changes a few times.
Revealing mistake: In the last scene that we see Maggie and Jack before they are kidnapped, when the bed covers fly off their beds, you can see that they are suspended by their corners. This is particularly obvious when they are lifted up. The middle of the quilt sags while the corners are lifted.
Continuity mistake: When Peter is carrying his children away from Hook's ship to leave Neverland, Hook starts running after him, threatening to always "leave daggers with notes bearing the name Hook" and then he stops at the top of the ramp. In the closeup he is waving his hooked hand as he shouts after Peter, but in the next shot he is waving his left hand forward, holding his sword outwards.
Revealing mistake: In one shot when a group of the Lost Boys are catapulted up into the air so that they can land on the side of Captain Hook's pirate ship, when they all hit the wooden pillared side it can clearly be seen to bounce as they land on it. It is possible to give some leeway on their weight making some effect - but not so much as to make the wood 'bounce' like it is made of soft material.
Continuity mistake: When Hook is sitting in his chair with the vanity tables at either side of him (with several mirrors on each table), we can see that there are two pots on each vanity table. Each pot has a small grey powder-ball sitting on top of it, which has red ribbons attached to it. During the scene the balls/ribbons differ in position and then at the very end of the scene (when Hook begins laughing at his plan to make Jack and Maggie love him) both of the grey powder balls have vanished.
Continuity mistake: When Jack and Maggie are in the large rope net that is hanging from the mast of Hook's ship, they are reaching out of the net trying to grab for their Dad's hands. In one shot Maggie is reaching both of her arms out of the net but in the immediate overhead shot she is only stretching one arm out.
Revealing mistake: When Tinkerbell is waking up all the Lost Boys and announcing Peter Pan's return, we see a shot in which Tink flies around a curly-headed boy. When she does, you can see the wire used to move the figure around his head. It is most visible when the boy turns his head toward the right side of the screen.
Continuity mistake: Before the big battle scene at the end, between the Lost Boys and the pirates, Peter shows up with a lot of makeup, mainly mascara and shadow on his eyelids. His extra makeup appears and disappears throughout the whole scene.
