Continuity: After Lurtz releases his first arrow at Boromir, one of the Hobbit stand-ins is seen to Boromir's left, throwing stones. The next shot is of Merry and Pippin standing close together, looking at Boromir to their left - they have moved position to the other side of him.

Continuity: 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 scene Gimli is further away again, so he should not have been able to reach it with his head.

Continuity: As Sam, Merry and Pippin run across the grass towards the Bucklebury Ferry, they have two shadows; bold ones behind them, presumably meant to be from the moon, but also unexplained faint ones to their right. (This is before they pass the cottage, so it can't be light from the weak lamps hanging outside.) When Frodo is then pursued by the wraith his shadow is in front of him, yet he is running in the same direction as the other hobbits were.

Continuity: When the hobbits are hiding under the tree trunk from the Ringwraith in the beginning, you can see space to the left and right of the tree above them. Logically when the Ringwraith walks past the tree you would see it on the right side of the tree first, then on the left, but you don't - it looks like it walks out of the tree instead of behind it. [Confirmed on the commentaries - Elijah Wood asks his fellow actors if anyone spotted the mistake: 'It kind of magically comes out of the tree'. Sean Astin: 'You mean it doesn't pass from the other side?' Wood: 'No, it comes out from the centre.']

Continuity: In the Amon Hen battle scene, at the start of the fight with Lurtz, Aragorn is slammed backwards against a tree knocking his sword out of his hand. There is then a shot of Lurtz throwing his shield at Aragorn, and in the following shot, where the shield pins Aragorn against the tree, his sword is still in his hand, only to fly out again on the shield's impact.

Continuity: When Gandalf pulls Sam in through the window at Bag End and throws him on the desk to ask him questions, several items fall off of the desk. The scene switches back and forth between Sam and Gandalf's perspectives several times. When Sam is shown, the arrangement and appearance of items on the floor below vary. In some shots there is a wooden box and book on the floor to the left side of Sam's head and/or a book and paper to the right.

Continuity: In the scene where Gandalf and Saruman are fighting, Gandalf is thrown to the ground and starts bleeding. But if you look carefully, every other shot Gandalf has blood on his face, then none, then more blood, then none.

Revealing: When Gandalf first visits Bilbo in Bag End they sit at a long table that is positioned lengthways from the camera. Bilbo potters about at the far end of the table and Gandalf goes to the left at the end closest to the camera. As he sits down the near half of the table wobbles but the far half does not. This seems to expose the fact that the table is actually in two parts, a small sized piece of table close to the camera next to which Gandalf looks large, and a normal sized piece of table a bit further away that looks the right size for Bilbo. The two pieces are filmed from such a perspective that they look like they join together in one long table and the fact that there is really a gap between them so that Bilbo is further away than it seems, makes him seem small compared to Gandalf. There is a round of cheese and various pieces of crockery on the near piece of table to disguise the gap.

Continuity: Boromir gets shot by Lurtz's second arrow, drops down to his knees in front of Merry and Pippin, gathers strength, turns around and stabs an Uruk. In the next wide shot and close-up, he stands and is about to stab an Uruk in the back and the two arrows in his chest are there. Yet, in the next wide shot, as his blade is going down into the Uruk, Boromir has only the lower arrow in him, the one near his shoulder is NOT there, for 23 frames. In the next close-up, the upper arrow is back. These arrows are NOT CGI.

Continuity: Saruman's Orcs are busy tearing down trees for firewood. In the second shot of this scene you will notice that one of the Orcs in the central foreground falls on his backside as the tree hits the ground. A few shots later, the same group of Orc's are pulling down the same tree, just filmed from a different angle. You can see the Orc falling down once again, this time on the left hand side, behind a burning brazier.

Continuity: When Boromir attacks him, Frodo frantically slips the Ring onto his middle finger (with the chain). Yet, as Frodo runs up the steps of the ruins, Boromir yells, "Frodo, I'm sorry!" and Frodo wears the Ring on his index finger. He is terrified, so as to remain invisible he does not change fingers.

Continuity: When Gandalf meets Frodo for the first time and gives him a ride into Hobbiton on his wagon you can see that at the start of the sequence his wizard's staff is near Frodo's shoulder. In the back shot as they go over the bridge and another shot, the staff is to the rear of the wagon. In the very next shot, a close up, the staff has reappeared near Frodo's shoulder again. Also, as Gandalf goes up the hill in front of Bag End, his staff is sticking out the back of the wagon, but in the following close-up as he stops the wagon, the staff is right next to him. Other contents of the wagon also change position during the journey.

Continuity: During the scene when Isildur cuts the Ring from Sauron's hand, it is obvious that he is against a pretty tall rock wall. But, when we see an overhead shot of the Dark Lord exploding, there is no rock wall. Notice how there are soldiers all around the explosion.

Other: When Arwen and Aragorn are talking on the bridge, you see Arwen's lips moving while Aragorn is speaking. When you zoom in you can see that Arwen's mouth is definitely moving as she is talking animatedly, both when neither character has any dialogue and when Aragorn's voice says 'I thought I had strayed into a dream'.

Continuity: When Gandalf and Saruman are talking in Orthanc, we can see a black strap around Gandalf's fingers on the hand holding his staff. In some shots it's around different fingers, in others it's disappeared completely.

Revealing: During Arwen's race to the Ford of Bruinen, she rides at least two different horses. The first horse seen is a lovely grey (white and black hairs) and is likely to be of Andalusian descent. The second horse is a fleabitten grey (white with red hairs) with COMPLETELY different hind-end conformation and muscling, and looks as if it is an Arabian. The switch occurs several times. If you aren't a horse person, you can see this change by watching the horses' necks. The first horse has a very thick neck, and the second horse's neck is much thinner.

Visible crew/equipment: After Frodo looks into the mirror and sees the destruction of the Shire, Galadriel is seen riding in the swan boat across the river. Look in the background, on the left bank, a man can been seen sitting there, very faintly. As the scene progresses this crew member can be seen looking back and forth.

Continuity: In one shot of Gandalf's first appearance at Bilbo's front door, he is wearing light-brownish shoes under his robes, and when he walks in, he's got his normal grey ones on.

Continuity: Just before the scene changes to Saruman on top of Orthanc, the shot zooms out from the Fellowship attempting to climb Caradhras. Legolas (recognizable as, being an Elf, he is standing on top of the snow) is to Gandalf's left. When the scene resumes he has moved back some distance to Gandalf's right, closer to the rest of the Fellowship. The camera pans upwards as the avalanche falls and as we follow its descent, Legolas runs out from Gandalf's left to pull him clear. Even for an Elf that's a lot of quick, (and unnecessary), movement.

Continuity: Right at the end, Aragorn is telling Legolas and Gimli, "Let us hunt some Orc." In the two close-ups of Legolas that follow, the colour of the feathers on his arrows are light green, differing from the Mirkwood arrows he always carries. These close-ups were shot as pickups, months after filming ended. Commentary, extended DVD.
