It's now official: The Lord of the Rings screenwriting team of Peter Jackson (pictured), Fran Walsh, and Philippa Boyens will join The Hobbit director Guillermo del Toro to pen the screenplay for the two planned Hobbit movies. Sources tell EW.com that the scribes' deals are all complete and they have already begun writing. (With shooting scheduled to begin Fall 2009, at the earliest, in New Zealand, the quartet better get busy!) The Hobbit will center on Frodo's uncle, Bilbo Baggins, and his initial discovery of the immensely-powerful ring. New Line and MGM plan to release the two films Christmas 2011 and Christmas 2012.
