"The Hobbit: An Unexpected Journey" Trailer with Comments
Just found this online courtesy of TOR books, and here's the YouTube video...
It looks cool. The Dwarven songs in which they mourn for the loss of their homeland to the dragon Smaug are nice. We don't really see a lot of Dwarf culture in the three Lord of the Rings films beyond them living underground and favoring feasting and axes, so this is nice.
One quibble--Thorin Oakenshield looks too human. He's too tall and slender for a Dwarf. I remember hearing that there had been some kind of Twilight-induced attempt to make the Dwarves "sexy," although all I could find was this article here.
I'm wondering how they work Rivendell and Galadriel into the story. Gandalf and the White Council were active at the time in order to prepare the Free Peoples for the return of Sauron--who at this point was operating under the guise of the Necromancer of Dol Guldur--but I don't think the council dealt with him until well after the events of The Hobbit.
A thought I had was that they might work the White Council's defeat of disguised-Sauron into these two films somehow and have them physically destroy the Necromancer. He would not be killed, since his essence is bound to the One Ring, but this could explain why Saruman told Gandalf in the first film that "he cannot yet take physical form."
