The upcoming anime film, The Lord of the Rings: The War of the Rohirrim, will explore the legend of Helm Hammerhand and the history of Rohan, with Peter Jackson returning as Executive Producer and Philippa Boyens involved as a producer and story consultant. Directed by Kenji Kamiyama, the film is anticipated to blend familiar elements of Tolkien's lore with new characters and plotlines, showcasing the struggles against the Dunlendings and the founding of Helm's Deep. Miranda Otto will reprise her role as Éowyn, narrating the tale, which connects her character to the story of Hera, a new figure in the narrative. Despite some purist concerns regarding liberties taken with the source material, the film promises high-stakes battles and political intrigue, as highlighted in its recent trailer. The film's release marks the first animated entry in over 40 years, potentially paving the way for more adaptations in various styles. The trailer also introduces new elements, like the Watcher in the Water, which adds to the excitement surrounding this new chapter in the franchise.
