If you haven’t noticed, Helms Deep is currently the centre of all the action. My contacts tell me this set will be used for weeks more, and it’ll be the centre of most of the action in the movie as well. Ringer Spy Blinky fills us in on what they’ve been filming for the past couple of days.
Looks like they are now filming up at the top of the hill, where there appears to be a turret of some kind. The bottom of the hill, where there is the exterior of the castle, with a entrance/drawbridge thing is no longer being lit.
