Killers of the Flower Moon: Martin Scorsese’s real-life crime epic showcases the distinction between a film that is objectively long (it, after all, clocks at approximately 200 minutes when the end credits start rolling) and one that is subjectively long. Somber, never trying to be purely “entertaining”, the film nevertheless is always enthralling, as it tells the story of the preposterously bad treatment and systematic elimination of Osage people, who own oil rights in Oklahoma. Robert De Niro plays the big rancher of the place in a quietly threatening, very effective performance. Leonardo DiCaprio plays his nephew, not the sharpest tool in the shed but still instrumental in the process. As the young Osage woman who finds herself at the center of the killings, Lily Gladstone plays the character with quiet dignity in a beautifully layered performance. The superb pacing is in big part a result of editor Thelma Schoonmaker’s classy, efficient work. Cinematographer Rodrigo Prieto captures the action with a likewise elegant camerawork. Composer Robbie Robertson’s subdued score is a very good fit. This is top-shelf filmmaking all around, even if the dark subject makes the film a bit hard to watch.
