Adapting The Lord of the Rings presented a million little challenges. While Peter Jackson did an incredible job with the original trilogy, the franchise continues to carry on with less impressive source material. Tolkien has a lot of appendices that offer additional details and helpful background. There are plenty of high-quality stories buried in that endless text, but most of them are a bit sparse. The upcoming War of the Rohirrim anime film will adapt one such example. The film will adjust the original tale to upgrade the newly-named daughter Hera from a plot-relevant object to the main character.
