Get ready to return to Middle-earth, anime-style, as Warner Bros. and New Line Cinema have shared the trailer for The Lord of the Rings: The War of the Rohirrim, an animated feature from director Kenji Kamiyama (Blade Runner: Black Lotus) and “presented” by Peter Jackson.

Narrated by Miranda Otto, reprising her role as Eowyn from Jackson’s The Lord of the Rings trilogy, the voice cast features Brian Cox as Helm Hammerhand, the mighty King of Rohan, Gaia Wise as his daughter Héra and Luke Pasqualino  as Wulf alongside Lorraine Ashbourne, Yazdan Qafouri, Benjamin Wainwright, Laurence Ubong Williams, Shaun Dooley, Michael Wildman, Jude Akuwudike, Bilal Hasna and Janine Duvitski. Watch the trailer below…

Set 183 years before the events chronicled in the original trilogy of films, “The Lord of the Rings: The War of the Rohirrim” tells the fate of the House of Helm Hammerhand, the legendary King of Rohan. A sudden attack by Wulf, a clever and ruthless Dunlending lord seeking vengeance for the death of his father, forces Helm and his people to make a daring last stand in the ancient stronghold of the Hornburg—a mighty fortress that will later come to be known as Helm’s Deep. Finding herself in an increasingly desperate situation, Héra, the daughter of Helm, must summon the will to lead the resistance against a deadly enemy intent on their total destruction.

The Lord of the Rings: The War of the Rohirrim will ride into cinemas on December 13th.
