Technically only LOTR and the Hobbit were written by Tolkien and everything else with his name on it was only partially written by him to a greater or lessor degree and revised/expanded on by his son.
Sorry, but the Silmarillion was written by him. It was published posthumously, but it was written by him. Christopher Tolkien only provides interspersed commentary. :hatsoff:
from wikipedia said:Due to Christopher's extensive explanations (in The History of Middle-earth) of how he compiled the published work, much of The Silmarillion has been debated by readers. Christopher's task is generally accepted as very difficult given the state of his father's texts at the time of his death: some critical texts were no longer in the Tolkien family's possession, and... many divergent ideas which do not agree with the published version. Christopher Tolkien has suggested that, had he taken more time and had access to all the texts, he might have produced a substantially different work...Some contend that parts of The Silmarillion are more a product of the son than of the father, and as such its place in the Middle-earth canon is hotly debated in certain circles.
There is much that Tolkien intended to revise but only sketched out in notes, and some new texts surfaced after the publication of The Silmarillion. These...also make it clear just how unfinished the later parts of The Silmarillion really were: some parts were never rewritten after the early versions in Lost Tales.
There is only one LOTR which has been written and shot on film. So there isn't anything else to do on this matter.
I don't think its been done because his family still own the rights etc and they aren't (YET) going to sell the rights to some hack for his fan fiction attempts. Its big shoes to fill, the fantasy equivalent of trying to sequel dostoyevsky.
Well, the money-sucking leeches will be making two movies out of "The Hobbit". Never mind that it's a book shorter than any of the "rings" trilogy.
I was so looking forward to "The Hobbit" as a movie made by the same folks who did the LOTR trilogy, until I'd read that they are going to make two long movies out of it. I would think you could make a really good, maybe even great two and a half hour movie out of "Hobbit".
Even then both those people were alive when a lot of it was done and were more or less excepting of it. That can’t really be the case with Tolkien.
