Producers are Ed Zwick and Marshall Herskovitz under their Bedford Falls Company with Black Bicycle Entertainment’s Erika Olde, Rick Solomon and Potboiler’s Andrea Calderwood. Susan Kirr is executive producing. CAA is handling the domestic rights while IM Global is selling international rights.

The project was unveiled in February at Berlin with Chastain starring as Catherine Weldon, a portrait painter from 1890s Brooklyn, who travels to Dakota to paint a portrait of Sitting Bull, and becomes embroiled in the Lakota peoples’ struggle over the rights to their land. Weldon wrote letters to the federal government on behalf of Sitting Bull and lived on the land for several years with her son.
