The anime series “Demon Slayer: Kimetsu no Yaiba” is currently dominating Japanese cinemas, marking the beginning of a complete trilogy of movies. However, production on these new films has been underway longer than many fans might have expected. When the TV adaptation of “Demon Slayer: Hashira Training Arc” concluded its four-season run, it was unexpectedly revealed that the franchise would expand with a full-length movie trilogy, adapting the Infinity Castle arc from Koyoharu Gotoge’s original “Demon Slayer” manga series. But this project has been in development for quite some time before the announcement was made.
The movie “Demon Slayer: Kimetsu no Yaiba Infinity Castle,” initially announced in Summer 2024, hit Japanese theaters only a year later. Although it may appear to be a rapid development, the truth is that this new trilogy has been under production for several years. As reported by @imhimgojou on X, the first film of the trilogy had actually been in production for three and a half years before its release.
Demon Slayer: Infinity Castle Has Been in the Works for a While
Based on the insider information disclosed to fans upon the launch of the latest movie, “Demon Slayer: Kimetsu no Yaiba Infinity Castle Chapter 1” was in production for a span of three and a half years. Following the unveiling of Mugen Train, the team opted to make Infinity Castle a trilogy for the big screen as well. This timeline for the first film, combined with the ongoing TV anime, clearly illustrates the massive scale that “Demon Slayer” has grown into for ufotable over time.
In the end, this decision turned out to be beneficial for the movie, as it’s surpassing milestones that Mugen Train had previously achieved and seems destined for significant box office success when all three films are released. Given the lengthy production process of the initial film, there’s speculation about when or if we’ll see the remaining two movies in the trilogy. The teams responsible for the TV series and feature films have a considerable task on their hands to deliver the final installments.
When Does Demon Slayer’s New Movie Come Out in the U.S.?
After debuting in Japan, “Demon Slayer: Kimetsu no Yaiba Infinity Castle Chapter 1” is quickly making its way to North America. Starting from September 12th, you’ll be able to catch it in theaters across the United States and Canada. The film will feature both Japanese and English audio options, and will also be available in premium and IMAX formats. International screenings for the movie are set to start this Summer, with release dates varying by territory.
The movie “Demon Slayer: Kimetsu no Yaiba Infinity Castle” clocks in at 2 hours and 35 minutes, making it longer than three “Avengers” films. This suggests a lot is crammed into the first film, with potential for even more in the sequels. As of now, there’s no announced release date or timeframe for these movies, hinting that fans might have to wait longer than they’d prefer for new installments.
