Lord OF the Ring 2 Trivia
Near the end of the first movie, in the scene where Aragorn fights the Uruk-hai Captain Lurtz, Aragorn uses his sword to deflect his Elvish dagger, which Lurtz threw at him after he stabbed him in the leg with it. This was not meant to happen as in the original script the knife was supposed to miss and hit the tree behind Aragorn, though the mask Lurtz's actor was wearing restricted his vision, causing him to miss his mark and throw the knife directly at Aragorn. Luckily he was able to use his sword to deflect the knife just in time. The director decided to keep that scene rather than the originally planned scene, as he did just barely manage to knock the dagger away.
