Richard Armitage...Yes, again. Video. You can see the development here, of Thorin's look. Took 5 tries. That's why he looks different at the beginning of the film. He looks different when he sings than in Erebor.
I really enjoy the extended editions of The Lord of the Rings, but that’s because while, yes, the theatrical versions of those films were long, they weren’t overlong like The Hobbit. So when those films were extended it felt fun and new and adding geeky details to a well trimmed and timed set of films. What we have here looks to me like adding more bloat to the bloat we already saw in the theater.
