How do you gauge someone’s will to live? I once knew a film producer who said the two rules of moviemaking were, Never make a western and Never make a film in the snow. Well thank goodness nobody told screenwriter Taylor Sheridan who makes his directing debut here following the screenplays for the extraordinary Sicario and Hell or High Water, two of the best films in the past decade. Cory Lambert (Jeremy Renner) is an agent (read: animal catcher) for the US Fish and Wildlife Service working in the vast titular Native American reservation in Wyoming when he happens upon the body of a young woman Natalie Hanson (Kelsey Chow) who was his own late daughter’s best friend. He’s seconded by a neophyte FBI officer Jane Banner (Elizabeth Olsen) to help her as she has no expertise in tracking or this mountainous terrain the size of Rhode Island with just 6 police officers led by Graham Greene. While Cory is still dealing with the fallout of a divorce, having to forego caring for his young son when his ex is out of town for a couple of days in order to look for the killers, we unspool through family photos and start to understand some of his motivation for helping this officer who doesn’t even have the right clothing for minus 20: Cory’s mother in law loans her her late granddaughter’s clothing with the warning, These are not a gift. His young son is startled at the sight of this white girl in his dead sister’s clothes. Together Cory and Jane embark on a hunt when the coroner finds the girl has been likely multiply raped but drowned in her own blood because the alveoli in her lungs filled with freezing air as she ran barefoot from her assailants. She ran six miles. So it can’t officially be listed as murder. Then Cory finds a second body … With all Sheridan’s films now we see a certain pattern: the idea of borders, which also extend to different races and traditions and values transmuted through marriage, and of course singular acts of transgression which here comprise murder but obviously incorporate other acts of violation arising from untrammelled self-justification. It culminates in a chase and a shootout but concludes in an act of individual revenge on Wyoming’s highest mountain peak which calls to mind the work of James Stewart and Anthony Mann in their western collaborations. Most debut writer/directors make the mistake of filing every hole with overwritten dialogue: Sheridan is too shrewd for that. He allows the pictures to speak for themselves, human nature to assert itself as it usually does and the dead bodies are permitted testimony to their brutal demise. He chooses to end on a frame that expresses friendship and acceptance. (Followed by a piece of text which states that the only portion of the demographic not featured in Missing Person figures is Native American women.) It’s a very satisfying film – tense, character-driven, fast-moving and deeply felt – and it’s adorned with excellent performances and some beautifully mournful songs composed by Nick Cave and Warren Ellis.
