The Lord of the Rings: The War of the Rohirrim is a 2024 anime fantasy film directed by Kenji Kamiyama from a screenplay by Jeffrey Addiss & Will Matthews and Phoebe Gittins & Arty Papageorgiou, based on characters created by J. R. R. Tolkien. Set around 200 years before Peter Jackson's The Lord of the Rings (2001–2003) and The Hobbit (2012–2014) film trilogies, it tells the story of legendary Rohan king Helm Hammerhand. When the neighboring Dunlendings propose a marriage to his daughter Héra, Helm unintentionally kills their leader in a fistfight and starts a war. The film stars Brian Cox as Helm and Gaia Wise as Héra, alongside Luke Pasqualino, Laurence Ubong Williams, Lorraine Ashbourne, and Miranda Otto. Presented by New Line Cinema, it was produced by Warner Bros. Animation and Sola Entertainment in association with WingNut Films and Domain Entertainment.
