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)
Visible crew/equipment: At the Black Castle, Wendy, John, Michael and Tiger Lily jump down into Smee's boat. In the wide shot as they land in the boat, seen under John's gown at his backside is an outline of the square apparatus and Wendy's nightgown is gathered up and pulled at her back from the line that is attached for her descent. (00:49:50)
Other mistake: At the very end of the movie, Peter says "to hear stories about me" and we see Wendy and her eyes are moving as if watching him fly away, but when it cuts back to Peter he then starts to fly away.
Audio problem: When trapped underwater in the net at the Black Castle, Peter pulls out his knife from his small leather sheath underwater and we hear a metallic rasping sound which it should not make since it isn't scraping metal. (00:49:55)
Audio problem: Peter tells Wendy, John and Michael, "There are mermaids! Indians! Pirates!" We hear the children repeat, "Pirates!" but their mouths do not actually say it. (00:22:45)
Continuity mistake: In the Black Castle, when the croc appears outside the gate on the rock, we see in the left corner of the screen the children in the boat with Wendy standing up, next shot is of them all jumping to the side of the boat looking out over the water to the croc, the very next instance, when the croc is climbing down off the rock, the children are now back in their original positions again in the boat. (00:51:00)
Continuity mistake: On the Jolly Roger, Hook slashes one of his men and asks, "Any other contributions?" The pirates are positioned differently in the shots facing Hook and in the shot facing themselves. (00:32:15)
Continuity mistake: In the nursery, behind Michael's and John's beds there are many small soldiers and horses perched on the chair rail (decorative molding). The position/amount of these soldiers and horses differ significantly in consecutive shots within the scene before they leave for Neverland and also within the scene when they eventually return. (00:12:25 - 01:35:25)
Continuity mistake: While duelling on the Jolly Roger, Wendy and John back up into each other, turn their heads to look at one another and scream face to face. In the next shot Peter flies towards Hook and in the background on deck below, Wendy and John are standing apart and facing the same way. Then in the next shot they are still back to back while screaming face to face. (00:24:35)
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)
Revealing mistake: Peter has a cut on his left arm and after dancing with Wendy Peter shouts, "Go home and grow up... take your feelings with you!" then Peter flies off. As the narrator says, "Peter did not want Wendy to leave...he visited Wendy's home..." when Peter arrives at the nursery window, the long cut on Peter's left arm is GONE, not changed in any way, just simply gone. It reappears later when Hook shouts, "It's Hook! He flies!" only to disappear again! (00:56:50 - 00:58:10)
Revealing mistake: At the Black Castle, Hook slams Peter down on a rock, leans over him and proceeds to cut Peter's chest with the tip of his hook. Before the hook touches Peter's skin, we see a mark on Peter's skin where the hook is to begin its slicing, that was not there before. Then as the tip actually slices him there is no cut or blood seen, it obviously does not have any effect on Peter's skin. (00:50:25)
Continuity mistake: After Wendy is shot by Tootle's arrow, while she lies on the ground the boys are gathered around her and Peter takes his "kiss" from under the neck of her gown. The "kiss" is looped onto the chain around Wendy's neck, but in the next shot Peter holds it without the chain. He could not have removed it from the chain, which is still around her neck, so quickly. (00:35:25)
Revealing mistake: When Michael is riding Nana down the hallway towards the bath, he is naked, though it is plain to see that his entire body is not seen even when he flips, it is simply skin coloring. This part of his body was digitally augmented, as he was filmed wearing a covering on his privates. (00:02:40)
Continuity mistake: Just before Wendy and John begin sword fighting, Nana backs up into her doghouse. Two shots later, when John grabs his sword, Nana stands between her house and the dresser, but then two shots later - with her hind in the house - Nana walks out of the doghouse. (00:01:25)
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: 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: In the exterior wide shot, as Wendy opens the window of the nursery the curved window guard rail is seen being right up to the edge of the ledge below the window. In the shot from above as Wendy, John and Michael look up, the guard rail is not in this particular shot. (00:02:05)
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)
Continuity mistake: When Princess Tiger Lily finds the two boys hanging upside-down in a snare, she is looking forward at them, and then falls backward laughing and rolls down an embankment. When the two boys start yelling at Hook, they all look straight up to see them, though they should be a good ten feet from that spot. One may argue she went back to that spot when trying to retrieve her knife before the pirates caught her, but even then, she was holding the knife when she fell, and would still be far from the right mark. (00:40:45 - 00:41:45)
