According to Deadline, Brian Cox is set to perform the English voice role for Helm Hammerhand in Warner Bros. Animation’s upcoming anime feature, The Lord of the Rings: The War of the Rohirrim.

Helm Hammerhand is described as the protaganist of the tale, but the real surprise is the inclusion of Miranda Otto. Otto will reprise her Éowyn role from Peter Jackson’s The Lord of the Rings and serve as the film’s narrator.

In addition, Gaia Wise voices Hammerhand’s daughter, Hera. Luke Pasqualinoi will voice the Dunlending chieftain Wulf.

The story outline given to Deadline is as follows:

The anime feature, directed by Kenji Kamiyama, is set 183 years before the events chronicled in the original trilogy of films. 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, Hera, the daughter of Helm, must summon the will to lead the resistance against a deadly enemy intent on their total destruction.

Helm’s daughter is not named in Appendix A of The Lord of the Rings. However, the story describes how relations between Helm and Wulf’s father Freca sour dramatically after Freca attempts to use her as a political pawn. Her ultimate fate is one of the mysteries of the ensuing war.

Warner Bros. Animation has also released a new piece of concept art that appears to show Helm at the gate of his eponymous fortress. It’s reminiscent of this scene during the depths of the Long Winter:

One night men heard the horn blowing, but Helm did not return. In the morning there came a sun-gleam, the first for long days, and they saw a white figure standing still on the Dike, alone, for none of the Dunlendings dared come near. There stood Helm, dead as a stone, but his knees were unbent.

The voice ensemble also includes Lorraine Ashbourne (Netflix’s Bridgerton), Yazdan Qafouri (I Came By), Benjamin Wainwright (BBC One’s World on Fire), Laurence Ubong Williams (Gateway), Shaun Dooley (Netflix’s The Witcher), Michael Wildman (Fast and Furious Presents: Hobbs & Shaw), Jude Akuwudike (Beasts of No Nation), Bilal Hasna (BBC’s Sparks) and Janine Duvitski (ITV’s Benidorm).

The film will be released on April 12, 2024.
