The Lord of the Rings: The War of the Rohirrim is a fascinating experiment in adaptation. It's not adapting a novel of J.R.R. Tolkien's, but rather two pages from his Appendices, which lay out the last great stand of one of Rohan's most famed kings, Helm Hammerhand (voiced by Succession 's Brian Cox ).

The War of the Rohirrim" is a unique shift from traditional Middle-earth media. It's been decades since we got a Middle-earth adaptation in animated form. (You've got to go back to the '70s and '80s for those sub-par old Ralph Bakshi and Rankin/Bass "Lord of the Rings" and "Hobbit" adaptations to find something similar.

The War of the Rohirrim is set to revisit the early days of Middle-earth while also marking Peter Jackson's return to the iconic fantasy franchise based on J.R.R. Tolkien's novels (though Jackson is serving in a producer category).
