Algues noires

In a dilapidated house by the ocean, a woman, worn down by time and solitude, lives a reclusive life. Every day, she performs the same unsettling ritual: extracting thick black algae from the pipes, cracks and invisible fissures, as if the house were rotting from the inside. Every afternoon, she drags this living matter to a cliff and throws it back into the sea.

Directed by Nathan Vaillant, Algues noires leans on a strong ensemble — Caroline Gay — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about screen titles of 2025.
