Martin Freeman has been on board since day 1 and former Doctor Who Sylvester Mccoy also having a role. Frodo himself Elijah Wool has also signed which is something of a mystery as Frodo is never mentioned in The Hobbit, what with this being a prequel to the Rings Trilogy, clearly Jackson is taking some artistic license.
The film has had a troubled pre-production with copyright issues stopping production for many years, and a loss of original director, but with Jackson on board and the continuing cast list 2012 will be a great year for fans of the Tolkien world.
