Hollywood's hunt for the next anime franchise to bring into live action may have landed on a giant monster. According to scooper Daniel Richtman, Sony is developing a live-action adaptation of Kaiju No. 8, the manga and anime hit from creator Naoya Matsumoto.
The project has not been announced, and neither Sony nor Crunchyroll has commented on it. Richtman's report, which he first posted for subscribers earlier this month and repeated on social media this weekend, also leaves out the most basic detail: whether this is meant to be a theatrical movie or a series. No filmmakers or cast are attached either, so this should be treated strictly as a rumor until Sony says otherwise.
Why Kaiju No. 8 Makes Sense For Sony
On paper, this would be an easy property for Sony to pursue. The company owns Crunchyroll, which streams the anime around the world, and it already put the franchise in theaters with Kaiju No. 8: Mission Recon in 2025. That compilation film recapped the first season and added a brand new episode, Hoshina's Day Off, with Sony Pictures handling distribution in North America.
Sony has also been building infrastructure for exactly this kind of project. At Crunchyroll's Anime Future Forum in New York earlier this month, Sony Pictures Entertainment launched Crunchyroll Storyworks, a new division with a mandate that includes developing live-action versions of Japanese anime. Sony veteran Tohru Iokibe is running it, and the company says Japanese creators will be kept closely involved in each adaptation. No Storyworks projects have been named yet, so there is no official link to Kaiju No. 8, but the timing has fans connecting the dots.
Then there is the box office. Sony and Crunchyroll's Demon Slayer: Infinity Castle set a record for the biggest anime opening ever in the US last year and became the highest-grossing anime film of all time. Numbers like that make it easy to understand why studios are eager to invest more in anime properties.
The Story Behind The Monster
For moviegoers who have not read it yet, Kaiju No. 8 has a premise built for a blockbuster. Kafka Hibino is a man in his thirties who works on a crew cleaning up the remains of giant monsters after giving up on his dream of joining Japan's Defense Force. When he suddenly gains the power to turn into a kaiju himself, he has to hide what he has become while finally trying to earn his place on the front lines.
Matsumoto's manga ran on Shueisha's Shonen Jump+ from July 2020 to July 2025, finishing with 16 volumes and more than 20 million copies in circulation. The Production I.G anime, which brought in Studio Khara to supervise its kaiju designs, aired its first season in 2024 and its second in 2025. A conclusion arc adapting the end of the manga has been announced but not yet dated.
The Live-Action Challenge
Turning Kaiju No. 8 into live action would be a big visual effects job. The series lives on massive creature fights, and Kafka's transformation needs to look just as impressive as the monsters he battles. The good news is that kaiju have never been in better shape on the big screen. Toho's Godzilla Minus One won the Oscar for Best Visual Effects, proving that well-made monster movies can win over audiences and awards voters alike.
The tone is the other hurdle. Kaiju No. 8 mixes big action with workplace comedy and an underdog story about a guy who thinks his chance has passed him by. Getting that balance right will matter just as much as getting the monsters right.
Sony already has another anime adaptation in the works with its live-action One Punch Man, so a Kaiju No. 8 project would fit a clear pattern if it turns out to be real. For now, fans will have to wait for official word.
Do you want Sony to take Kaiju No. 8 to theaters as a big monster movie, or would you prefer the anime stay the definitive version?
