The upcoming drama, "S'aimer sur Mars" (which translates to "Love Each Other on Mars"), marks a significant moment in Klapisch's filmography. While the acclaimed director has worked extensively with both Marmaï and de France individually, this film will see them share the screen under his direction for the first time. Pio Marmaï, who takes on the lead role, has previously collaborated with Klapisch on the critically well-received Ce qui nous lie and En corps, the latter earning him a César nomination for Best Supporting Actor.

Cécile de France, a familiar face in Klapisch's cinematic universe, is set for her fifth collaboration with the director. She first gained widespread recognition through Klapisch's beloved "Spanish Apartment" trilogy, appearing in L’Auberge espagnole, Les Poupées russes, and Casse-tête chinois. More recently, she starred in his 2025 film La Venue de l'avenir, which also featured Vincent Macaigne, another actor set to join the cast of "S'aimer sur Mars." The ensemble for the new film is further bolstered by the talents of Charlotte Le Bon and Julien de Saint-Jean.

Details surrounding the plot of "S'aimer sur Mars" are being kept tightly under wraps by Klapisch, who previously won a César for Best Screenplay in 1997 for Un air de famille. Production has just commenced in Marseille and is expected to continue for approximately one month. As of now, no official release date has been announced for the film.

Both lead actors have busy schedules ahead. Pio Marmaï is slated to appear in François Ozon's Le Mal est fait, set for release on February 10, 2027. Cécile de France, meanwhile, will be seen alongside Charlotte Gainsbourg in L'affaire Marie-Claire, which is expected to hit screens on November 4. With "S'aimer sur Mars," Klapisch continues his tradition of crafting engaging human stories, now with the added intrigue of this fresh and highly anticipated on-screen pairing.
