Continuity mistake: On the pirate ship, when the watch is first seen, the time jumps all over the place. First, it's 6:32. Then it's at 6:34, then jumps to 6:42, then 6:38. Then after Hook gets up to find the ticking, it's at 6:27, and when Smee picks it up, 6:44.
Continuity mistake: In the ship, the watch reads 6:44, but when they're in Hook's clock museum, they lay the watch down and it reads 2:14, seven and a half hours for a five minute walk.
Revealing mistake: As Peter pulls himself up to look over the brick wall, the entire snow drift on top moves, showing it's set dressing.
Continuity mistake: When the coconut flies at Peter, he spins, swings, and completely misses it. Then shown from another angle, he repeats the move, only to hit the coconut, but this time has his eyes closed in preparation for the liquid to fly everywhere.
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: When Peter gets his happy thought, he floats just above the ground in his regular clothes. As he shoots upwards toward the top of the tree house and out, he suddenly has his Pan clothing on. After returning, he suddenly has his normal clothes.
Continuity mistake: In the final fight, Pan's sword is golden colored. When he gives it to the Lost Boy, it's silver.
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.
Continuity mistake: When Peter sneezes Tink into the dollhouse, the angle doesn't make sense, as they were parallel to the house, yet Tink goes flying into it straight, as if they had been perpendicular.
Visible crew/equipment: When Peter arrives in Neverland he walks up to some pirates and says, "I'm looking for someone". The pirates chase him and Tink beats them up. In one shot, when a pirate is being thrown from a balcony, there is a launch pad in between the slats.
Answer: 1) Though it is never fully explained, the mystical way Peter Pan would come and go from Never land. 2) It was Smee who was doing the spying. When Hook asked Smee, "This can't be my great and worthy foe?" Smee replied, "I have all the information here." He had a file of paper work on Peter. 3) Hook knew where the Lost Boys were, When Peter asked, what happened to the Never Tree. Tinkerbell said, "Hook burned it when you didn't come back." He considered the Lost Boys not worth the effort. It was Peter, he wanted.
