Continuity mistake: When it shows the plane flying to London, in the first shot we see it is a huge craft but when it shows the inside it is very tightly compact and narrow.
Continuity mistake: When Peter Pan starts fighting Hook's pirates on the ships deck, he pushes the second pirate who attacks him into two barrells. Where the pirate is pushed, there are two barrells (which he flies into), a large wooden crate, and another large wooden crate with a barrell laying on it. Then when it cuts, there's now THREE small crates instead of the one large one, and there's now TWO barrells on top of the other crate! (01:44:50)
Continuity mistake: When Hook is bent down talking to Jack in the shop full of broken clocks, his hand keeps moving from either resting on Jack's shoulder or his arm. (01:22:00)
Continuity mistake: When Tinkerbell first arrives at Peter's home, she walks through ink and then walks on Peter's shirt, making little footprints. She only walks halfway up his shirt, yet when Peter gets up you can see little footprints leading all the way up to his collar. (00:30:35 - 00:31:30)
Visible crew/equipment: After one Lost Boy fires an arrow at Peter's butt, you can see a thin piece of fishing wire that hangs past the bow and in front of the Lost Boy, either used to launch or control the arrow. (00:53:40)
Revealing mistake: During the big fight between Peter and Hook, Hook scratches Peter on the arm with his hook. If you look closely when this happens, you can see the hook bend on Peter's arm, a rubber hook with fake blood on it to make a realistic scratch.
Revealing mistake: When Tink visits Peter at Wendy's house and pulls the rug from under his feet, if you look at his legs, Peter jumps up before the rug is pulled. (00:33:15)
Revealing mistake: When old Peter recalls going to Wendy's nursery when he was younger, there is a scene of him trying to catch his shadow from the wall. Yet you can see his real shadow, cast on the mantle and wall to his right. (01:33:25)
Visible crew/equipment: When the pirates try to get Peters shoes, after he first arrives at Neverland, Tinkerbell starts fighting them. In one shot a pirate gets hit by a very large saucepan, and falls back-first off a balcony. The very long wire is very visible. It's really long and goes all the way from attached to his back, to offscreen. (00:36:00)
Revealing mistake: When the biggest "lost boy" curls into a ball and rolls down the gangplank scattering pirates, he was obviously a dummy. (01:48:10)
Continuity mistake: When Peter's daughter shows the drawing on the plane, he asks "where is my parachute? A shot later the girl disappears.
Visible crew/equipment: White lighting screens are reflected on Peter's glasses when he looks up to see Rufio for the first time, and right afterwards when he runs away and bumps into a net.
Visible crew/equipment: When the assistant shows up to film Jack, the studio lights reflect on his glasses.
Continuity mistake: When Maggie shows Peter the paper flower that Tootles made for her, she holds it with both hands but in the next shot is only holding it with her right hand. Also the "stem" of the flower changes from being rather straight to slightly crooked. (00:18:10)
Continuity mistake: When Peter is fighting Hook in front of the crocodile clock, he uses his sword tip to fling the pirate-hat and its wig attachment off of Hook's head and it flies over and lands on one of the Lost Boys heads. When it lands on his head it is wonky. But in the next shot it is sitting on his head perfectly straight and is then wonky again in the next shot. (01:57:00)
Continuity mistake: When Peter is hit by the flying baseball that knocks him out, when he falls to the ground he has nothing attached to the large black belt that goes around his waist. But in the very next shot there is a small brown pouch that is tied to the belt, to his right side. (01:28:10)
Continuity mistake: When Tinkerbell first meets Peter, she is walking on him as he lays in the cot. Peter's glasses always lay under his chin, because they fell off his nose, but when he gets up from the cot the glasses are suddenly in his hand. (00:31:20)
Audio problem: In the scene when Robin Williams is giving the speech at the presentation for Wendy, when the shot changes to show Wendy and Moira, Robin's voice changes to a voice over, and then back to normal when he is shown again. (00:19:00)
Continuity mistake: When the window opens and the children are kidnapped, the tent gets blown over. Yet later when Peter re-enters the room and pours a drink, the tent is back up. (00:22:25 - 00:29:40)
Revealing mistake: When Peter gets out of the water, (after the encounter with the mermaids), he stands up and looks over Neverland. When he does this, the background is obviously a greenscreen shot, because matte lines are visible on Peter. (00:49:20)
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.
