6. Killing the cave troll. What sets this fight apart from all the others in the trilogy is Peter Jackson’s decision to make the troll a sympathetic enemy. Even though you know the troll has to die, you feel sorry for it, knowing it’s no more than a slave the orcs have abused and forced to do their dirty work. The Foley techniques used for the troll’s howls both pre and post its mortal wounding are crucial to making this the highlight of the first film for me. The scene also features Legolas’s first acrobatic move (running up the chain), some well-delivered lines from Sean Bean (“They have a cave troll!”) and John Rhys-Davies (“Let them come. There is one Dwarf yet in Moria who still draws breath!”), and the hobbits realizing they have to fight and kill to stay alive.
