In the official ROTK photo guide that is available here, I read something very strange: Arwen is ill and dying, and that's why she sends Elrond to bring Andúril to Aragorn! It sounded like a really weird plot change, and I really wonder why PJ put that in. It would explain the famous unexplained picture of Arwen lying on that bed as if sleeping.
'But this I will say to you, Celegorn the fell, by the sight that is given me in this hour, that neither thou nor any son of Fëanor shall regain the Silmarils ever unto world's end. And this that we now seek shall come indeed, but never to your hands. Nay, your oath shall devour you, and deliver into other keeping the bride-price of Lúthien.'
