Corrected entry: In the scene where Eomer of Rohan gives Aragorn, Legolas and Gimli two horses it seems they have appeared out of thin air. When you get a birdseye view of the riders you can see no free horses and when Aragorn calls them back there are no free horses. It can't be that other riders volunteered them, as Eomer states that he hopes that Aragorn, Legolas and Gimli are more fortunate than their original owners, indicating that they perished in the battle with the Uruk-hai.
Corrected entry: In the scene at the end of the extended edition where Legolas and Gimli are comparing their battle scores, Legolas is wearing a long sword in a sheath hanging from his belt. At no other time in the movie does Legolas have a sword, even after he dons armour for the Battle of Helm's Deep. He has his bow, and his two knives which he occasionally whips out of the sheath on his back.
Corrected entry: In the Warg battle scene, Gimli is being charged by a creature and Legolas shoots it for him. He yells out, "That one was mine." and is surprised by another behind him. He strikes it, and it falls on him. Look at the axe in the shot where they fall - the handle is facing the wrong direction.
Corrected entry: In the scene where the uruks plant the bombs in the culvert at Helm's Deep and then proceed to blow it up. You see in one shot that the culvert has not been dammed/blocked in any way and in another shot you see a small stream of water flowing freely through it. Why then do we see such a torrent of water flowing trough the gap once a hole is blasted in the wall? (02:12:45 - 02:13:50)
Corrected entry: During the fight in Gondor (before Frodo and Sam were released), the camera gives us a bit of a view of the archers. One archer that is crouched behind a stone piece is seen dodging arrows that aren't there. Then all of a sudden he collapses onto the rock, although he was never actually hit by anything.
Corrected entry: Because the title of the film is very similar to a nickname of the World Trade Center towers ("Twin Towers") and their connection to the September 11, 2001 terrorist attacks, director Peter Jackson considered changing it, but quickly decided against it because of fan opposition.
Corrected entry: In the film, the two towers in the title refer to the fortress of Barad-dur, and the tower of Orthanc. In the book, the two towers being referred to were the towers of Orthanc and Cirith Ungol, but since the film makers cut the half of the story which tells of Cirith Ungol to add into Return of the King, they had to have the second tower refer to Barad-dur.
Corrected entry: In the battle of Helm's Deep, why would the Uruk-Hai try so hard to storm the fortress gates when a huge section of the wall had just been blown up? That particular area wasn't being heavily defended.
Corrected entry: Just a small strategic moan, why would they have a long straight bridge/causeway up to the only weak point in the Hornburg's walls, i.e. the Gate, this just invites your foe to get a good run up with a battering ram, if they had either used a sharp turn or curve as they came up for a final approach to the gate, the orcs wouldn't be able to get the ram up to speed.
Corrected entry: Near the beginning of the film, Sam and Frodo are climbing down a hill. You can see that Frodo is at the bottom of the hill and Sam is near the top right handside of the hill. The shot changes and Sam is at the bottom of the hill with Frodo. That means Sam climbed down the hill in about 2 seconds.
Corrected entry: When Sam is cooking the rabbits, Gollum goes mad and shouts 'What's it doing? Stupid fat hobbit. You ruins it.' - to cook the rabbits, Sam must have skinned them, cut them up, made a fire and found water to cook the meat in. All that must have taken a fairly long time to do, so why is Gollum asking what Sam is doing with the rabbits NOW insted of before?
