Jessica Chastain stars in a new western titled **Woman Walks Ahead**.
Chastain plays Catherine Weldon, a 1800s portrait painter from Brooklyn who befriends Sitting Bull.
Director Susanna White says she wanted to bring a female perspective to the world of westerns.
"It was a man's world, a very violent world, and where women were very marginalized characters ? as were the Native Americans in the stories. So what I fell in love within a few pages was the Native American characters were very layered, sophisticated, we were seeing that culture from a different point of view and discovering it through the eyes and ears of this extraordinary woman." Susanna White
"The most moving thing for me was I went and showed the movie at Rapid City a week ago and to show it to that Lakota community, they were so moved to be given the validation of their community being taken seriously." Susanna White
