Its very premature. I mean we have an incredible source material with the appendices because The Hobbit is obviously a novel but we also have the rights to use this 125 pages of additional notes where Tolkien expanded the world of The Hobbit published at the end of Return of the King and weve used some of it so far and just in the last few weeks as weve been wrapping up the shooting and thinking about the shape of the story, Fran and I have been talking to the studio about other things we havent been able to shoot and seeing if we persuade them to do a few more weeks of shooting, probably more than a few weeks actually, next year. And what form that would actually end up taking, well the discussions are pretty early. So there isnt really anything to report but theres other parts of the story that wed like to tell that we havent been able to tell yet.Weve used more source material than The Hobbit. For instance in The Hobbit when Gandalf mysteriously disappears for chapters, it was never really explained where hes gone. Much later Tolkien filled in those details. In these appendices he did talk about what happened. And it was all together a lot darker and more serious than what is written in The Hobbit. And also to be honest I want to make a series of movies that run together so if any crazy lunatic wants to watch them all in a row there will be a consistency to it, a consistency of tone.So I dont want to make a childrens story to go into The Lord of the Rings so we are providing a balance. I mean a lot of the comedy and the charm comes from the characters. Youre dealing with Bilbo Baggins who is a bit more reluctant to go on an adventure than Frodo was and with Dwarves who have a personality and camaraderie all of their own, so theres a lot of humor but there are still some serious themes involved.
