Maybe he's thinking of Aragorn confronting Sauron through the palantir. I think I read that that's shown in the extended edition of the ROTK, which I haven't watched yet.
I haven't been able to read any of the books as they are so long winded :yawn: but the films are OK. I do agree with ythe fact they are overhyped as I have seen many fims better that LOTR.
