Bonus material from The Hobbit: The Desolation of Smaug. This is a truly amazing documentary. The incredible detail and level of craftsmanship that went into these movies in awe-inspiring and kind of fabulously crazy... I particularly loves the work done by the costumers and set crafters and dressers...coopers, glassblowers,carvers, weavers and so many more. ;-) 5 hours of awesome documentary.
