"Those who listened unwarily to that voice could seldom report the words that they heard; and if they did, they wondered, for little power remained in them. Mostly they remembered only that it was a delight to hear the voice speaking, all that it said seemed wise and reasonable, and the desire awoke in them by swift agreement to seem wise themselves."
-The Voice of Saruman
I love the idea of words having power. In The Two Towers and later in Return of the King, Saruman's voice never loses its full effect even after his staff is broken. The voice of Saruman becomes something more than the man, almost its own character. I wanted to illustrate this concept by removing Saruman from the scene altogether so that it's just his voice filling the space in front of Orthanc.
