Sony Is Reportedly Developing a Live-Action ‘Kaiju No. 8’ Adaptation, but Plenty Remains Unknown

Hollywood’s appetite for anime and manga adaptations shows no sign of slowing down. Studios have spent the past few years chasing franchises with built-in fan bases, and Japanese properties keep landing at the top of the wish list. One of the biggest recent hits in that space may now be heading to live action.

Sony is reportedly developing a live-action adaptation of ‘Kaiju No. 8‘, according to a report from an industry scooper. The report doesn’t say whether the project is a movie or a series, and no writers, directors or producers have been named. Sony hasn’t confirmed anything, so for now this belongs in the rumor category.

Still, the news makes sense when you look at Sony’s position. The studio’s Crunchyroll arm streams the anime, and Sony Pictures has already handled theatrical releases for the franchise. A live-action version would keep the property in the family even as the anime approaches its conclusion.

The story was created by Naoya Matsumoto and began on July 3, 2020, on Shueisha’s Shonen Jump+ platform. It follows Kafka Hibino, a 32-year-old stuck cleaning up monster remains for a living, who gains the power to turn into a kaiju himself. He then joins Japan’s anti-kaiju Defense Force, all while hiding his secret and chasing a promise he made to a childhood friend.

The manga ended with Chapter 129 on July 18, 2025, after a run of just over 5 years. It has more than 18 million copies in circulation, with Viz Media publishing it in English. Matsumoto has said he drew on his own frustrations as a 30-year-old who hadn’t reached his dream, and that ‘Shin Godzilla’ was a major inspiration.

The anime adaptation, produced by Production I.G with kaiju design supervision from Studio Khara, premiered in April 2024. Its first season ran through the summer, and a second season followed on July 19, 2025. Season 3, billed as the Final Chapter, was announced at Jump Festa and will adapt the manga’s ending, though it doesn’t have a premiere date yet.

Sony has also put the franchise on the big screen before. In April 2025, Crunchyroll and Sony Pictures released ‘Kaiju No. 8: Mission Recon’, a compilation film that recaps the first season and adds a new episode titled ‘Hoshina’s Day Off’. It was an early sign that the studio sees theatrical value in the property.

The timing also reflects Sony’s recent success with anime in theaters. Its ‘Demon Slayer: Infinity Castle’ opened to $70 million domestically in September 2025, which was the biggest anime opening ever, and went on to become the highest-grossing anime film of all time. That result has likely made executives more confident about adapting Japanese properties.

Live-action anime adaptations are also becoming a trend across studios. Lionsgate’s live-action ‘Naruto’ movie is reportedly set to begin filming in early 2027. If the ‘Kaiju No. 8’ report is accurate, Sony would be joining a growing field.

A live-action ‘Kaiju No. 8’ would face obvious hurdles. The story depends on massive creature designs and big action sequences, which means heavy CGI requirements. Poor visual effects could undermine the whole project, and casting would need to balance fan expectations with global appeal.

There is also the question of format. The manga’s episodic structure might need to be condensed or rearranged for a film or reorganized for a series. Fans have already floated names for directors, with some suggesting Guillermo del Toro because of his love of kaiju and anime, though that is pure speculation.

For now, there are no official details. A formal announcement from Sony or Crunchyroll would clarify whether this is a movie, a series or something else. Since the report says the project is in development, it could be a long time before cameras roll.

That uncertainty is typical for early-stage Hollywood projects, which can change quickly or stall entirely. But the underlying logic is strong: a hit manga, a popular anime and a studio that already owns the distribution pipeline. If anything, the surprise is that it took this long.
