Unsane

A young professional (Claire Foy), looking over her shoulder in a new town, tries to join a support group for stalking victims but finds that she’s checked herself into a mental clinic and can’t get out; soon she begins identifying one of the orderlies (Joshua Leonard) as the man who pursued her. Steven Soderbergh shot this psychological thriller with an iPhone 7, which gives the images a dim, lo-fi quality consistent with the 70s drive-in vibe of the story. Samuel Fuller’s Shock Corridor (1963), another thriller about a sane person trapped inside an asylum, must have provided Soderbergh with some inspiration as well, particularly in his semicomic treatment of the other patients (Jay Pharaoh as a laconic wise guy, Juno Temple playing against type in cornrows and a country accent). With Amy Irving.
