[Galadriel55]

You are probably right, Pitchwife, but for some reason I always thought that Sauron needed the Ring to get back the power to create a body for himself. I don't trust the movies one jot; that idea of mine came from the books. A long time ago I decided for myself that Gollum didn't really see Sauron's body. According to me what really happened is that what remained of Sauron's power and will was still so great, that Gollum saw a vision of how Sauron would look like when he was brought before him. Since the missing finger was a big part of who Sauron is (cause he wore the Ring on it, etc), Gollum would have seen only 9 fingers. Sauron's Eye doesn't really exist, like it does in the movie. It is Frodo's metaphor for Sauron's power when he's searching, because that is when Frodo felt it most before he came close to Mordor.
