Amidst all of the exciting recent casting news regarding Peter Jackson's upcoming prequel The Hobbit, which has seen quite a few Lord of the Rings alumni heading back to the Shire, including Elijah Wood, Cate Blanchett, Andy Serkis, Sir Ian McKellen, and possibly Orlando Bloom, another casting tidbit has flown under the radar. It appears that David Tennant, who will next be seen taking over the role of Peter Vincent, as originated by Roddy McDowall, in a Fright Night remake, has joined The Hobbit as Sindarin Elf King Thranduil.
Thranduil also happens to be Legolas' father, which sheds some light on how Orlando Bloom's character will be reintroduced to the franchise. Tennant also recently confirmed himself for a new take on Much Ado About Nothing, so it is not clear how he plans to fit both films into his upcoming schedule.
At this time, David Tennant's casting in The Hobbit has not been officially confirmed. David was originally being considered for the role of Bilbo Baggins, a part which has gone to Martin Freeman. Sylvester McCoy is also rumored to have been offered the role of Radagast the Brown, but there is no confirmation that he has accepted the role at this time either.
