Charlotte Le Bon, Pio Marmaï, Vincent Macaigne and Cécile de France are filming S’aimer sur Mars, Cédric Klapisch’s ensemble comedy slated for release in cinemas in 2027.

Cédric Klapisch is behind the camera on S’aimer sur Mars, a chorale-style comedy slated for a theatrical release in 2027. Charlotte Le Bon, Pio Marmaï, Vincent Macaigne, Cécile de France, Mariia Minieieva and Julien de Saint-Jean round out the cast announced by STUDIOCANAL, Ce qui me meut and France 2 Cinéma. Filming, which began on September 17, 2026, is taking place in Marseille through November 13.

Charlotte Le Bon portrays Jeanne, 36, a producer of a romantic series for an American streaming platform. She shares her life with Julien, played by Pio Marmaï, the show’s lead who longs to work in the theatre and in auteur cinema. At the release of season two, the couple faces professional and family tensions.

Jeanne must also work with the two screenwriters, Laurent and Justine, played by Vincent Macaigne and Cécile de France, a couple who refuse to be boxed in. Opposing them, the young stars Natalia and Jean, portrayed by Mariia Minieieva and Julien de Saint-Jean, love each other on screen but can’t stand each other on set. The film follows three couples at different ages, balancing their personal lives with the fiction they’re creating.

S’aimer sur Mars extends the collaboration between Cédric Klapisch and Pio Marmaï. The actor had already appeared in Ce qui nous lie, a family drama set on a Burgundian wine estate, and later in En corps, where his performance earned him a César nomination for Best Supporting Actor.
