Demon Slayer: Kimetsu no Yaiba Infinity Castle’s Cast on Why Finishing on the Big Screen Is the Best Move

 “It’s Larger Than Life, and ‘Demon Slayer’ Deserves No Less.

  • TopMob: “The series has chosen to wrap up the story with three movies on the big screen. Why do you feel like moving to films is the best way to wrap the story up?”

As a classic TV enthusiast, I must admit, I was initially skeptical about this movie business replacing my beloved series. When I first heard about the idea of ending ‘Mugen Train’ as a film, I couldn’t help but think it was an unusual choice. However, after witnessing the cinematic spectacle that was ‘Mugen Train’ in theaters, I found myself yearning for more – the collective energy of the audience, the thrill of watching on a grand scale, the increased budget allowing for enhanced visuals, and the luxury of not having to wait weekly but just once a year. Sometimes, experiences can change your perspective, and I believe this is an excellent conclusion to the [series].

Adam McArthur: I believe when you witness the fight sequences and animation, and they are as grand as they appear on a small screen, they will only become even more impressive on a large screen. In other words, every aspect, including sound design and visuals, will really stand out on the big screen.

Abby Trott muses that she’s unsure of the most fitting conclusion for a series like this given its grand scale. However, it seems they might have contemplated ending it in a truly impressive fashion – by splitting it across three IMAX films.

As a cinephile, I find it truly exhilarating to step into the grandeur of a movie theater. The big screen experience is distinct, and I’ve experienced this firsthand at the last premiere where they played the final two episodes of a series. Streaming those episodes didn’t move me to tears, but watching them in the theater did. The atmosphere, the collective emotions of the audience, and the sheer beauty of it all make a theater screening an unparalleled experience. If you have the opportunity, do catch it on the big screen!

Zeno Robinson: Anime films frequently tell a thorough, high-intensity story from start to finish, with top-notch animation and production quality. Since ending such a globally popular franchise like this one should be exceptional and reach a wide audience, they are putting in extra effort to make each movie outstanding enough to be viewed in formats like IMAX. In other words, they’re sparing no expense to ensure that every film is the best it can possibly be. They’re working on sections of the film rather than producing the entire season at once.

As a devoted movie enthusiast, I can confidently say that the climactic battles in this series are nothing short of breathtaking. The choreography is so intricate and visually stunning, it’s hard to put into words. So, if you want to truly immerse yourself in the spectacle, there’s no better place than a grand theater like this one. It’s a visual and auditory feast that I’m absolutely thrilled they chose to showcase on such a scale.

Johnny Yong Bosch: Given the massive scale of things, the animation is so intense that it seems justified to invest a substantial amount of money to make it visually stunning. This way, they could splurge all at once. In reality, it’s broken down into three parts, but with so much detail, I believe this approach makes sense. You can truly appreciate it on the big screen.

Brianna Knickerbocker states that due to its grandeur, “Demon Slayer” merits an equally spectacular conclusion. She describes the narrative as both extensive and potent, implying it warrants a fitting finale.

Brook Chalmers: Don’t you agree that this event is quite grand and deserves to be viewed on a large screen? Additionally, when we usually watch anime, it’s often solitary at home. But this occasion offers us the unique chance to share the experience with many others in one location. And that’s truly significant.

As a devoted cinema enthusiast, let me tell you, there’s nothing quite like witnessing anime on the grand screen! Remember the exhilarating experience we had with ‘Mugen Train’? The collective emotion in the theater was palpable, from heartrending sobs during poignant moments to roaring laughter at comedic scenes – I could literally feel everyone’s reactions! It was an unparalleled immersion into the series, making me part of something greater. So, you can bet your bottom dollar that I eagerly anticipate experiencing this cinematic magic once again!

Jonah Scott expressed that the artist, when crafting a story, has the freedom to mold it according to their vision for the world. While manga is becoming more mainstream, there’s still an obstacle in attracting interest, much like comic books. The challenge lies in breaking through this barrier and ensuring people actually read the manga. This approach allows them to entice readers by making adjustments such as omitting certain elements or adding additional lines to enhance the story’s realism.

It seems like you’re trying to express that incorporating memorable fan moments could make anime more mainstream and popular, as production costs are high.

I believe these impactful fan moments are what could potentially drive anime into the mainstream. I think more shows should adopt this approach because the production of anime can be expensive. Why not invest in making it exceptional then? If you’re going to spend a lot, why not go all out and make it extraordinary?
