Continuity mistake: Extended Version only: When the Sackville-Bagginses are knocking on the door, Bilbo walks to a beam to look at them through the window. In the shot from behind we see that he walks to it and leans his right arm on it, peeking round. From the front he's leaning his whole shoulder on it, looking more relaxed. (00:17:00)
Continuity mistake: After Gandalf arrives at Bag End, in the wide shots looking through the doorway of the kitchen, the white cloth on the mantle over the fireplace hangs twice the length as it does in the next close-up, when Bilbo says, "I can make you some eggs if you'd-" Then, while they're in the kitchen, the white cloth hangs longer again. (00:17:20)
Continuity mistake: At Bag End, with his left hand Bilbo holds a plate with pieces of a sponge cake. The small part of the sponge cake is to the left of his thumb, and the large part is opposite his thumb. When there is knocking at the door, the smaller piece is to the right of his thumb. When he's at the window, the smaller piece is to the left again. As he runs into the kitchen, the large part of the sponge cake is now by his thumb. The plate never switched hands. (00:17:35)
Continuity mistake: The Watcher in the Water holds Frodo upside down, and just as its head comes out of the water, but before its mouth appears, in this shot part of the back of Frodo's cloak is tucked into his belt at the back of his waist. The cloak is not tucked into the belt in the previous or following shots. (00:17:45)
Continuity mistake: Gandalf and Bilbo sit on the bench outside of Bag End smoking and in the distance is the Party Tree, the tents and party lights, etc. from Bilbo's party. During the party, Bilbo is speaking with the lights above him and the position of various tents are shown during the entire celebration. Later, invisible Bilbo comes to the gate at Bag End and the Party Tree with all the tents surrounding it are seen (minus the tent that the rocket took and the tent that the 'dragon' burned). The position and arrangement of some tents, lights, etc. are different in all of these shots. (00:19:25)
Continuity mistake: When Bilbo and Gandalf are smoking pipes before the party, Bilbo makes a hoop with the smoke. The hoop first goes forward in west way position. But in the next shot the hoop is going directly forward in north way position. (00:19:25)
Continuity mistake: At Bilbo's party, in the first shot Merry hoists Pippin up into the back of Gandalf's wagon. We see the arrangement of the assorted things in the back of the wagon. In the next front shot, as Pippin dives into the wagon we see a different arrangement of all those things in the back of the wagon. (00:21:20)
Continuity mistake: During Bilbo's party, in the first shot, as Merry boosts Pip onto the back of the wagon, on the table in front of the tent there are pears, oranges and apples on it. Once Pippin is in the wagon, seen behind Merry, there is one red apple that has appeared at the front of the table to the left of the other fruit that wasn't there before. (00:21:20)
Continuity mistake: At Bilbo's party, when Merry and Pippin set off the dragon firework, they are shown inside a small tent. The tent has dishes and other things in it, and is quite full. When the firework launches, taking the tent with it, you can see that all of the things inside the tent (with the exception of Merry and Pippin) have disappeared. (00:22:00)
Continuity mistake: At Bilbo's party, as the fireworks dragon flies overhead, in the close-up shot, when Frodo calls out, "Bilbo!" the two people behind Frodo were not there in the wide shot just before this shot. This is not due to any Hobbits running. Also in that wide shot, Bilbo moves to Frodo's immediate left, but in that close-up he's away from Frodo, so Frodo has to move closer to him in this shot. (00:23:15)
Continuity mistake: When Bilbo is leaving, he drops the Ring at the doorway, turns and walks out the door. Gandalf steps outside after him. Gandalf never pulls at the door, nor does he even touch it. He stands outside talking with Bilbo. When the door is shown behind Gandalf it is wide open. Bilbo walks down the path with Gandalf looking at him. The next shot is a close-up and we see the shadow of the door opening to reveal the Ring. Then a shot looking up at Gandalf as he steps through the doorway. (00:23:40 - 00:24:30)
Continuity mistake: When Gimli falls onto his knees in front of Balin's Tomb in Moria, in one shot he's a few feet in front of it, in the next he is so close to it, that he could lay his head onto the tomb. In the following shot Gimli is further away again, so he should not have been able to reach it with his head. (00:24:20)
Continuity mistake: As Gimli bows before Balin's tomb in Moria, the camera circles around the tomb and the body which Pippin later disturbs is visible in the background. It appears fairly substantial, is wearing a breastplate and has its head on its chest. However when Pippin touches it the body looks different; more skeletal and covered in cobwebs, with the head in a different position. (00:24:20 - 00:25:20)
Continuity mistake: At Dwarrowdelf, as Gimli runs into the Chamber of Mazarbul toward Balin's Tomb, just past the doorway we see a long stick and a very short axe leaning on the right wall. Later when Legolas says, "Orcs!" Boromir runs to the door and now we see a long handle axe with the big blade on top, leaning on that same wall. This does not refer to the two axes in the corner. (00:25:05)
Continuity mistake: At Dwarrowdelf, when Gimli runs into the Chamber of Mazarbul with Balin's Tomb, once inside seen to his left is a big stone with corpses and armor on and around it. When they hear the Orcs, Boromir runs to the door and we see the same big stone again. That stone and some of the corpses are positioned very differently in both of these shots. (00:25:05 - 00:28:05)
Continuity mistake: At Dwarrowdelf, as Gimli runs towards the Chamber of Mazarbul with Balin's Tomb, we see outside the doorway an assortment of body remains, armor and other objects. Then after hearing the approaching Orcs, Boromir looks out of the doorway, and we see to his left that the various body remains and armor are different. When Aragorn and Boromir close the doors to the room, outside we see the position and/or variety of body remains, armor and objects change again. (00:25:05)
Continuity mistake: As Gimli runs into the room of Balin's Tomb, he stops and says, "No!" and in this wide shot, the huge stone with skeletal remains on and around it is lying away from the wall, just behind Gimli, to his left. He kneels, and after he cries, "Oh no! No!" there is a wide overhead shot of the room. In this shot, that particular stone with the skeletal remains is right next to the corner of the wall now. This doesn't have anything to do with camera angle. (00:25:10)
Continuity mistake: At Balin's Tomb, after Gimli kneels and cries, "Oh no! No!" there is an overhead shot of the room. In this shot we see the papers littering the floor around the tombstone. Next we see an extreme close-up of the tombstone, with the skeletal head to its left and the absence of papers around it. Then, in a close-up of the skeleton holding the book, we see papers again, but they are lying about differently than in the overhead shot. Then in the next shot as Gandalf hands Pippin his hat and staff, the papers are the same again, as in the previous overhead shot. (00:25:20)
Continuity mistake: As Gimli weeps at Balin's Tomb, he says "Oh no. No." There is a wide shot, and this is the first shot of the skeleton and pail resting on the stone well. In this shot, the skeleton's feet and head, which are leaning to its left, are in different positions than in the second shot of it. In the second shot, Pippin backs up towards the well, and the skeleton, with its head leaning to its right is shown. Then in the third shot Pippin turns toward the well as Gandalf reads, "A shadow moves in the dark," the skeleton's head now leans to its left. In the fourth shot, as Pippin starts to touch the arrow, the skeleton's head is now leaning forward to its right. (00:25:20)
Continuity mistake: At Bag End, when invisible Bilbo reappears in the hallway, we see books on the shelf of the coat tree. As Bilbo leaves Bag End, he opens the front door, again we see books on the shelf of the coat tree. In both of these shots, the amount and arrangement of books differ. (00:25:40 - 00:28:30)
Answer: "Fly, you fools"
