Continuity mistake: When Peter flies through the nursery and stops at the drawer with his trapped shadow, the door to the nursery remains wide open behind him. Yet, when Aunt Millicent checks on the children she, both visually and audibly, opens the bedroom door. (00:13:10 - 00:14:15)
Continuity mistake: When Wendy is tied up aboard the Jolly Roger the amount and/or position of rope around her differs greatly between shots. For example, when Hook shoots Noodler it's wound around 6 times - on her left it's 3 over the wood and 3 under, yet when Hook cuts the lines it's wound 5 times - on her left it's 4 over the wood and 1 under. (01:18:20 - 01:19:20)
Continuity mistake: Tinker flies into the nursery, zips around the room and in the shot from under John's bed goes to the wardrobe with the hanging clothes. Then in the close-up she plunges into all the readily available pockets. These clothes which are seen in many following shots too are quite different in the later shots, not to mention the significant difference of the close-up with all the pockets in perfect position for Tinker Bell to fly in and out of. (00:12:30 - 00:15:20)
Continuity mistake: At the bank Nana skids and picks up the two passengers and they all advance towards the bankers. As the boy runs and then as all three approach the bankers, the bankers behind Mr. Darling are positioned differently depending on the camera's angle in each of the far shots, close-ups and overhead shot. (00:09:10)
Continuity mistake: When Wendy is at school she puts down her needlework and flips the page in her notebook to the page with the drawing of Peter and as she flips the page the drawing is seen. In the next close-up, the drawing seen here is different from the one seen in the previous shot. Two examples of the difference are Peter is much closer to Wendy and he has no wings in the wide shot. (00:07:15)
Continuity mistake: At the bank, in the close-up of her legs Nana knocks Wendy off her feet and she lands parallel to Nana. In the next close-up of her face Wendy falls back again. Then in the next close-up Wendy falls perpendicularly to Nana. (00:09:20)
Continuity mistake: Peter flies in and tells everyone of the new pirate Red Handed Jill and as he says, "She's just a storyteller," the small piece of watermelon, that looks as if it's been hacked already, is visible on the table. Then when he says, "I shall run her through!" he slams his blade into a large wedge of watermelon - its shape is very different (before the blade hits it of course). Other food on the table differs in consecutive shots within this scene as well. (01:04:30)
Continuity mistake: The scene after Hook gets swallowed by the crocodile Peter puts on the hat that Hook tossed into the water earlier. But in the close up shots of Peter, the hat with its feathers look perfectly dry, contradicting the very loud splash it made when it hit the water. (01:23:40 - 01:33:35)
Continuity mistake: Near the beginning of the film we see a tree outside the window, but when Tinkerbell flies in towards Peter (who's at the window) there is no tree. (00:02:00)
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: 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: 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: 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 John realizes that he has forgotten his parents and that they must leave, Peter shouts, "If you wish it!" The positions of some of the kids differ in the front shots and back shot. (01:06:25)
Continuity mistake: Wendy places a flower full of medicine near the wooden crocodile for Peter to take. After Hook sneaks in he spots the flower and then places the poison inside it. Then when Peter wakes up and calls out, "Wendy," he sees the flower. In all three shots the wood chisel, wood chips, flower, etc. are different. (00:09:25 - 01:11:50)
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 pirate hat hanging on John's foot board first faces him, then faces the camera, the toys on the floor in front of Michael's bed, etc., change position between the shots of Peter entering the nursery and when Aunt Millicent opens the bedroom door, even though no one moved anything between these shots. (00:13:00 - 00:14:20)
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 John and Wendy duel in the nursery, Wendy ducks beside the table and John plunges his sword into the bookcase as he lands face down on the table knocking things off. In the next close-up of Nana, the table is visible behind her with no sign of John or Wendy and toy soldiers sit upright at the edge of the table. (00:01:50)
Continuity mistake: Mrs. Darling plays the piano and when the children start dancing around Aunt Millicent we see the small red velvet pillow on the table to her left. In the next wide shot as they dance, Mr. Darling settles them down and the pillow is not on the table, yet in Aunt Millicent's close-up the pillow is there as before. (00:03:20)
