No Country for Old Men (2007)

Cautionary thriller. A hunter in 1980 West Texas stumbles on a drug deal gone wrong and a case holding $2 million, and his choice to take it brings Javier Bardem's Anton Chigurh after him. The Coen brothers' Cormac McCarthy adaptation won four Oscars, Best Picture among them. It belongs here because it is the bleakest answer on the list: Josh Brolin plays Llewelyn Moss as capable and careful, and the tension comes from watching a sensible man take one reckless chance. Long silences and sudden violence make it the opposite of a comfort watch, but nothing else captures so well how found money can belong to someone who wants it back.
