It's entirely possible that Abbas Kiarostami, who's been making films in Iran for about three decades, is our greatest living filmmaker. The problem isn't that his films are esoteric, simply that they're different from Western and other Iranian films alike, in the way they're put together (without scripts and in most cases without professional actors), in the way they address us, and in what Kiarostami includes and leaves out. Where Is the Friend's House? (1987, 85 min.), one of his most popular films in Iran, is a miniature epic about a schoolboy trying to return a classmate's notebook. Like the somewhat related Life and Nothing More (1992; also known as And Life Goes On . . .) and Through the Olive Trees (1994), both shot in the same section of northern Iran, this is a sustained meditation on singular landscapes and the way ordinary people live in them; an obsessional quest that takes on the contours of a parable; a concentrated inquiry that raises more questions than it answers; and a comic as well as cosmic poem. It's about making discoveries and cherishing what's in the world—including things that we can't understand. In Farsi with subtitles.
