Continuity mistake: There's a close-up of Frodo's face after the camera shows the stone Trolls, and Frodo's face is shining with sweat. Then Sam says, "Look Frodo, it's Mr. Bilbo's Trolls," and there's a shot farther away from Frodo's face. In this shot, Frodo's face has no signs of sweat on it. Extended DvD. (01:14:40)
Continuity mistake: 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. (01:15:30 - 01:16:35)
Continuity mistake: At the battle on Amon Hen, Strider falls back and lets an Uruk Hai fall into his sword. In the next shot you´ll see Strider drawing his sword from the Uruk between his arm and his chest (seen on the left side of the scene). (01:16:13)
Continuity mistake: After Frodo runs from Boromir, invisible and wearing the Ring on his right hand, he sees the Eye. As he starts to fall, with his left hand he pulls the Ring off the finger of his right hand. Yet, in the next shot still falling, now visible, we see his right hand closed in a fist and when he lands on the ground, he's clutching the Ring in his right hand. (01:16:50)
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. (01:17:25)
Continuity mistake: 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. (01:17:30)
Continuity mistake: When Aragorn speaks with Frodo near the stairs at Amon Hen, the greenery sticking out of the indivial steps in these shots differ and actually change their position on the stairs significantly, after Aragorn yells, "Run!" and then walks toward the many Uruk-hai. (01:17:50 - 01:18:30)
Continuity mistake: When Arwen is carrying Frodo to the Ford, during the close-up of his face, it is covered in a green slime/pus-type substance (coming out of his eyes and mouth). At the Ford when Arwen confronts the Black Riders, his face is clean. [Peter Jackson has stated that the pus was used in one scene and afterwards they decided it was too gross and didn't use it again. That's why it appears and disappears. Still a mistake though.] (01:18:15)
Continuity mistake: During the battle at Amon Hen, Legolas says, "The Horn of Gondor!" Aragorn then rushes past him so close that he has to lean backwards to let him pass. In the next wide shot, Aragorn runs past Legolas again but this time further apart. (01:18:20)
Continuity mistake: During the end fight scene with the Uruk-hai, the fight scene takes place on the side of a hill for the most part, but you can see that sometimes the sunlight shines down the hill and sometimes it shines across the hill, meaning it was filmed at different times of the day. (01:18:50)
Continuity mistake: When the Nazgul confront Arwen across the river, they draw their swords in their left hands. In the next shot this changes to their right. (01:19:10)
Continuity mistake: When Gandalf and Elrond are talking about Frodo and his ability to withstand the power of the Ring, when the camera is in wide view you can see Gandalf holding his pipe in his hand with the stem near his chin, when the camera angle changes to a close up view of Gandalf the stem is nowhere to been seen. It happens about 4 times during the entire scene as the camera angle changes. (01:19:21)
Continuity mistake: At Amon Hen while battling the Uruk-hai, Legolas yells to Aragorn, "Aragorn, go." In the next far wide shot, we see Aragorn run between the statue and Legolas, reaching the pillar. In the very next close-up, Aragorn is just running past the statue on his left, as Legolas kills two Uruks with one arrow. (01:19:25)
Continuity mistake: 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. (01:19:35)
Continuity mistake: After Arwen has crossed the Ford of Bruinen and is challenged by the Ringwraith Witch-King, she draws her sword and holds it high and ready to strike. Arwen then calls upon the waters of the river for assistance. When the rush of water with horses' heads comes around the bend and into view there is a clear shot of Arwen's back as she is watching the water come down on the Ringwraiths and she is not holding her sword up. Shortly after all the Ringwraith's are swept away, there is a scene of Arwen's face and upper body and she is still holding the sword high and ready to strike. (01:19:40)
Continuity mistake: At Amon Hen, when Merry and Pippin realize that Frodo needs to leave, they start jumping up and down and shouting to get the attention of the Uruk-hai. While they jump up and down, in the back shot, Pippin is behind Merry, but in the front shot, Pippin is in front of Merry. (01:20:20)
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. (01:20:55)
Continuity mistake: After diverting the Uruk-hai at Amon Hen, Pippin and Merry run. Just before Boromir comes to their rescue, in the far shot, they are seen running over a stone bridge and Pippin is in front of Merry. In the very next close-up, Merry is running in front of Pippin. (01:20:55)
Continuity mistake: When Arwen is being chased on horseback through the woods by the Ringwraiths, at one point her face gets grazed by a tree branch, which leaves a long red scratch on her right cheek. In the following shot from up behind the horse she's riding, when she turns around one more time to see where the Wraiths are, her face is conspicuously unblemished, only to have the scratch re"surfaced" on subsequent close-ups. Also, during this long flight to the Ford sequence it is quite discernible in many cuts by cueing on her face (esp'ly in slo-mo) that the rider is a stunt double. (01:21:10)
Continuity mistake: At the end of the Amon Hen battle scene, where Boromir has been shot by Lurtz, there is a close-up of Lurtz's feet (as if from Boromir's POV) showing Lurtz striding over and stopping in front of him. The ground is clear all around his feet. The shot then changes to a wide shot, from the side, and there are orc corpses piled up all around. None of these were visible before, but should have been. (01:21:20)
Answer: "Fly, you fools"
