The films obviously portray Sauron as confined to the form of lidless eye. But did Tolkien intend for this to be just a metaphor for his near-omniscience? Did Sauron in fact have a body during the third age? And if so, why didn't he come forth to lead the war effort himself? I like to imagine, if he was weakened by the loss of the ring, he might have conducted himself like the Almighty in the (admittedly awful) film 10,000 BC: this frail ruler, waited on hand and foot by his servants, exercising power from behind the scenes: Or maybe this would be more analogous to the Black Numenoreans ruling over the Haradrim. What do you think?
