After trapping Michael Fassbender’s head inside a large papier-mâché mask in last year’s Frank, director Lenny Abrahamson has decided to give Brie Larson a little more wiggle room with an adaptation of Emma Donoghue’s best-selling novel, Room. The film follows Larson’s Ma and her 5-year-old son Jack (Jacob Tremblay), who are being held against their will in a small 10-by-10-foot shed. Jack has never known life outside of the enclosed living quarters, so Ma does the best she can to keep his hope and imagination alive while secretly plotting their escape. Room opens in Chicago on October 23, but The A.V. Club and A24 have an opportunity for you to see it for free on October 21.

“Room tells the extraordinary story of Jack (Jacob Tremblay), a spirited 5-year-old who is looked after by his loving and devoted Ma (Brie Larson). Like any good mother, Ma dedicates herself to keeping Jack happy and safe, nurturing him with warmth and love and doing typical things like playing games and telling stories. Their life, however, is anything but typical—they are trapped—confined to a windowless, 10-by-10-foot space, which Ma has euphemistically named “Room.” Ma has created a whole universe for Jack within Room, and she will stop at nothing to ensure that, even in this treacherous environment, Jack is able to live a complete and fulfilling life. But as Jack’s curiosity about their situation grows, and Ma’s resilience reaches its breaking point, they enact a risky plan to escape, ultimately bringing them face-to-face with what may turn out to be the scariest thing yet: the real world.”
