Osage Nation Chief Geoffrey Standing Bear prepares to don a tuxedo, bow tie, and traditional blanket for the London premiere of Killers of the Flower Moon. This is the fifth time he has seen the three-and-a-half hour movie. "You have to watch it multiple times to get the depth." However, at the second Cannes Film Festival, he could not get much attention. “It was hard to concentrate on the movie because I was always watching celebrities,” he says with a laugh. Who are you like? “I saw Cate Blanchett, who played Galadriel [in The Lord of the Rings films], and she was right there. I just walked up to her and said, 'Hey, give me the gift of an elf. I wanted to say, ``Do you have one?'' but I thought it would be better to remain silent because it would embarrass people. But you know, I'm sitting next to Robert De Niro - that's pretty famous.

Chief Standing Bear is a gentle, healthy-looking 70-year-old man who seems to be enjoying his foray into show business, but few people could understand this. When Hollywood came knocking, he was suspected more strongly than the Osage Nation. In the broadest sense, American movies and television are not known for their sensitive portrayals of Native Americans. Native Americans, already suffering from the apocalyptic invasion of European settlers, spent much of the last century remaking their own history for entertainment and always as villains.

Additionally, the Osage have a special historical reason to distrust outsiders, as they are the victims of one of the worst American crimes of the 20th century, perpetrated by greedy whites. This story, now known as "The Reign of Terror," is so brazenly evil that it is almost impossible to understand. It is a combination of institutional fraud, economic exploitation, reckless racism, and calculated mass murder.
