Continuity mistake: The long cut on Peter's upper arm changes length, position and even its angle in quite a few shots when it is visible, in the Black Castle, followed by Peter and Wendy at the fairy dance and then after their own dance. (00:52:50 - 00:56:45)
Continuity mistake: Smee opens the door to Hook's stateroom, calls out, "Cap'n?" and from the exterior we see the large globe to the left. When Smee walks in, the globe is seen again from the other side, but the globe shows the exact same region and markings as when it was seen from the doorway. (00:27:35)
Continuity mistake: At the start, when Mrs. Darling plays the entry music for Wendy to tell her story, her hands lift up a little from the piano, but do not appear to move along the keyboard far enough for those notes to be played properly. (00:03:35)
Continuity mistake: In the bathtub Michael says, "Not fair," to Nana and his hair is combed differently, parted and much neater, in the next close-up. (00:02:45)
Continuity mistake: Peter stands at the window and says, "Come away to Neverland." In the close-ups as his hands grasp the curtains, hardly any of the white curtain is seen under his grip. Yet in the wide shots there is much white curtain seen in his hands. (00:22:30)
Continuity mistake: As Peter saves Wendy and scares away the mermaids his body position is very different in the wide shot between the two close-ups. (00:42:45)
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 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)
Continuity mistake: As Wendy approaches the Lost Boys to give them their medicine, in the close-up they surround Peter begging to be killed. In the next wide shot Tootles pulls one of the twins close and puts his arm around him, though in the next shot they are positioned as they were in the first close-up. Wendy's necklace changes within these shots as well. (00:39:15)
Continuity mistake: After Wendy admits to being Red Handed Jill, Peter holds his blade to Wendy's throat. In the first close-up Peter grasps the hilt so the sharp curved edge of the blade points towards the knuckles of his fingers. In the second close-up his hand grasps the hilt so that the sharp edge points towards the palm of his hand. (This has nothing to do with how his wrist is turned.) (01:05:30)
Continuity mistake: When Wendy walks the plank she stands at the edge and as the camera faces her the brilliant sunlight from behind her highlights the plank and casts a long bright shadow in front of her, contrary to the dark wood plank in the overhead shots. (01:20:10)
Continuity mistake: After the Lost Boys fire their arrows at the Wendy-bird, the position of the arrows on Tootle's back differs in the front shot and back shot as they watch the arrow hit Wendy. (00:33:35)
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 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: When Hook has Wendy tell him the story of Peter Pan a pirate says, "I need a Wendy," and Hook shoots him. Then Smee says, "Very exciting. Two dead already," Hook does not put the gun away in the background, yet in the next shot he has no gun in his hand. (01:18:15)
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: When Hook slices Peter at the Black Castle, we see very that Hook cuts Peter directly below the jugular notch at the neck. Yet in the following shots the cut is shown to be far below the original cut made nor does it have the same appearance within those shots as well. (00:50:25)
Continuity mistake: In the nursery, John shouts, "I've got it! I've got it!" then runs to his bed and visible on the left are clothes that hang from the tri-fold screen which stands near John's bed. In the close-up of John's feet, as he runs on his bed to try and fly, one set of clothes from the previous shot is gone. When he lands on the floor, there is yet another set of clothes that hang under the outfit with the white ruffle as well and then as John flies out the window still another set appears. (00:21:30)
Continuity mistake: Peter, Wendy and the boys are on the cloud looking down on the Jolly Roger when Wendy comments, "She must do 12 knots under full sail." In this wide shot we see Noodler standing at the snow topped rail between the cannons. John then views Noodler in a close-up and the snow is different, there are lines lying on top of the cannons, etc. (00:29:55)
Continuity mistake: When Wendy tells her story while tied up on the Jolly Roger, there is a front close-up of Noodler who raises his 'left' hand to ask, "Was one of them pirates called Noodler?" Then there is a back shot of Noodler who is still raising his hand, but it is his 'right' hand that is raised and then moves to the front of his body. It is not the wart pirate's hand in the back shot, whose hand is on Noodler's shoulder in the next front shot. (01:18:15)
