Apparently
Warner Bros. is set to produce new adaptations based on Tolkien's universe. If I understand correctly, they are not looking into re-making LOTR or the Hobbit, although they have the rights to these books as well, but will explore other aspects of the
"the vast, complex and dazzling universe dreamed up by J.R.R. Tolkien". They don't go into further details yet, but I guess this means the Silmarillion etc.? It is strange that, if this is indeed the case, they didn't mention it specifically. But what else could it be?
