Isabelle Huppert stars as a respected philosophy professor whose field of study comes in handy when her husband of many years, played by André Marcon, announces that he’s moving in with a younger woman. As if this weren’t enough, the professor’s mentally ill mother, played by Édith Scob, begins to go off the rails, requiring her constant attention. Written and directed by Mia Hansen-Løve (Eden, Goodbye, First Love), this French drama (2016) gives Huppert a brilliant, Rousseau-quoting character to play around with, and she saunters through the role, finding fresh moments in every scene. Hansen-Løve, almost three decades younger than her illustrious star, focuses on the professor’s relationships with young people—her two grown children; her lively and devoted students; a young writer who offers the vague prospect of May-December romance—and these contribute to Huppert’s portrait of a woman who, despite her advanced years, finds herself perched on the edge of discovery.
