Вот интересную штуку услышал у Easy Allies. Во «Властелине колец» (и «Хоббите») говорят о том, что Саурон возрождается и набирает силу. При этом в книгах, по сути, нет упоминаний о том, что Саурон уже принял физическую форму, в отличие от фильма, где он показан в виде огненного глаза. В книжках это скорее некий образ, который внушается смотрящему.
Канонический глаз из фильма, например, видит Фродо, когда смотрит в зеркало Галадриэль (момент есть в фильме):
But suddenly the Mirror went altogether dark, as dark as if a hole had opened in the world of sight, and Frodo looked into emptiness. In the black abyss there appeared a single Eye that slowly grew, until it filled nearly all the Mirror. So terrible was it that Frodo stood rooted, unable to cry out or to withdraw his gaze. The Eye was rimmed with fire, but was itself glazed, yellow as a cat’s, watchful and intent, and the black slit of its pupil opened on a pit, a window into nothing.
Then the Eye began to rove, searching this way and that; and Frodo knew with certainty and horror that among the many things that it sought he himself was one. But he also knew that it could not see him — not yet, not unless he willed it. The Ring that hung upon its chain about his neck grew heavy, heavier than a great stone, and his head was dragged downwards. The Mirror seemed to be growing hot and curls of steam were rising from the water. He was slipping forward.
Примерно такое же видит Фродо каждый раз, когда пользуется кольцом (в т.ч. в сцене, когда пытается скрыться от Боромира):
And suddenly he felt the Eye. There was an eye in the Dark Tower that did not sleep. He knew that it had become aware of his gaze. A fierce eager will was there. It leaped towards him; almost like a finger he felt it, searching for him. Very soon it would nail him down, know just exactly where he was. Amon Lhaw it touched. It glanced upon Tol Brandir — he threw himself from the seat, crouching, covering his head with his grey hood.
Тем не менее, про физическую форму Саурона есть намек в книгах. Солдаты армии Сарумана носят на форме красный глаз и белый знак четырехпалой руки :
He it was that now rode out, and with him came only a small company of black-harnessed soldiery, and a single banner, black but bearing on it in red the Evil Eye. Now halting a few paces before the Captains of the West he looked them up and down and laughed.
А про отрубленный палец мы все знаем (см. первую сцену фильма):
‘That would be Minas Ithil that Isildur the son of Elendil built,’ said Frodo. ‘It was Isildur who cut off the finger of the Enemy.’
‘Yes, He has only four on the Black Hand, but they are enough,’ said Gollum shuddering. ‘And He hated Isildur’s city.’
‘What does he not hate?’ said Frodo. ‘But what has the Tower of the Moon to do with us?’
