Wielding the biggest movie production-distribution-sales muscle of any film company outside the U.S., Euro film-TV group Studiocanal has boarded Marion Cotillard starrer “From the Land of the Moon” (Mal de Pierres), an upscale period drama produced by Alain Attal’s Les Productions du Tresor.

Studiocanal will handle world sales rights to “From the Land of the Moon” and distribute it France, the U.K., Germany, Australia and New Zealand, where it runs direct distribution operations.

Cotillard will play opposite Louis Garrel, a French actor who earned a Cesar nom for his perf in Bertrand Bonello’s “Saint Laurent” and made his directorial debut with “Two Friends,” which opens at Cannes’ Critics Week this year.

Witten by Garcia and Jacques Fieschi (“Yves Saint Laurent”) and adapted from Milena Agus’ bestseller “Mal de pierres,” the post-World War II drama is a portrait of a sensitive and wild-spirited woman torn between the constraints of conventional society and her urge to find true love.

The key crew comprises cinematographer Christophe Beaucarne and costume designer Catherine Leterrier, who both worked on Anne Fontaine’s “Coco Before Chanel,” as well as production designer Arnaud De Moleron (“Augustine”).

Studiocanal and Les Production du Tresor collaborated for the first time on Maiwenn’s “Mon Roi,” which plays in competition.  Studiocanal is also in Cannes with “Macbeth,” starring Cotillard and Michael Fassbender.

Les Productions du Tresor is developing Douglas’ Attal’s “How I Became a Superhero,” France’s first big-scale superhero movie, and Stephanie Di Giusto’s “The Dancer” with Soko playing famed terpsichorean Marie-Louise Fuller. Elle Fanning is in negotiations to also star in the film, which is sold by Wild Bunch.

Producing Guillaume Canet’s “Tell No One,” “Little White Lies” and “Blood Ties,” Radu Mihaileanu’s “The Concert” and Maiwenn’s “Polisse” and now “Mon Roi,” Les Productions du Tresor is one of France’s most consistent suppliers of high-profile movies which can go boffo in France and sometimes break out to significant box office abroad.
