i can swear i recall that sauron did not cast the one ring of power to rule them all as the movie says. It was sauron's master...whos name i forgot:::the ring also enpowers sauron by alot but only makes other wearers invisible? why is this? and lastly,according to the movie, sauron was defeated when the ring came off. The book states that sauron only put a portion of himself in the ring, why is he destroyed when a finger is chopped off? he was after all, the most powerful being in the universe...
