Buffalo Bill and the Indians, or Sitting Bull's History Lesson (1976)

Buffalo Bill and the Indians, or Sitting Bull's History Lesson is a 1976 revisionist Western film directed by Robert Altman and based on the 1968 play Indians by Arthur Kopit. It stars Paul Newman as William F. Cody, alias Buffalo Bill, along with Geraldine Chaplin, Will Sampson, Joel Grey, Harvey Keitel, and Burt Lancaster as Bill's biographer, Ned Buntline. It was filmed in Panavision by cinematographer Paul Lohmann.

As in his earlier film M*A*S*H, Altman skewers an American historical myth of heroism, in this case the notion that noble white men fighting bloodthirsty savages won the West. However, the film was poorly received at the time of its release, as the country was celebrating its bicentennial.
