The film, to be shot in the Himalayas, has been co-produced by Julie Gayet's Rouge International and Elisa Soussan's myFamily.
Kev Adams, best known for films like "Les Profs 2" and "Les Nouvelles Aventures d'Aladin", will play the lead in the film.
"nOmber One" tells the story of riders, the daring last action heroes who risk their lives for a beautiful run, for an ephemeral race carved out on the sheer, white face of a remote and isolated mountain.
The movie has been written by Hazanavicius, who is the brother of "The Artist" helmer Michel Hazanavicius, along with Stephane Dan, Mary-Noelle Dana, and Alexis Galmot.
