Léa Seydoux and Joel Kinnaman are set to topline the film adaptation of Rupert Isaacson’s New York Times bestseller, The Horse Boy. Israeli filmmaker, Ari Folman, is set to direct. The film is scheduled to start filming in October in the U.K., Mongolia, and in Joel’s home country, Sweden!

VARIETY – The film follows the journey of Emily and Jonathan’s son, Noah, an autistic child who rarely talks and isn’t improving despite his parents’ efforts to connect with him. When Jonathan notices that Noah is more peaceful and seems more able to communicate while riding horses, he sets off to take his family for a ride through the Mongolian plains to meet shamans in order to cure his son.

“‘Horse Boy’ is a passion project for Folman, who said he felt compelled to explore this important story in a cinematic way. “‘Horse Boy’ is a love story about a man and a woman who, against all odds are willing to take the biggest possible risk, not only to rescue their son, but to rescue their love for each other, their memories of the bond they used to share,” said Folman, who added that Mongolia will be portrayed in a unique way in the film.
