This understated but affecting 2002 drama, which director Mahamat-Saleh Haroun says is one of just three features ever made in Chad, should be required viewing for American kids who think they’ve got troubles. The father of two boys disappears; the mother, unable to cope, enrolls the boys in a remote and harsh Islamic school. Haroun’s delineation of their isolation through small, finely observed incidents supports comparisons to the work of Abbas Kiarostami. The starkly elegant compositions underline the existential nature of the brothers’ plight: it will be entirely up to them to make something of their lives. In Arabic and French with subtitles. 84 min.
