‘The Last Days of Chez Nous’

Because its concerns are emotional, because its subject is the often devastating texture of ordinary life, the finely drawn “Chez Nous” takes a bit of getting used to. Films usually don’t try to be this honest about what people do to each other and, most especially, to those they nominally love. What drew director Gillian Armstrong back to her native Australia from Hollywood was novelist Helen Garner’s exceptional screenplay dealing with what looks to be a mildy eccentric family living a bohemian existence in contemporary Sydney. Although it starts out like a celebration, “Chez Nous,” starring Bruno Ganz and Kerry Fox (both pictured), turns inevitably into an examination of the way people grow apart, through nobody’s fault (Cinemax Wednesday at 5:30 a.m.).
