Room

Jack is five, and the shed is the world because his mother has told him it is. Abrahamson keeps the first half inside that square, so the lamp and the skylight are characters. Brie Larson plays Ma as someone running a childhood and an escape at the same time. Jacob Tremblay has to believe both. The A24 trailer shows the rug and the truck. The film’s harder half is the house after they are out, where the world is too large to narrate.
