Corrected entry: In the scene of Sam and Frodo on the slopes of Mount Doom, the entire scene has been flipped. Peter Jackson wanted the Hobbits to travel from left to right across the screen for all three movies, so the editors had to flip this scene to achieve that. This is also why any cuts/dirt smudges on their faces seem to change sides. Only when Frodo and Sam return to the Shire and go to the Grey Havens, do we see them traveling right to left.
Corrected entry: When Sam is fighting Shelob and stabs her in the eyes, there's gunk on Sting when he pulls it out - you can see it. But then, a shot later when Shelob throws Sting in the air, there's nothing on it.
Corrected entry: In the finale battle at the Black Gates, the good army is in a tight group surrounded by 10,000 orcs. If just 1/3 of those orcs had bows (which we never see in the final battle), and they volleyed into the group, 3000 men would have died right there (if not everyone, including Aragorn, Gandalf, the hobbits, etc). In all three films, the evil side has some sort of bowmen, but for some magical reason the army protecting the great eye and the orcs' leader, seems to have conveniently forgotten their bows. (Regardless of anyone's feelings, its a logical winning move for the orc, one that someone (PJ) left out, and no trees in Mordor to make bows is not a correction.)
Corrected entry: Sean Bean's contract was for all three films. That is why we see flashbacks of Boromir in this movie (Pippin remembering Boromir's death in Denethor's hall) and 'The Two Towers' (Boromir restraining Frodo at the Bridge of Khazad-Dum). In the Extended Editions, new footage of Boromir is seen in both films (Denethor hallucinating a vision of Boromir in this film and Boromir commanding his troops at Osgiliath in 'The Two Towers').Blibbetyblip
Corrected entry: When Eowyn faces the Nazgul in combat, he once swings his morning-star horizontally. In the instant where the scene is shown from behind the Witch King, Eowyn dodges the weapon's had by leaning backwards; but then, as the same scene is shown from behind Eowyn, she suddenly ducks low to avoid it.
Corrected entry: One look at the palantír is enough to make Pippin irresistibly drawn to it. When he steals it from Gandalf Merry takes quite a good look at it to and even looks into it while Pippin does. Merry should have been drawn to it just the same as Pippin, it's not something they could control.
Corrected entry: The parting of Merry and Pippin takes place within two or three days after the Isengard battle. In the aftermath of Isengard they find one barrel each filled with pipeweed, yet when Merry says goodbye to Pippin all that is left is a small pouch. There is no way they could have smoked all that pipe weed in just a few days; it was month's worth.
Corrected entry: When the title shows, we see a shot moving to a flooded Isengard. If you look closely, you can see Merry and Pippin sitting on the wall; Pippin on the left and Merry on the right. But when in the close-up of the two of them, Merry is now on the left and Pippin is on the right. (00:10:00)
