Apologies if this has been posted already, I did scan through the last six pages or so. Anyways, for those waiting to see what the Orc Forge looked like, here it is (found in the SW 2012 thread, taken by member "Sir von Lego"):

I don't understand why they chose to turn such an insignificant scene into a set, but I think it looks quite good. Of course the CGI does help with this, but I think it captures the feel of the movie very well. It's actually quite interesting, I feel like the quality of TLG's sets have recently moved towards MOC quality, we wouldn't have seen things like the brickbuilt rock base before. EDIT: Megablock you LEGOman273, I type too slowly.
