Romanian director Cristian Mungiu, working with his first A-list cast (including an unrecognizable Sebastian Stan and Renate Reinsve), tells a provocative story about a conservative religious family accused of child abuse by their progressive neighbors. Fjord won this year’s Palme d’Or at the Cannes Film Festival, putting it immediately in the awards conversation; but the response to Mungiu’s challenging work has been divided at festivals like Telluride and Toronto this fall.
