Orthanc -- Saruman’s tower-- and the second of the film’s namesake.

Orthanc again - is that an orc overseer/pit worker with a curved weapon standing on the outer wall of Isengard in the foreground?

Grima’s and his true master, Saruman.

Saruman’s Uruk-Hai army waiting to begin their assault on Helms Deep.

More of the same… probably.

Legolas and Aragorn on the parapets looking out at the Orc horde; elvish bowmen from Lorien (?) accompany in background.

Is this the scene on the Deeping Wall before the battle?

Could this be Frodo and Sam making their way through the Dead Marshes? Look out for the Rodents of Unusual Size!

Frodo Baggins in the Dead Marshes.

Samwise Gamgee in the Dead Marshes.
