Originally planned for late 2018, the feature film for Kabaneri of the Iron Fortress: The Battle of Unato has arrived with a May 10th, 2019 premiere in Japan.
The series was an interesting from a design perspective as it reunited some Attack on Titan colleagues with director Tetsuro Araki and writer Ichiro Okouchi.
We’ve known that for a bit but they’ve now updated their series page for it to include the first trailer for the film.
