The more important question in my mind is how come in TTT it takes two trolls to open the gate, but in ROTK it opens by itself? Is Sauron using the Dark side of the Force to open it from across Mordor?
Speaking of the Force you can see Gandalf using the Force on Aragorn. That part where you hear the Eye going "Aragorn..." the camera cuts to Gandalf for a second and you can see him wave his hand like he's using the Force.
