All You Need Is Killing may sound like a punch-you-in-the-face-titled new anime film brought to the US by GKids to the average moviegoer, but to those in the know, the movie is actually the latest in a long line of adaptations of its source material.

Undeniably, the most popular adaptation here is the cult-classic of Tom Cruise and Emily Blunt sci-fi movie Live Die Repeatalso known as Edge of Tomorrow. However, its roots go further than the Hollywood flick. Original 2003 novel by Hiroshi Sakurazakait was adapted into a manga by Ryosuke Takeuchi and described by Death Note ARTISTS Takeshi Obata. In essence, the new adaptation’s trajectory in anime a bit backward, at least through the traditional anime industry standards.

It follows Keiji, a soldier on foot in Earth’s effort to push back an alien species, with our only means, surprisingly, being mech suits to kill the invading hordes. Upon his untimely death, Keiji learns that he is trapped in a time loop that repeats the sun, with his only way out depending on finding a way to escape. But he was not alone. He is accompanied by humanity’s toughest soldier, Rita, who, tied to a death loop that resets each of them when they die, fights (with a giant cyber axe) with Keiji to get out of their purgatory and win the war once and for all.

As with any work with the proverbial “adaptation” attached, its diehard fandom is cautiously optimistic while having doubts about seeing their child come to life again through Studio 4°C (Sea Children). However, while the fan’s doubts were not lost on Studio 4°C’s Kenichiro Akimotothe director sat down with io9 to discuss why he felt compelled to stake his directorial debut on breathing new life into the acclaimed series.

However All You Need Is Killing which is Akimoto’s first time in the director’s chair—his resume includes serving as CG artist for Berserk: The Golden Age Arc trilogy and as a CGI director for Netflix’s Children of the Sea– to him, take to All You Need Is Killing boiled down to fate and “good” timing.

“I have talked to our president, (Eiko) Tanakaabout the possible management of a project. And at the same time, Warner Bros. put forward a proposal for a All You Need Is Killing animation project,” said Akimoto. “It happened with everyone working together as the perfect time.”

Time-loop stories are often about trauma, memory, and identity—and, in a case of art imitating life, All You Need Is KillingThe fandom feels its own version of that cycle, divided between purists and those who have resigned the series to life as a story so popular that it has been adapted several times. So while Studio 4°C’s stab at reimagining All You Need Is Killing certainly a newcomer to the many thronging the cinemas, it faces an uphill battle with its diehards, whose community remains famously divided between pessimists and cautiously optimistic fans who await how the story will change.

After all, even in Akimoto’s own estimation, the quality of the original novel was “very complete and perfect,” while the Hollywood live-action film, for taking its concept in a different direction, was “very entertaining.” By far the most obvious change in Akimoto’s adaptation of the story is that it follows Rita instead of Keiji, a first for the series, and adds more texture to the warrior by shaping his backstory beyond the tough exterior Keiji and fans of other adaptations know. For Akimoto, this change helped Studio 4°C create something new All You Need Is Killing adaptation worthy of standing alongside earlier adaptations.

“When I was put in charge of the animation, I wanted to approach it as a challenge to have our own originality in the project itself. And I know as a fan, I would have felt the same way, like, ‘Wait, please don’t change this.’ But at the same time, I also wanted to do something different. So this is the approach we take. “

Given that the Studio 4°C movie is All You Need Is To DieThe third adaptation, Akimoto understood, would invite comparisons. However, his hope is that the movie will not only be more true to the name of the title, the theme and the 3DCG action, but also capture the beauty of his dystopian sci-fi world in a way that only animation can.

“I wanted to show something beautiful within the story,” he said, especially noting how important Keiji and Rita are to each other despite the disastrous circumstances of their first meeting. “Even though the story and the concept are the same, I want everyone to experience a different form of entertainment.”

One way the film is really different All You Need Is KillingOther adaptations are his provocative, psychedelic art style. Compared to the dark, gritty look of manga and the template-leaning sci-fi Hollywood look of the 2010s (see Elysium and District 9), Studio 4°C’s aesthetic seems like a surprising, moving contradiction—one where the character models and background art are pastel, precise, and clean, but also guilty and intriguingly scribbly. It’s like if the elastic but kinetic action of ’90s anime Crayon Shin-chan is placed smack dab in the middle of a 2D-meets-3DCG sci-fi action thriller. A sentence that is difficult for anime fans to know.

About All You Need Is KillingAkimoto’s unique appearance impressed the character designer Izumi Murakami for slow-cooking the unique aesthetic of the anime film. In addition to serving as Akimoto’s directorial debut, the film also marks Murakami’s first time as a character designer. Although Akimoto admitted to giving him some rough ideas of how he envisioned Rita to look in the early stages of the film’s development, the visual palette All You Need Is To Die What audiences will see in theaters is a far cry from the initial suggestions he floated. Which, in Akimoto’s estimation, is for the better.

“Murakami took a lot of inspiration from the characters in the movie, and he drew a lot of different concept art for us. At first, the character design for Rita was very photorealistic,” he said. “But as he brushed it, it seemed to start to become more and more flat. That’s what I really liked about the design. As Murakami worked on his own sketches, he began to take Rita’s concept of HIM mind. That’s why his character design came to life.”

From there, Akimoto said he didn’t have to submit many requests or changes to Murakami once his unique, stylish identity as Rita flowed into the rest of the All You Need Is Killing. A visual tone, he says, is paramount to meshing with Studio 4°C’s penchant for glamorous 3D animation—a hard-to-find rarity in an industry where CG is often a whipping boy, dismissed as something anime fans can’t really relate to. outside some rare-case studio.

“The flatness of the character design is very important in my film, because these flat characters will be thrown into this 3DCG animation background. If the characters are too realistic, then the difference will be too sudden. So I wanted to challenge myself to create this flat type of animation style, and that’s how it was done.”

All You Need Is To Die will hit theaters on January 16.
