Peter Jackson in an interview with AP News Service. said he’d be happy to direct a movie based on Tolkien’s original work, “The Hobbit”.
“It would be strange for somebody else to do it. And I also think to do justice to THE HOBBIT it would be great to bring some of the same actors back. I think it would be a cool thing to have the continuity of the design and the look and feel of the world and use whatever actors we’re able to repeat in the story.”
He has however said that he hasn’t been approached to do the film, and mentioned complicated book rights as being a significant factor.
