The Silmarillion is probably the one that'd have been more interesting to me since I've always felt that Tolkein was a better world builder than story teller from what I've read of his work. That said, I won't be particularly sad if Jackson doesn't get to make more movies because while I liked the LotR trilogy, the Hobbit movies are pretty bad on many levels. Only real thing I like about them is getting to watch Martin Freeman and Ian McKellan on screen. The rest of it is bleh.
