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 fighting Hook in front of the crocodile clock, he uses his sword tip to fling the pirate-hat and its wig attachment off of Hook's head and it flies over and lands on one of the Lost Boys heads. When it lands on his head it is wonky. But in the next shot it is sitting on his head perfectly straight and is then wonky again in the next shot.
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: Many times during the film when characters are flying, it is clear that they are flying on a harness due to their stiff, rigid movement and also due to the bulkiness that will suddenly appear on their back. It is especially noticeable at the end when Tootles sprinkles the faerie dust over himself and flies out the nursery window.
Continuity mistake: At the end of the movie when Peter crawls into Nana's doghouse to greet her (after returning from Neverland) he shakes the doghouse a little as he crawls in, causing snow to fall of its roof, which lands in the two dogbowls next to it. But in the next shot the dogbowls are now empty with no snow in them and also there is a long bone sticking out one of the bowls too.
