On their way to the pass of Cirith Ungol, Sam looks backward -- at Gollum?

Sam looks rightfully distrustful and apprehensive.

Theoden with Gamling by his side, reacts in shock to some unknown news -- has he received the Red Arrow of Gondor?

Has Theoden received the Red Arrow of Gondor? Or does he fear for Aragorn's journey on the Paths of the Dead?

The troops of Rohan muster following the battle of Helm's Deep. Could this be the site of Orthanc? Notice the river streaming down the mountainside, and... could those be Huorns!?!?

The Rohirrim prepare to ride to the aid of Minas Tirith, as trees lurk in the background. If they aren't Huorns, where did they come from?

Eomer, Legolas, Gimli and Theoden lead the way.

The path is long, will they arrive in time?

The vast gates of Minas Tirith swing open as horses ride in to the main courtyard of the city (as per this still from the video).

The history of Gondor graces the the gates, as you can spy one of the main courtyards of Minas Tirith within.
