Léa Seydoux to Star in ‘Anatomy of a Fall’ Co-Writer Arthur Harari’s Next Film ‘The Unknown’ From Pathe (EXCLUSIVE)

Pathe has boarded “The Unknown,” the highly anticipated next movie from “Anatomy of a Fall” co-writer Arthur Harari, starring Léa Seydoux. “Anatomy of a Fall,” which Harari co-wrote with director Justine Triet, won an Oscar, two Golden Globes, a BAFTA and the Palme d’Or at last year’s Cannes Film Festival.

Rolling off “Dune: Part Two,” Seydoux is set to headline the fantasy movie. The actor, whose career spans Hollywood and European productions, recently starred in Bertrand Bonello’s sci-fi romance “The Beast.”

“The Unknown” is produced by Paris-based Bathysphere and is scheduled for completion in the first half of 2026. Pathé is co-producing, and will introduce the package to buyers at the Cannes Market. The banner will also distribute the movie in France.

While the plot remains under wraps, Harari teased that the project is “a mix of realistic urban chronicle, fantasy film, investigation, melodrama and daydream.”

“[It] will continually metamorphose before our eyes, while its horizon will be the character’s profound and irreversible transformation,” Harari continued.

“The Unknown” marks the third directorial outing by Harari and his most ambitious to date. His previous movie, “Onoda: 10,000 Nights in the Jungle,” opened 2021’s Un Certain Regard at Cannes and went on to win several awards including the César Award for best original screenplay.

Nicolas Anthomé, who produced the movie at Bathysphere, said “The Unknown” will “be a realistic fantasy film, with the fantasy understood, first and foremost, to be a spectacular promise of vertigo, evocation and poetry.” Pathé will handle international sales and release the film in France and Switzerland.
