Martin Scorsese Instagram – Killers of the Flower Moon was a movie that I had to make, a story that I had to tell. The Osage Reign of Terror is a true American tragedy, and the fact that the story was not widely known before the publication of David Grann’s book only deepened the feelings of betrayal, neglect and distrust in the Osage community. I would never have even considered making this picture without the cooperation and trust of the Osage community. They welcomed us in Oklahoma, and we began a remarkable collaboration that has never ended. I wanted to make a picture that belonged to all of us, working together. I hope that I succeeded.
