Léa Seydoux Carries Marie Kreutzer's 'Gentle Monster' to Bruising Effect

Léa Seydoux plays a concert pianist rebuilding her life in the Austrian hills in Gentle Monster, the new psychological drama from Corsage director Marie Kreutzer, which premiered at the 2026 Cannes Film Festival. The film arrives in theaters on October 30 and on Netflix on November 18.

The opening scene sets the method. Lucy, played by Seydoux, covers the Eurythmics' "Would I Lie to You?" at her piano, the lyrics carried away by the notes before they settle. A growl hides in Seydoux's silky voice. The Lucy we meet is still adapting to quiet countryside life after a career touring European capitals. When her husband Philip, played by Laurence Rupp, rushes in mid-song with a full panic attack, her patient consoling signals it is not the first time she has stopped to make room for him.

Kreutzer's script reveals little directly. The couple — with their young son Johnny, played by Malo Blanchet — unpack a big house with an even bigger garden somewhere in the Austrian hills. Fleeting references blame Philip's burnout for the move, yet he joyfully documents the new chapter with a Super-8 camera. Scenes of domestic bliss flicker on the reels as the only testament to his filmmaking career, except for a poster of Bergman's Persona propped against a wall. Kreutzer refuses to characterize Philip or his work in depth, while giving glimpses of Lucy's career as an avant-garde concert pianist who covers songs solely by male artists.

Whose story is it anyway?

The perspective is female in that the audience has more access to Lucy's psychology. But in the second act, Kreutzer splits it, introducing police officer Elsa Kühn, played by Jella Haase, who delivered a search warrant at the narrative's start. Off the clock, Elsa is a hyperindependent woman with an ageing, ailing father who tends to be inappropriate with the live-in nurse. Haase plays her as stoic as any lead in a police procedural.

Judith Kaufmann, cinematographer of The Teacher's Lounge and Corsage, lenses the film in crisp, exposing static wide shots, countered by an intimate soundtrack from French artist Camille.

What does the film draw from?

Gentle Monster marks Kreutzer's return to the psychological drama territory of 2019's The Ground Beneath My Feet, but it would not exist without the genre-bending Corsage. A turn of events following the completion of that her-story period film became the real-life basis for the new script. Readers familiar with a certain scandal that shook the Austrian film industry in 2023 will not be surprised by the plot twist that arrives early. The title refers to Philip's character.

Rupp, known primarily for TV roles and 2024's absurdist comedy Veni Vidi Vici, carries the load as a tortured man whose desperation and resentment are cloaked in love. His face remains expressionless as the relationship with Lucy strains and snaps; no amount of sorries can wash off the stench of secrets he exudes in every scene.

Seydoux, by contrast, almost carries the film's emotional weight like a crown. Her confidence as Lucy reads not as self-congratulation but as a genuine belief that things may not be so bad after all. Both Seydoux and Haase embody a relatable pretense — sparing the men who hurt them while simmering with rage inside.

For all its measuredness, Gentle Monster is a merciless film, aimed less at viewers than at its titular character. Some may deem the gesture exaggerated, yet a tenderness steers Kreutzer's script away from revenge, humiliation, or brutal punishment. For its taboo subject matter, that restraint already says a lot — and positions the film as one of the more quietly unsettling entries in this year's Cannes lineup heading into its autumn release.
