"Ten years ago, Orlando Bloom created an iconic character with his portrayal of Legolas. I'm excited to announce today that we'll be revisiting Middle Earth with him once more," Jackson wrote on his Facebook page. "I'm thrilled to be working with Orlando again. Funny thing is, I look older—and he doesn't! I guess that's why he makes such a wonderful elf."
Although Legolas the elf is a main character in J.R.R. Tolkien's Lord of the Rings book trilogy and the big-screen adaptations, he doesn't actually appear in The Hobbit novel.
The upcoming two-part Lord of the Rings prequel will feature original cast members Cate Blanchett, Sir Ian McKellen, Andy Serkis, Elijah Wood, Hugo Weaving and Ian Holm, who are all reprising their roles. Stephen Fry has also joined as the Master of Laketown.
The Hobbit is slated for release in December 2012 and then December 2013.
