Continuity mistake: The stuff that hit Rufio was originally blue with a touch of red and covered much of his face. Less than a minute later, it's mostly gone, but has changed to dabs of green with a touch of yellow over his left eyebrow.
Continuity mistake: Peter picks up a wooden spoon and flicks imaginary food at Rufio. Looking at Rufio, a black plastic spoon covered in blue flicks some blue and red substance at him that has a consistency if pudding. When Peter looks at the now-covered spoon, it has red, green, yellow and blue stuff stuck on it.
Continuity mistake: As Rufio makes his entrance, he swings on a twin roped bar, and a second later he's on a single vine, with nothing else nearby to swing on or from.
Revealing mistake: As Tink flies around waking up the Lost Boys, as she flies by the red-headed kid, the wires operating the puppet are visible.
Visible crew/equipment: As the hook is locked into place, there are several pyrotechnic charges set off, one of which can be seen exploding directly underneath the hook. Also, the studio lighting is reflected in the chrome finish.
Visible crew/equipment: As Jack walks away after striking out, the studio reflecting panels can be seen on his helmet.
Continuity mistake: As Peter selects the largest Lost Boy, he stops, and holds the sword out. After the angle change, he stops again.
Continuity mistake: During the sword fight between Pan and Hook, Pan switches the sword from right to left. After dodging a thrust, it's suddenly back in his right.
Continuity mistake: Between camera angles the angle of the pistol Hook holds to his temple switches from angled to straight on and back.
Continuity mistake: The lane switch on the overhead path is just off center so neither track is complete. As Peter begins to run, the piece is in place, presumably because Rufio came through, but there is no evidence of an automatic switching device.
Other mistake: As Peter stands on top of the rocks, you can see a distinct difference between his appearance and Never-land. Also, as the camera pulls back to follow his progress through the Lost Boys area, a vine is seen shaking on the left side because the camera hit it.
Continuity mistake: As he gets ready to swat at Tink, Peter's hair style changes.
Revealing mistake: Many times during the film when characters are flying, it is clear that they are flying on a harness due to their stiff, rigid movement and also due to the bulkiness that will suddenly appear on their back. It is especially noticeable at the end when Tootles sprinkles the fairy dust over himself and flies out the nursery window. (02:09:20)
Continuity mistake: At the end of the movie when Peter crawls into Nana's doghouse to greet her (after returning from Neverland) he shakes the doghouse a little as he crawls in, causing snow to fall of its roof, which lands in the two dogbowls next to it. But in the next shot the dogbowls are now empty with no snow in them and also there is a long bone sticking out one of the bowls too. (02:06:20)
Continuity mistake: When the nursery windows are opened (as Peter and the kids return) we see an orange leaf float inside the room and land on Moira's neck. In the next shot it is on her shoulder. (02:03:00)
Continuity mistake: When Peter gives the sword to the Lost Boy he chooses to leave in charge of Neverland, the Lost Boy holds the sword out, upright. In the next shot he is holding it down and once again lifts it upright. (02:02:15)
Continuity mistake: When Peter is leaving Neverland near the end of the film, he is talking with the Lost Boys, and they asks which one of them he should leave in charge of Neverland. As he does, he removes his sword from its sheath - twice between shots. (02:01:30)
Continuity mistake: When Peter Pan is battling with all of the pirates on Captain Hook's ship, he continues to knock them all to the ground with his sword. As the shots change during the scene, the positions of the pirates that lay on the floor keep changing instantly after they fall. (01:44:50)
Continuity mistake: When Smee is bent over at the water tank that has Hook's toy ships in it, in one shot as we see the shot with Hook's back facing the camera, Smee's bandana ties both hang in front of his shoulder. In the following shot the ties are now differently positioned, with one folded back over his shoulder. (01:00:05)
Answer: Neverland very much runs on "If you believe, it will happen" which is what Tink means during the meal when she says "If you don't imagine yourself as Peter Pan you won't be Peter Pan." So by the rules of Neverland, as soon as Peter believed it was real it was then real. The dinner was trying to teach him to believe as, in Neverland, if you don't believe it then it won't happen.
