“Liking anime is actually cool, it just took the rest of the world a minute to catch on”: Zach Aguilar on Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle

A direct continuation of the anime’s fourth season, Demon Slayer: Kimetsu no Yaiba – The Movie: Infinity Castle is the first film of the planned theatrical trilogy that marks the beginning of the end for the familiar series. It’s an adaptation of the Infinity Castle arc of the manga by Koyoharu Gotouge. In the film, Tanjiro and the rest of the Demon Slayer Corps traverse through Muzan Kibutsuji’s Infinity Castle hideout, facing off against various enemies. Lives are lost, and sacrifices are made as Tanjiro gets closer to his decisive battle against the first demon. The film has earned over $730M (and counting) at the box office, beating out superhero blockbusters like Fantastic 4: First Steps and Superman. It also broke records, becoming the highest-grossing Japanese film of all time. Infinity Castle’s success marks the growing popularity of anime in mainstream media.

The Upcoming caught up with Zach Aguilar, the English voice actor for Tanjiro. Aguilar is known in the anime sphere for his work as Genos in One Punch Man, Slaine Troyard in Aldnoah. Zero and as Riku in the sequel series to the fan favourite anime Inuyasha, Yashahime: Princess Half-Demon. Aguilar spoke to us about the importance of adapting the climactic Infinity Castle arc as a film and the pressure of creating that cinematic experience for longtime fans of the anime. He expressed great love for the character of Tanjiro and detailed the techniques he learned in terms of preserving his voice when dubbing a character with plenty of nuanced emotions. The actor also spoke about the life lessons he learned in his journey with Demon Slayer. Aguilar commented on the growing popularity of anime and the importance of recognising it as an art form. Finally, he finished off our conversation with praises for Channing Tatum, who took on the role of Keizo in the English dub, for his performance.
