The English-language title of Cantet’s Palme d’Or-winning film loses the texture and subtlety of the original French title, Entre les murs which means literally “Between the Walls.” The entire film takes place inside a tough, multi-ethnic inner-city Parisian middle school, which is both its challenge and its strength as it foregoes many of the assumed elements of the “inspirational teacher” genre and instead adopts an unadorned, documentary-like observational approach that creates dramatic energy without a tightly delineated storyline.
