Directed by Haruo Sotozaki, Infinity Castle follows on from Demon Slayer season 4. The movie is the first of an upcoming trilogy based on the Infinity Castle arc from the Demon Slayer: Kimetsu no Yaiba manga, and follows Tanjiro Kamado as he takes on an Upper Rank demon Akaza, in a bid to save the head of the Corps.

Crunchyroll has officially announced that fans in the United States will get the chance to see the Demon Slayer: Kimetsu no Yaiba Infinity Castle feature film in theaters a full three days early. The only catch is that hopeful audience-goers will have to be Crunchyroll Mega and Ultimate Fan subscribers in order to get their early screening tickets.

The Deadpool & Wolverine star has been cast as Keizo in the English dubbed version of Demon Slayer: Kimetsu no Yaiba Infinity Castle. However, many anime fans believe that the casting is not fair to other voice actors in the industry, and feel that Taum has only been cast because he is a big Hollywood name.
