The most hardcore thriller in years, Jeremy Saulnier’s follow-up to 2013’s critically acclaimed Blue Ruin is another exercise in extreme, nail-biting suspense, this time about a just-scraping-by punk band (comprised of the late Anton Yelchin, Alia Shawkat, Joe Cole, and Callum Turner) that unwisely decides to accept a gig at a rural neo-Nazi music club. When they happen to witness the aftermath of a murder, they become captives of the resident skinheads and their leader (a terrifying Patrick Stewart), leading to a prolonged showdown which Saulnier stages as a series of quiet, panic-stricken moments and bursts of brutal violence—a storytelling rhythm in tune with the sludgy punk and metal thundering through the venue’s speakers. A relentless assault on one’s nerves that pummels viewers with the same all-out viciousness exhibited by the racists slam-dancing around the venue’s grimy, beer-soaked floors, Green Room (which we dubbed “mosh-pit cinema”) leaves a lasting mark.
