Continuity mistake: After Boromir is hit with the second arrow, he falls to his knees. When he shoves his sword into the Uruk in the close-up, the silver clasp on Boromir's red shirt, at the center of his torso, is not clasped to the red loop on the opposite side (but it was in previous shots). However, in his extreme close-up, when he screams out, it is properly clasped like the rest on the red shirt, but in the very next shot it is not clasped yet again, and of course it is in following shots.
Continuity mistake: At Amon Hen, when Frodo asks of Aragorn, "Can you protect me from yourself?" there is a close-up of the Ring in the palm of Frodo's hand, which is clearly Elijah Wood's hand - his fingernails are so bitten up that there are barely any left. A moment later, in the two following close-ups, first when Aragorn's hand nearly touches the Ring and then when Aragorn's hand closes Frodo's fingers over the Ring, Frodo's hand is certainly not Elijah Wood's - the fingernails are regular length.
Continuity mistake: When Gandalf comes to Minas Tirith, the river is noticeably closer to the city than it is in "Return of the King."
Continuity mistake: At Bag End, Gandalf tosses the envelope with the Ring into the fire. He grips tongs tightly between his thumb and other fingers and reaches into the fire with his thumb facing his left side. In the close-up, the Ring is grasped on the same side as his thumb, with the excess Ring on the other side with his other fingers. Yet in the next shot, Gandalf lifts the Ring out of the fire and the Ring is grasped on the same side as his other fingers, with the excess Ring at the same side as his thumb. This has nothing to do with camera angles.
Continuity mistake: In the opening shot of Bag End, as Bilbo says, "The Third Age of this world," we see the halls outside of Bilbo's study as Bilbo writes. There is a dresser with books on it, books lying near the coat tree, stacks of books and papers all over the floor and against the walls. Later, just before Bilbo says, "Frodo, someone at the door," and then when Bilbo searches for the Ring in the hall, in all three of these shots, the arrangement or even existence of quite a few of those books and papers is different. This has nothing to do with his search of the Ring.
Continuity mistake: At the Council of Elrond, when Merry and Pippin run up and yell, "We're coming too. You'll have to send us home tied up in a sack to stop us!" Elrond's eye contact does not line up with the Hobbits, as they run past him towards Frodo. Then in the Hobbits' close-up, their height reaches just under Gandalf's and Legolas' shoulders, but in the wide shot the Hobbits are much, much, shorter.
Continuity mistake: After spotting the Crebain from Dunland, the Fellowship try to hide. Just after Frodo and Aragorn hide under some boulders, there is an aerial shot of the area. Frodo, holding the green cloak, can be seen ducking behind the tall boulder on the left, even though he's shown already hiding in the previous shot.
Continuity mistake: At Bag End, Bilbo invites Gandalf in and he hands Bilbo his staff and hat. Before the hand off, the knot of the wrist strap on the staff is seen just as Gandalf says, "Bilbo Baggins." and the rim of his hat is seen throughout. After the hand off, as Bilbo carries the large staff in front of him, the strap hangs down and it's a different knot than seen before. The rim of the huge prop hat is seen when Bilbo puts it down and there is a slice on the rim that was not there before.
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.
Continuity mistake: At Amon Hen, Merry and Pippin run from the Uruk-hai after distracting them from Frodo's escape. After they run over the bridge, the next shot is of the two of them stopping short when Merry sees more oncoming Uruk-hai. In this shot it is only Pippin's Elven brooch that is facing the opposite way it normally faces.
Continuity mistake: When Gandalf says, "Mellon," the doors to Moria open and they all go in. Legolas soon picks up an arrow and says, "Goblins!" When he does so, we see the left long braid is loose at the end and coming undone. After Boromir shouts, "Legolas!" in the close-up we see the perfectly made long braid hanging down.
Continuity mistake: After hearing noises out the window, Gandalf tells Frodo to, "Get down," and reaches for his staff leaning on the mantle. In the close-up when he grabs the staff, on the mantle there are books on the left end with a box near it, and a piece of paper leaning up against the wall between the two. In the wide shot just before this shot, there is no paper between the books and box. Also, the paper lying between the books changes from previous shots and when he starts heading for the window, behind him on the mantle the paper to the right of the candlestick changes position in the following shots.
Continuity mistake: Frodo is in the kitchen packing apples and other food for his journey to Bree. Frodo asks Gandalf, "And the Ring will be safe there?" Behind Frodo, to his right, the window and table in the next room are seen. The chair near the table, is not the same chair that is next to that table in all the rest of the shots of the area. The window is shut, but when Gandalf and Frodo are soon in there it is open when Sam isn't "dropping no eaves." It cannot be assumed that Sam would have opened the window. The existence and arrangement of books and papers on the window bench also differs.
Continuity mistake: In the scene in Isengard, when the Orcs are digging the Uruk-Hai out of the mud, it shows a Uruk-Hai grabbing the throat of an Orc. When he first grabs him, and it shows the Uruk-Hai, its got relatively clean shoulders. When it shows him again, there are piles of mud on his shoulders and chest. Than when it shows him standing up, there is no mud on his shoulders or chest, but he is covered in slime.
Continuity mistake: When Gandalf and Saruman are about to fight, Gandalf switches his staff from his left to his right hand. When Saruman smashes him against the wall, the staff is back in the left hand.
Continuity mistake: Not only do the arms on the two large statutes at Amon Hen change, the statutes themselves switch places. When we first see them, the statute of the younger man has a winged helmet and is on the left and the older with the smooth helmet is on the right. In the shot once the boats have gone past, the winged helmet statute is on the right and the smooth helmet statute is on the left.
Continuity mistake: Just after Gandalf enters Bag End for the first time he looks the map of Middle Earth on the table. In first shot when he is grabbing the map, you can see that there are two scrolls and a flat empty paper stacked on the map. In next shot, there is only one scroll and a paper with some kind of pattern on it.
