Ah, a general overview! That's a good job taking it to 7 hours! And I think they could many MANY films from Tolkien's material, right down to the story of Aldarion and Erendis...
Cheers and welcome to the Downs!

P.S. If you want to see dangerous Tolkien geekery, head to the old
Canonicity thread in the Books forum. Lots of opinions and nothing really gets solved. But I think there is not a problem to be solved, just a delightful otherworld to get lost in! And I don't think I'll revisit the Balrog question!
