The Unknown at Cannes
Arthur Harari’s third feature, *The Unknown* (L’Inconnu), opened the 2026 Cannes competition. Co-written with brother Lucas Harari and screenwriter Vincent Poymiro, the film stars Léa Seydoux and Niels Schneider.
Creative Background
Harari, grandson of actor Clément Harari, won the Palme d’Or for *Anatomy of a Fall* (2023). *The Unknown* adapts his graphic novel *The Case of David Zimmerman*. Tom Harari handled cinematography; the score repeats a piano motif.
Plot Core
Photographer David (Schneider) attends a costume party, meets Eva (Seydoux), and after a brief, wordless sexual encounter an entity swaps their bodies. David awakens in Eva’s body; his original body later houses a missing 20-year-old woman, Malia (Lilith Grasmug). The pair pursue clues amid unexplained phenomena.
Production Timeline
The graphic novel was finished before 2025; filming wrapped early 2026. *The Unknown* premiered at Cannes in May 2026, runs 146 minutes, and earned a 3/5 rating from *The National*.
Reception Overview
Critics describe the film as “mesmeric” and “dreamlike” but note its length, opaque mechanics, and lack of resolution. Seydoux’s and Schneider’s performances receive praise.
Themes and Impact
The story foregrounds bodily autonomy, gender distress, and transformation. Reviewers connect it to anxieties about hyper-connectivity, identity erasure, and trans experiences, suggesting it may influence debates on gender representation.
Filmmakers’ Statement
Harari has said he avoids defining the film’s allegory, urging viewers to confront questions of metamorphosis, identity, and displacement without explicit guidance.
Critical Concerns
Some reviewers label the narrative “confusing” and “overly long.” Trans-rights observers warn that the gender-swap premise could reinforce harmful tropes.
Divergent Interpretations
Analyses differ: one reads the film as commentary on sexual trauma, another emphasizes gender identity, while a third proposes a simulation-theory angle. The fate of Eva and the nature of the swapping entity remain unexplained.

- “When I started filming, I remember the first scene I shot, I thought to myself, there you go, I am David.” — Léa Seydoux
- “At its most basic level, Arthur Harari’s “The Unknown” is a mesmeric, Antonioni-flavored modern thriller about a sentient STD of unknown origin (think: “It Follows”) that makes people swap bodies with their partners — more accurately thought of in this context as prey — during sexual intercourse.” is a mesmeric, Antonioni-flavored modern thriller about a sentient STD of unknown origin (think: ‘It Follows’) that makes people swap bodies with their partners.” — *IndieWire* review
