Continuity mistake: We see the outside of the Darling's house as Wendy speaks of Alf Mason's ugliness, when she looks out from her window after Nana barks, when she searches the patio with a candle, when Nana is chained outside and when Peter, at a distance, sees the Darlings leave their home for the evening, etc. Among the changes, seen in certain shots, is the house adjacent to the Darling's home and the Darling's patio's appearance and surroundings. (00:01:10 - 00:11:55)
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: When Wendy and John duel, the window in the nursery is closed. In the close up of Peter as he peeks in through the window, it is open, causing the white curtain to blow in the wind. However, in the following shots the window is closed until Wendy and John open it. (00:01:45)
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: 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: 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: Throughout the scenes in which Nana is seen, the markings on Nana's face change in various wide shots and close-ups, due to the fact that different dogs played Nana. (00:02:45 - 00:09:20)
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: 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)
Continuity mistake: Just before, during and after Wendy's inspection by Aunt Millicent and while eavesdropping, in subsequent shots the bow in Wendy's hair changes its position. (00:03:30)
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 beginning when John and Michael are explaining Hook to Aunt Millicent, Michael's hair is at first neatly parted, but then it becomes messy and then back to neatly parted. (00:03:45)
Continuity mistake: When Aunt Millicent is speaking with Mr. and Mrs. Darling about Wendy, she is holding a wine glass with engraved etchings. The position of the markings vary when the camera faces her and when the camera faces the Darlings. (00:05:45)
Continuity mistake: There is a shot of Nana sleeping in her house before we see Peter flying over Wendy, who is also asleep. Then there is another shot of Nana coming out of her house barking. The toys' positions near Nana's house differ in both shots and Nana did not move them. (00:06:05)
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: While Wendy, John and Michael are walking home from school, the letter carrier passes by in front of them. In the wide shot the braided hair on Wendy's left is behind her shoulder, yet in the following close-up both sides with bows are in front. (00:08:10)
Continuity mistake: After arriving at the bank, the young letter carrier pulls out the envelope addressed to Mr. Darling and holds it out in front of him. Yet in the next shot facing Mr. Darling the letter is held the opposite way, in the boy's still outstretched hand. (00:09:10)
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: 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: 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)
