That's what I thought at first too, but on my second, third, fourth looks the orcs are marching under the Red Eye, not the White Hand. As far as I know only Saruman sent orcs to Helm's Deep. I was thinking it might be footage of Sauron's attack on Minas Tirith.
I am enchanted by this shot, of Frodo and Sam still in the Shire, watching the elves passing through to the Grey Havens, never to return... How cool is that!?
That is very cool. ;^)
hmmm.... Do I have to watch it again? ;~D
