According to Digitalspy.co.uk Scottish actor Brian Cox could be cast for a role as a dwarf in The Hobbit movie, which would be simply amazing. I could see him playing Thorin Oakenshield, as Tolkien himself putted :"An enormously important dwarf." I think casting is taking longer of many fans expected as it must not be easy to cast 13 dwarfs, nevertheless I have a good feeling about this, we are getting closer to finally find out. More news as they reach me here in the Shire. Stay tuned hobbits.
"It was a dwarf with a blue beard tucked into a golden belt, very bright eyes under his dark-green hood. As soon as the door was opened, he pushed inside, just as if he had been expected."
(J.R.R.Tolkien - The Hobbit)
