The Extended Edition of The Hobbit: An Unexpected Journey was shown in-flight on Air New Zealand. Fortysixthhour on Tumblr was kind enough to report on 12 of the new scenes. Avoid if you do not want spoilers. There will be more fun with dwarves being mischievous, elves being offended, goblins singing horribly, young Bilbo, and most importantly IMO, impending dragon sickness in the line of Durin.
I am wondering where the scenes of Thrain and Girion have gone, since these were originally stated to have been included in the EE. I am hoping these have instead made it into The Desolation of Smaug theatrical release.
