Even though I only answer Logical and Possible Questions, I just had to join in on this one

. I think, even if a director was given the rights to film this movie, I do not see how he could possibly film thousands of years of the Making of Middle Earth, and all that happened before the Hobbit and beyond. They would have to include all of the characters mentioned in the Lord of the Rings and the Hobbit alike, telling of how they came to be, and how. The Silmarillion is almost impossible to film. And even if they
somehow were able to film this, they would have to break it down into nearly 2 Parts or more. Plus, for all the money it would take to hire all the actors, Film, and Computer Animation, and many other needs, I do not think they would even get a profit, if not a deficit from this Movie. First of all, many people would not know much of what the Silmarillion is about except those very interested in Tolkien's work. Second of all, even if some did know of what it was, there is not as much action (Fighting) as there is in ROTK, and The Two Towers. Many people who do not appreciate Tolkien would not be impressed, thus creating a bad review, insulting Tolkien on one of his most Prized Book. And there is not a Law Suit on this for no reason, it is one of the Hardest Books to film. So, I would not even recommend trying to come out with a Movie based on the Silmarillion.
Best Wishes,
