Elessar, the bit where Aragorn knels before the hobbits (Frodo and Sam) is one of my favourite bits in the books, and my favourite scene in the Films. I must admit I cried like a baby the first time I saw it on screen, and it still brings a tear to my eye on the umpteenth viewing.
PS I stated this before on another thread, but if the Elves were at Helm's Deep fighting with Men, why didn't Galadriel call the fight at Mount Doom at the start of FOTR The Penultimate Alliance!!!
