Do the movie rights have a shelf life? Book copyright expires eventually though there are ways to extend it so surely you can't have film rights in perpetuity? I am sure there will be a Hobbit film sometime but I really wish that it wouldn't involve Jackson. They are reshowing the films on TV at the moment and I have watched bits (somehow can never quite settle to rewatch all the way through) and while I fully admit that they aren't at their best on a midsize domestic screen, the CGI hasn't aged well IMO. And I still can't see Jackson's elves, Gollum or even dwarves translating particularly well or McKellen's Gandalf. He paints with too broad a brush... So I woud hope for some combination of circumstances that would mean that someone else got a free hand. But I suppose they have gone so far with Jackson...
