A high point of Iran's first new wave, this 1965 masterpiece by Ebrahim Golestan takes its title from the classical Persian poet Sa'adi, who wrote, "What the old can see in a mud brick, youth can see in a mirror." The philosophical implications of this are fully apparent in Golestan's tale of a young man who finds a baby girl in his cab and spends a night with his girlfriend debating what to do with the infant. Though this black-and-white 'Scope film superficially resembles Italian neorealism, especially in its indelible look at Tehran street life and nightlife in the 60s, its spirit is a mix of Dostoyevsky and expressionism: minor characters periodically step forward to deliver anguished soliloquies, contributing to an overall lament both physical and metaphysical. In Farsi with subtitles. 124 min. Golestan will take part in a discussion after the Saturday screening. Reviewed this week in Section 1. a Sat 5/5, 7:45 PM, and Thu 5/10, 6 PM, Gene Siskel Film Center.
