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.
