Juliette Binoche balances cunning and vulnerability in this romantic cyber-drama turned psychological thriller from writer-director Safy Nebbou. Ghosted by her hunky twenty-something lover, Claire (Binoche), a middle-aged professor and single mom, creates a fake Facebook profile to do a little undetected online snooping. But when her 24-year-old avatar “Clara” is friended by her ex’s equally attractive roommate (François Civil), superficial correspondence quickly escalates towards intense intimacy and uncontrollable obsession. Adapted from Camille Laurens’ best-selling novel—and co-scripted by Julie Peyr, a regular collaborator of Arnaud Desplechin—Who YouThink I Am blends genres and bends reality to dizzying effect.
