The film’s revisionism was nothing new--both Ralph Nelson and Arthur Penn had turned the tables on western clichés back in 1970 with Soldier Blue and Little Big Man, respectively--but Costner and screenwriter Michael Blake (who adapted his own 1987 novel) reinvigorate the argument with depth of character and a narrative scope that allows for various shades of gray across all perspectives.
Two decades earlier, A Man Called Horse and Little Big Man showed characters attempting to bridge the divide between white American culture and Native American tribalism, but Costner went for broke with his large-scale, Panavision epic, clocking in at three hours.
