Audio problem: Aunt Millicent checks on the sleeping children and in the shot outside the bedroom we hear the sound of her closing the door. However when she is startled by her true shadow we see the bedroom door has been left ajar. (00:14:30)
Continuity mistake: In the battle scene on the ship, Hook throws Peter's sword into the air and Peter catches it with his left hand, but in the next shot a second later it is in his right. (01:25:00)
Continuity mistake: When Wendy, Michael and John return to the nursery, Michael kneels down in front of Nana. In the next wide shot, the bear, etc., on Michael's back differs, as well as Nana's position on the floor. (01:35:05)
Continuity mistake: When the mermaids swim toward Peter and Wendy, in the wide shot as three of them begin to surface, floral plants float between two of the mermaids. However in the close-up as the mermaids surface, they are next to one another with no plants between them. (00:42:20)
Continuity mistake: When John tries to fly for the first time, he jumps off the bed and we see him soar across the room, but the room is nowhere near long enough for him to have gone as far as he did before he crashed. (00:21:30)
Audio problem: Wendy is tied to the mast on the Jolly Roger when Hook forces her to tell a story. In the wide shot, the pirates start to find seats and Hook has his hand at Wendy's throat as we hear her begin, "There was a boy named Peter Pan," yet her mouth does not move. She continues to say off camera, "who decided not to grow up," and in the next shot Hook gets angry and tells her to skip the prologue. (01:18:00)
Revealing mistake: At the bank, as Nana, Wendy and the letter carrier all skid towards Mr. Darling and the other bankers, in the overhead shot it is not Jason Isaacs (Mr. Darling) standing at the front of the bankers. The hairline is completely different, as he has a prominent receding hairline on both sides of his head which is seen in many shots. (00:09:25)
Continuity mistake: In the beginning when John and Michael are explaining Hook to Aunt Millicent, Michael's hair is at first neatly parted, but then it becomes messy and then back to neatly parted. (00:03:45)
Continuity mistake: The position and characteristics of the cut on Peter's forehead change from the time Hook slices Peter with his hook, as they fly over the Jolly Roger, to many of the subsequent shots. The two trails of blood change drastically as well. (01:26:50 - 01:32:20)
Continuity mistake: When Mrs. Darling rushes back to the nursery, realizing that her children are home, she stands at the doorway facing Wendy, John and Michael and the blankets on Wendy's bed are very messy. However, when she hugs the children the blankets on the bed are spread quite neatly. (01:36:20)
Continuity mistake: In Hook's stateroom, he speaks with Wendy, dries her tears and moves some of her hair behind her shoulder. Her hair changes position in the following shots. Throughout the film Wendy's long hair changes position in many consecutive shots. (01:02:10)
Continuity mistake: When Smee places the pocket watch down on Hook's desk, in the close-up Hook smashes it twice and pieces of glass, metal, etc. go flying everywhere. Yet in the next front shot the loose parts are positioned differently when Hook is about to smash it a third time. (00:27:55)
Continuity mistake: As Michael points a sword at Smee on the Jolly Roger, in the close-up Smee hangs the jewels on Michael's sword and takes both guns out and shakes them around. Then in the side shot the jewels hang differently and he takes both guns out again. (01:24:45)
Continuity mistake: Tink unlocks the nursery window, flies about and darts under John's bed. In the view from above John's bed, we see a large play castle at the brass footboard of his bed. However, in the next shot looking out from under his bed as Tink opens the wardrobe, we see through the bars of the footboard that the play castle is GONE. Then in the next shot of the bed the castle is back. (00:12:25)
Continuity mistake: In the scene where Peter ducks down next to the Lost Boys, we see Hook look at the boys and Peter is in the far right, but as Hook comes closer, Peter is now in the middle (it would have been impossible for him to slide into the middle because Hook would have noticed it). (01:22:45)
Revealing mistake: After Peter watches the Darlings and the Lost Boys through the nursery window, he begins to fly off. The camera pans onto the rug to show Peter's exiting shadow on the long bright spot of light coming through the window, which Wendy notices. This lit area on the rug is much larger and brighter than in the previous or following shots. (01:41:35)
Continuity mistake: As Wendy, John and Michael float at the ceiling, Wendy asks, "Oh! What about mother?" and the hat boxes are visible on the wardrobe, with the square on the left. Yet, when they all exclaim, "Pirates!" the round hat box is now on the left. (00:22:35)
Continuity mistake: When Peter flies through the nursery and stops at the drawer with his trapped shadow, the door to the nursery remains wide open behind him. Yet, when Aunt Millicent checks on the children she, both visually and audibly, opens the bedroom door. (00:13:10 - 00:14:15)
Continuity mistake: When Wendy is tied up aboard the Jolly Roger the amount and/or position of rope around her differs greatly between shots. For example, when Hook shoots Noodler it's wound around 6 times - on her left it's 3 over the wood and 3 under, yet when Hook cuts the lines it's wound 5 times - on her left it's 4 over the wood and 1 under. (01:18:20 - 01:19:20)
Continuity mistake: Tinker flies into the nursery, zips around the room and in the shot from under John's bed goes to the wardrobe with the hanging clothes. Then in the close-up she plunges into all the readily available pockets. These clothes which are seen in many following shots too are quite different in the later shots, not to mention the significant difference of the close-up with all the pockets in perfect position for Tinker Bell to fly in and out of. (00:12:30 - 00:15:20)
Answer: It's not that you never age, it's that you never grow up, i.e. pass into puberty and become an adult.
