Continuity mistake: In the hallway Peter struggles with his shadow and while sitting on the dresser the large fan picture hanging above the dresser falls down onto the dresser top as a result. Peter still sits there and after Peter yells, "I've got you now!" there is a close-up of the dresser as Peter falls off and the back is seen but the large picture is missing. It couldn't fall forward as Peter blocks it when he sits there and it couldn't fall behind the dresser because the back has a lip on it. In all of the subsequent shots of the dresser and the floor the picture is not seen, it simply vanished. (00:13:30)
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: When Peter tries to attach his shadow the toys, loose books and stacked books at Wendy's footboard differ in the following shots. Wendy exclaims, "You can fly!" and the books in the wardrobe are also seen and when she climbs out of bed the books in the wardrobe differ as well. Throughout this scene in subsequent shots these things differ, with no one touching them. (00:14:50)
Continuity mistake: Unable to make his shadow stick Peter is upset and when Wendy surprises him he zooms up to the ceiling and bangs his head. In this shot the light fixture hangs flush with the ceiling under a decorative medallion around the base. Later, when Peter floats to the ceiling after John says, "You offend reason sir" the fixture now hangs way down on a very long chain. (00:15:00 - 00:21:15)
Continuity mistake: Throughout the whole scene in the nursery when Wendy and Peter are talking, Peter's hair is constantly changing. ie: position of bangs on forehead. (00:15:00 - 00:22:55)
Continuity mistake: The distance between Nana's doghouse and Wendy's nightstand changes. For example, when Tinker Bell flies into the nursery she flies into Nana's house and we see the distance between the two. When Wendy climbs out of bed and curtsies to Peter the two are nearer to one another, and when she says her full name the two are even closer, but when Tink pulls Wendy's hair the house and nightstand are further apart again. (00:15:20 - 00:19:55)
Continuity mistake: The dirty smudges all over Peter's body either disappear altogether or change shape, position and/or shade in consecutive shots. For example, the smudges at Peter's left ear or just under his neck change while in the Darling nursery. (00:15:35)
Continuity mistake: Wendy gets a needle and thread, then shows Peter the needle. As she says, "This may hurt a little," she shows the sharp needle to him. When she does the light in the room becomes brighter at this point (not a deliberate pun) as compared to the dimly lit nursery until this moment. It stays brightly lit until they leave for Neverland. (00:16:05)
Continuity mistake: After Wendy sews the shadow onto Peter the light in the nursery brightens. The items in the room cast their own shadows, for example, the clock and light fixture over Michael's beds. These shadows change drastically in the following shots, until they fly off to Neverland. (00:16:45)
Continuity mistake: After Wendy says, "I should like to give you a kiss," and proceeds to give Peter the thimble, it is only now that Peter's 'kiss' for Wendy is on the garment he is wearing. It is not on his garment in all the previous shots of Peter. (00:17:50)
Continuity mistake: Peter kicks the jack-in-the-box and it falls over, but when Wendy starts to say, "But there's no such thing as," Peter flies toward her and the jack-in-the-box is upright now. (00:18:55)
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: As Peter hushes Wendy and explains, "...I shall never find her if she's dead," Wendy's bed is seen beside them. When Peter grabs hold of Tink and tosses her at Wendy's pillow, Wendy's blankets are positioned quite differently than the previous shot of it. (00:19:05 - 00:20:05)
Continuity mistake: There are two dolls perched on either side of Wendy's headboard in the nursery. When Tink grabs hold of Wendy's hair, pulls her back towards the bed and slams her into the footboard, the doll on the left falls, yet the doll is back up on the headboard in the following shots. While Peter speaks with Wendy throughout these shots the positions of both of the dolls change. (00:19:55)
Continuity mistake: The toy house is placed up against the wall near the children's bedroom door on the wood floor, with its front door facing out towards the boys' beds. However, when John flies and promptly falls, the house is not only placed away from the wall and on the rug, it is also facing the opposite way, with its front door facing the children's bedroom wall. (00:19:55 - 00:21:45)
Continuity mistake: Before Peter takes the Darling children to Neverland, just after he says, "We'll ride the winds back and away we'll go," Wendy backs up between the two beds of her brothers asking if they can come too. Michael (the younger one on the right) is seen lying on his back in the middle of the bed with his arm over his chest, but in the next close up of him, he is lying on his side hanging over the edge of the bed. (00:20:40)
Continuity mistake: When Peter floats up after John says, "You offend reason sir," the clothes wardrobe is seen behind Peter and there are three very large floral hat boxes sitting on top. Yet when Michael flies and lands on top of that wardrobe the floral boxes are arranged completely differently. (00:21:10 - 00:22:05)
Continuity mistake: When John says, "You offend reason sir," Peter floats up. The large light fixture is hanging from the ceiling. However, in the next shot facing Peter when he says, "Just think happy thoughts," where is the light fixture? It's gone so Peter can fly around the ceiling, but it's back again in later shots. (00:21:15)
Continuity mistake: When John wants to learn to fly, he flings back the covers on his bed. When he goes back on the bed to 'take off', the bed is made. (00:21:20)
Revealing mistake: When Peter says "Just think happy thoughts, and they lift you into the air" he does a sort of twirl, at the beginning stage of his twirl you see the border at the top of the wall which makes the room seem way too small for him to do what he did. (00:21:20)
