Cannes 2026: Hirokazu Koreeda’s ‘Sheep in the Box’ Challenges AI Narratives

The 2026 Cannes Film Festival has served as a significant stage for Japanese cinema, with the country honored as the Marché du Film’s Country of Honor. Among the featured works, Hirokazu Koreeda’s latest project, Sheep in the Box, has sparked intense discussion. Departing from the traditional expectations of science fiction, the film offers a meditative, if unsettling, look at grief, technology and the complexities of parenthood.

A Departure from Dystopia

While many attendees arrived at the premiere anticipating a high-tech, dystopian thriller, Koreeda’s film takes a quieter, more domestic approach. The story follows a middle-class couple in Kamakura, architect Otone Komoto and woodworker Kensuke Komoto, who adopt a humanoid AI replica of their late son. Rather than focusing on a “controlled-by-robots” narrative, the film examines the emotional fallout of attempting to replace a lost child with a synthetic counterpart.

Koreeda noted that audience reactions have been mixed, largely because viewers often expect a genre-typical cautionary tale. Instead, the director uses the AI humanoid, Kakeru, to explore the boundaries of human connection. The film highlights the artificiality of the situation through Kakeru’s programmed nature—specifically his awareness that he is not designed to feel sadness—which creates a profound sense of discomfort for the characters around him.

Research and Philosophical Depth

The film’s nuanced exploration of family dynamics is rooted in extensive research. Koreeda sought input from friends and acquaintances to understand the complexities of parent-child relationships, particularly the lingering trauma of abandonment. This research informed the strained connection between Otone and her own mother, a cycle that she inadvertently replicates with the AI child.

The title, Sheep in the Box, pays homage to Antoine de Saint-Exupéry’s The Little Prince. Koreeda uses this thematic framework to ground the film’s more abstract concepts of identity and memory. When asked about the absence of certain archetypal figures from the book, such as the rose, the director emphasized his focus on the boy who interacts with Kakeru’s GPS as a key philosophical anchor for the protagonist.

The Future of Japanese Cinema at Cannes

Koreeda reflected on the broader state of the Japanese film industry during his time at the festival. He expressed optimism regarding the increased representation of Japanese directors on the global stage, noting that peers like Ryusuke Hamaguchi and Koji Fukada have found significant support in France. However, he also highlighted a critical need for the Japanese film industry to better cultivate and support emerging domestic talent.

Key Takeaways from the 2026 Cannes Premiere

• Thematic Focus: The film explores the ethics of reanimation and the psychological impact of using AI to process grief.
• Performances: Child actor Rimu Kuwaki portrays Kakeru, with direction that focuses on the discomfort his presence causes the adults rather than a robotic physical performance.
• Global Outlook: Koreeda advocates for stronger domestic support structures for Japanese filmmakers to ensure continued international success.

As Sheep in the Box moves toward its eventual release by Neon, it stands as a testament to Koreeda’s willingness to experiment with genre while maintaining his hallmark sensitivity. Whether audiences embrace this pivot or continue to grapple with its unconventional rhythm, the film remains a central point of conversation in this year’s festival lineup.
