Set 183 years before the events of the original film trilogy, The Lord of the Rings: The War of the Rohirrim is the first Lord of the Rings anime and we finally have a full trailer. The film tells the fate of the legendary King of Rohan, Helm Hammerhand, and how his daughter, Héra led a great resistance against a deadly enemy.The trailer, which was teased earlier Thursday by Warner Bros., gives Lord of the Rings fans their first look at Héra in action and the mystery of the whereabouts of the rings. Check it out below. Directed by iconic anime director Kenji Kamiyama, the voice cast includes Brian Cox as Helm Hammerhand and Gaia Wise (A Walk in the Woods) as Héra. They’re joined by Luke Pasqualino (Snowpiercer) as Wulf with Miranda Otto reprising her role as Éowyn, Shieldmaiden of Rohan, serving as the tale’s narrator.Flanking Kamiyama, the film is produced by Oscar winner Philippa Boyens, from the screenwriting team behind both The Lord of the Rings and The Hobbit features. She is joined by Jason DeMarco and Joseph Chou, who collaborated with Kamiyama on the Blade Runner: Black Lotus series. Peter Jackson and Fran Walsh jumped on as executive producers of the project back in June, reuniting the trio of the original films. However, before fans can join Héra on her adventure, Prime Video’s The Lord of Rings: The Rings of Power arrives in September for his sophomore season. After both of these, we’ll get Peter Jackson and Andy Serkis’ return to Middle-earth with The Lord of the Rings: The Hunt for Gollum.The Lord of the Rings: The War of the Rohirrim is set to be released in theaters on December 13. That’s right around the time of year when the original Lord of the Rings trilogy, as well as the Hobbit movies that followed, were released. This will be the first Lord of the Rings movie in theaters in a decade.
