“You want them to pay? You have to be lucid, cool, precise. You go there, you see, and you take—that’s payback.” Arthur Harari’s first feature is a poised, stylish, and utterly assured revenge thriller in which violence erupts suddenly amid tense, hushed stretches of talk. Pier Ulmann (Niels Schneider) comes from a family of powerful diamond dealers based in Anvers. After his estranged father’s death, he vows vengeance against his relatives who had abandoned him and returns to the business with an elaborate robbery in mind. Featuring menacing tracking shots; a cool, metallic color palette; surprising third-act reversals; and a terrific ensemble cast, Dark Inclusion is a movie precisely attuned to the logistical and moral complexities that accompany lives of luxurious crime.
