The Ringwraiths uncloaked. We have seen this shot before...BUT...in this commercial, they are a lot blurrier. Very cool added effect. Later on, we see these same ringwraiths surrounding Frodo...but you might have missed it!

The light of Gandalf's staff temporarily holds the orcs at bay - right before the Balrog appears. They're surrounded by orcs, and are in a defensive huddle all facing outwards. From left to right: Gandalf, Boromir, Legolas, Gimli, Sam, Frodo, Pippin, Aragorn, Merry. (We saw this in the first FOTR Trailer)

Aragorn and Arwen about to kiss. (We saw this in the first FOTR Trailer)

THE LEGEND

While before we saw Arwen from the side as she carried Frodo to the Ford (replacing Glorfindel), now we see her from the front as she races away.

Legolas grabs an arrow and gets ready to fire back at the Moria orcs which are pursuing them.

Legolas takes aim.
