Neon Releases U.S. Teaser for Arthur Harari’s The Unknown

Léa Seydoux’s widely praised lead turn in the teaser signals Neon’s planned 2026 U.S. release.

Overview

  • Neon released the official U.S. teaser on Friday, Sept. 4, 2026, and confirmed the film is slated for U.S. theaters in 2026 with a specific date to be announced.
  • The teaser presents the film’s premise: David, a Parisian photographer, wakes up in a young woman’s body after a drug-fueled party, a plotline taken from Arthur Harari’s screenplay co-written with Lucas Harari and Vincent Poymiro.
  • Coverage and the trailer foreground Léa Seydoux as Eva and Niels Schneider as David, and many outlets single out Seydoux’s performance as the film’s anchor.
  • Critical reaction from the Cannes premiere in May was mixed, with some reviewers praising the acting and atmosphere and others faulting the film’s handling of its body-swap themes, especially the framing of sexual transmission described in coverage as ‘the disease’ and an emphatic sex scene that divided critics.
  • The film carries the auteur pedigree of Harari, an Oscar-winning co-writer of Anatomy of a Fall, and features an ensemble cast and producers Nicolas Anthomé and Lionel Guedj, making the trailer release the next step in Neon’s festival-to-theaters rollout and a moment to watch for how audiences and critics respond ahead of its U.S. opening.
