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.

With Kamiyama at the helm, the original feature is being produced by Oscar winner Philippa Boyens, from the screenwriting team behind “The Lord of the Rings” and “The Hobbit” Trilogies, alongside Jason DeMarco and Joseph Chou, who, in addition to their many separate animation projects, collaborated on the “Blade Runner: Black Lotus” series. The executive producers are Fran Walsh, Peter Jackson, Sam Register, Carolyn Blackwood and Toby Emmerich. The screenplay is by Jeffrey Addiss & Will Matthews and Phoebe Gittins & Arty Papageorgiou, story by Addiss & Matthews and Boyens, based on characters created by J.R.R. Tolkien. The team of creative collaborators returning from “The Lord of the Rings” Trilogy also includes Oscar winners Alan Lee and Richard Taylor, along with esteemed Tolkien illustrator John Howe.
