That answer is a cheat, Aethelwine - avoiding the question!
However, I agree - I don't think they should make a film of The Hobbit either. For my part, this is partly because it was one of the first fantasy books I ever read, and so to have it made through someone else's mind could go very wrong - it wouldn't seem quite right, when I have such a vivid image. Also, on the part of the general public, I don't think it would actually be as popular - maybe people would go to see it out of pure curiousity, and the die-hard middle earth fans would be bound to, but come on, the main characters are dwarves - and, no offence to them and this isn't necessarily my personal opinion, but they are hardly the most glamourous or particularly engaging of the races of Middle Earth, as the LotR films showed.
