The Warner Bros. animated Middle-earth production, The War of the Rohirrim, is set to debut on screen on April 12, 2024.

The feature-length film is set to focus on the story of the Rohirrim king, Helm Hammerhand, as outlined in Appendix A of The Lord of the Rings.

Warner Bros. says that it will “explore… the untold story behind the fortress of Helm’s Deep, delving into the life and bloodsoaked times of one of Middle-earth’s most legendary figures; the mighty King of Rohan — Helm Hammerhand.”

Acclaimed filmmaker Kenji Kamiyama (especially known in anime circles for his work on Ghost in the Shell: Stand Alone Complex) is directing, while Philippa Boyens (co-screenwriter for Peter Jackson’s Lord of the Rings and The Hobbit) is executive producer.

The writing team of Phoebe Gittins and Arty Papageorgiou have penned the screenplay based on a script from Jeffrey Addiss & Will Matthews. The “Lord of the Rings” returning creative team also includes Oscar winner Richard Taylor and Tolkien illustrator John Howe, while animation is being done by Sola Entertainment.

If you don’t know Sola Entertainment, they have previously worked on the 2D-styled Tower of God (for streaming company Crunchyroll), Bladerunner Black Out: 2022, plus 3D efforts Blade Runner: Black Lotus and Ghost in the Shell SAC: 2045.

On the works so far, Executive Producer Philippa Boyens says: “I’m in awe of the creative talent who have come together to bring this epic, heart-pounding story to life, from the mastery of Kenji Kamiyama to a truly stellar cast. I cannot wait to share this adventure with fans of cinema everywhere.”

Warner Bros. also revealed that animation work has been underway since last year at Sola Entertainment, and voice casting will be announced very soon.

It’s probably not well known, but Kamiyama did an interview late last year with Japanese media outlet Akiba-Souken where he touched on his work on The War of the Rohirrim briefly.

TORn has the following translation of relevant pieces from that article and Kamiyama’s comments:

What makes anime an anime?

Kamiyama is busy working on a number of projects, including directing the spin-off anime “The Lord of the Rings: The War of the Rohirrim” from the blockbuster movie “The Lord of the Rings.”

The soon-to-be-released “Star Wars: Visions – Ninth Jedi” is based on Kamiyama’s own ideas, he wanted to go back to the original story of a young man travelling the countryside, who gets involved in the battle over the Galactic Empire. Kamiyama was given the official Star Wars history lecture but also freedom to create his own story and setting within that realm.

Kamiyama is currently working on “The Lord of the Rings: The War of the Rohirrim.” He says that “First of all, the existence of the live-action version of the “Lord of the Rings” series created by J.R.R. Tolkien’s original work and director Peter Jackson is tremendous. For Hollywood, there is no national policy for the film industry, but it has become a core industry of the region.”

“I feel that the small scale of Japanese animation is good, and that it has a different dimension from ‘true’ (ie live action) movie production,” he says.

“However, working on “The Lord of the Rings: The War of the Rohirrim” has the difficulty and fun that makes me realize things like ‘probably Hollywood is making movies like this’.

“It’s completely different to working on other projects. Because we are focusing on making it as ‘entertainment’, it is possible to create works that guarantee a certain level of quality depending on the budget scale and staffing. There is a lot of discussion about the screenplay, the process is similar to building a stadium or a bridge. I think “The Lord of the Rings: The War of the Rohirrim” will create a new level of animation production.”
