In Older Brother, Younger Sister, director Mikio Naruse's adaptation of an oft-filmed popular novel by Saisei Murô, the eldest daughter (Machiko Kyô) of a rural family comes home pregnant, testing some already tenuous family bonds. Naruse shows his considerable skill at portraying household dynamics, filming Kyô in relaxed and/or reclining positions (indicative of her character's exhaustively maintained independence) that are then intruded upon by her ill-tempered older brother (Masayuki Mori), whose initially comic, brute-force presence grows increasingly menacing and treacherous as the film progresses.
