The Unknown, Arthur Harari's latest film, hits theaters on August 26, 2026. Presented in competition at the Festival de Cannes 2026, this 2h20 fantasy thriller stars Léa Seydoux and Niels Schneider.

David Zimmerman is approaching his forties and lives a reclusive life. A photographer with no notable career, he agrees to tag along with friends to a party where an unknown woman catches his eye. After following her, he wakes up a few hours later in her body.

The film is adapted from the graphic novel The Case of David Zimmerman, written by Arthur Harari alongside his brother Lucas Harari. The pair also co-writes the screenplay with Vincent Poymiro. The cast also features Valérie Dréville, Shanti Masud, Radu Jude, Jonathan Turnbull, Lilith Grasmug and Victoire Du Bois.

The Unknown marks Arthur Harari’s return behind the camera after Onoda: 10,000 Nights in the Jungle, which opened Cannes’ Un Certain Regard section in 2021. The filmmaker has since co-written with Justine Triet the screenplay for Anatomy of a Fall, the 2023 Palme d’Or winner and Best Original Screenplay Oscar recipient.
