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. (00:22:25)
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. (00:50:20)
Revealing mistake: When the biggest "lost boy" curls into a ball and rolls down the gangplank scattering pirates, he was obviously a dummy. (01:48:10)
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. (01:46:30)Hamster
Revealing mistake: Near the end of the film, when Pan climbs over a snow-covered brick wall (and just before he re-acquaints himself with the dog in the dog house) the brick wall jiggles twice as he climbs over top, as though it was made of styrofoam. (02:06:05)
Revealing mistake: When the kids are having the big battle with the pirates on the ship, they have that gun that shoots out eggs. You can very easily tell that in one shot there is a fake rubber chicken in the basket on the top, and in the very next shot it is a big fat live chicken.
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 fairy dust over himself and flies out the nursery window. (02:09:20)Hamster
