Critics and fans around the world will all agree: The Lord of the Rings trilogy by Peter Jackson is a timeless masterpiece. However, we managed to find 13 small mistakes and inconsistencies within the movies that you might have missed.
In The Fellowship of the Ring, when "Gandalf" rolls into Hobbiton on his cart for "Bilbo’s" birthday celebration, you can see the lights of a plane above the hobbit huts.
In many of "Frodo’s" fight scenes with the Orks, like in the mines of Moria, his sword "Sting" does not light up blue although it is supposed to do just that as soon as Orks are close.
The seal on the envelope in which "Bilbo" put the ring for "Frodo" seems to change multiple times. It becomes apparent in the scene when "Gandalf" closes and seals the envelope, but when he hands the envelope to "Frodo", the seal looks totally different.
Right before the final and deciding battle at the Black Gate, the armies from Gondor and Rohan are mostly on horseback. As soon as the battle starts, there are no horses anywhere.
In one scene inside Theoden of Rohan’s throne room, the length of "Aragorn’s" facial hair does vary quite a bit from shot to shot.
As they are fleeing from the Nazgul, "Arwen" rides into the river with "Frodo" sitting in front of her, yet it is quite clear Elijah Wood has been replaced by a dummy. Especially because the person sitting in front of "Arwen" does not have the Hobbit's hairy feet...
"Frodo" is hurt and needs to be lifted onto "Arwen’s" horse. As "Aragorn" picks him up, it becomes apparent that he’s not helping his fellow cast member Elijah Wood getting up on the horse but rather a stand-in, probably a child due to the proportions.
While the Fellowship wanders through the mines of Moria, "Gandalf" uses his glowing staff to lead them through the darkness. Unfortunately, we can see the cord which is used to power the staff. The lamp used as the light on top of the staff had such a high energy consumption that it could not be powered by a battery.
In Rivendell, while "Elrond" explains to the Fellowship what their mission is going to be, there are a couple of close-ups on the ring, in which we are able to see the film set and its surroundings.
The length of the chain on which Frodo carries the ring until "the end of all things" seems to vary on multiple occasions throughout all three films, to whatever suits the particular situation best...
Since the elf "Legolas" has piercing blue eyes, Orlando Bloom, who has brown eyes, had to wear blue contact lenses while shooting the films. These contacts really didn't sit well with him and he couldn’t wear them all the time, so the color of his eyes was digitally altered in post-production. But when "Legolas" is looking at the Crebrain birds in Dunland, one notices that the alterations were forgotten and he has his (natural) brown eyes.
In his fight against "Saruman" (Christopher Lee) inside the tower of Orthanc, "Gandalf" (Ian McKellen) suffers a blow to the forehead and starts to bleed from a cut, which disappears in the following shot, only to reappear in the next.
The wizard’s horse "Shadowfax" was portrayed by – at least – two different horses during the shoot. It becomes clear when you look at the horse’s blaze and the legs.
