Continuity mistake: When Hook is telling Pan of Wendy leaving they look down at Wendy fighting with one hand on her hip and one holding the handle of the sword, the next shot in slow motion she is holding the handle with both hands. (01:26:25)
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: Peter and Hook are face to face as Hook taunts Peter saying, "I'm afraid the window's barred..." In the shots facing Hook, Peter holds the base of Hook's hook with his left hand while his right hand blocks Hook's hook with his sword. However in the shots facing Peter, while the boy blocks Hook's hook with his sword, Peter's left hand does not hold the base of Hook's hook. (01:26:50)
Continuity mistake: In the scene right after Pan has fallen, the same pirate grabs Wendy twice, once right after Hook takes Pan by the throat and once after he hits Pan on the head with his hook. (01:27:50)
Continuity mistake: When Wendy says, "But...this is yours.", Hook pulls her up by her arm onto her knees and her hair goes from being straight down over her right ear, to the next shot, when it is again tucked behind her ear as it appears throughout most of the film. (01:29:20)
Continuity mistake: During Wendy's farewell to Peter, when Hook pulls Wendy up she says, "Tis just a thimble," and right beside Wendy a pirate grasps John at the neck with his hand. In the next side shot as the pirates laugh, the pirate holds John around the shoulders with his arm, however, in the next shot the pirate still clutches John at the neck with his hand. (01:29:25)
Continuity mistake: In the scene after Wendy kisses Peter, Peter comes back down from the sky and cuts the ropes binding Hook. Hook is still tangled in the ropes when Peter tosses him a sword, but in the next shot, Hook flies away from the ropes as if he wasn't ever tangled in them. There wasn't enough time in between shots for him to cut the ropes himself. (01:32:05)
Continuity mistake: When the children return home, the first exterior shot pans closer to show Mrs. Darling sitting in the red chair which is angled towards the window. In the next interior shots the angle of the red chair differs. (01:34:55)
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 Wendy, John and Michael return home, in the wide shot as they look around the two swords in the toy chest, at the foot of Michael's bed, are visible. When they go to their beds Wendy places her Neverland sword into the toy chest, but the two originals' positions differ - the boys' Neverland swords are visible on their beds. When Aunt Millicent walks in with the Lost Boys, as the Darlings hug, the toy chest is visible and the swords are gone. (01:35:10)
Continuity mistake: When the children return home, in a wide shot as they look around the nursery while their mother sleeps in the chair, the table's two legs are positioned near the outer edge of the small red rug. When Mrs. Darling walks out of the room the table is pushed farther back, close to the bookcase. The little rug near the corner curio changes between shots as well. (01:35:15)
Continuity mistake: After Wendy, John and Michael return home, from the shot of Wendy as she puts her sword in the toy chest, to the following shots, the amount of space between Wendy's bed and the corner of the wall on its left changes drastically. (01:35:20)
Continuity mistake: After the children's arrival from Neverland, they are in bed as Mrs. Darling, unaware of their return, stands and walks out of the nursery. In this shot there is a set of eleven identical books and another red book on the top shelf of the bookcase. However, when Mr. Darling hugs John now there are actually fourteen in the set of identical books along with the red book on the top shelf. (01:35:45 - 01:37:15)
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: 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: After the children return home, when Mr. Darling welcomes the Lost Boys to the family the boys all jump on him and then Michael pours the treasure onto the floor. In these and the rest of the shots the small red rug is in the middle of the floor, a completely different position than the previous shots, where it was under the table. (01:38:45)
Continuity mistake: In the scene in the black castle where Hook is about to kill Peter he cuts Pan in the chest with his hook, in the next shot the cut is gone.
Continuity mistake: When Peter & Wendy go to see the mermaids, one of the mermaids places her hand on top of Wendy's, and starts to put her head underwater. In the next shot (filmed from behind the mermaid), before Peter hisses at it, she is upright in the water, not dipping her head under anymore.
Continuity mistake: When Hook makes Wendy tell the story of Peter Pan and subsequently shoots Noodler, the first of the two pirates to go down at storytime, the camera cuts to the next shot and Hook's pistol is out of his hand, which is not only visible, but being held up in the air, as opposed to under his right arm where he shot from.
