Continuity mistake: We see the outside of the Darling's house as Wendy speaks of Alf Mason's ugliness, when she looks out from her window after Nana barks, when she searches the patio with a candle, when Nana is chained outside and when Peter, at a distance, sees the Darlings leave their home for the evening, etc. Among the changes, seen in certain shots, is the house adjacent to the Darling's home and the Darling's patio's appearance and surroundings. (00:01:10 - 00:11:55)
Continuity mistake: When Aunt Millicent is speaking with Mr. and Mrs. Darling about Wendy, she is holding a wine glass with engraved etchings. The position of the markings vary when the camera faces her and when the camera faces the Darlings. (00:05:45)
Continuity mistake: After the children return, the shadows cast within the room change drastically in the following shots. For example, when the wall behind John's and Michael's beds is visible the shadows cast by items, such as the clock and light fixture, are very different throughout this last scene. (01:36:25 - 01:37:55)
Continuity mistake: When the children arrive home, John does not have a mark on his forearm. As John shakes his father's hand there is a long black mark above his wrist. During the family hug while they kneel on the floor the mark is smudged. When John is on the floor with his father and the Lost Boys, Michael dumps the treasure onto the rug and in the next shot as John holds one of the twins the mark on his forearm is long and clear now. The mark changes position as well. (01:37:15 - 01:38:55)
Continuity mistake: Hook sneaks into Peter's hideout while Peter sleeps in order to kill him. In the first close-up Hook tries to reach Peter, who's lying down, as Peter mumbles in his sleep. In Peter's second close-up he is in a completely different position as the poison drops into the water. As he wakes with a start in his third close-up, Peter is lying in the same position as the first close-up. (01:10:45)
Continuity mistake: On the Jolly Roger, after Hook tells the others, "He's mine," and Peter shouts, "Now," we see Wendy bursting through a closed door and surprising the pirates. In the next shot we see Wendy bursting through the closed door again from another angle and her hair is different in both shots. (01:24:10)
Continuity mistake: When Wendy says, "But, there's no such thing," Peter flies to her and covers her mouth with his hand. When he says, "Don't say that." In this side shot his fingernails are relatively clean. In the next shot facing Wendy, Peter's hand is still on Wendy's mouth and his fingernails are filthy. Then back to the side shot and his fingernails are clean again. (00:19:00)
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)
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)
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)
Answer: It's not that you never age, it's that you never grow up, i.e. pass into puberty and become an adult.
