Iranian cinema is about to get a whole lot more interesting with Asghar Farhadi’s “Nader & Simin: A separation,” which in theory should be shown in limited release in about two months in the U.S.

Shot in semi-clandestinity in Tehran, it tells the tale of a couple, on the verge of separation, who are ripped apart by a parent’s Alzheimer’s disease and a caretaker hired to help him make it through the debilitating disease. Class differences and the slow disintegration of the couple’s life seem to be the order of the day in this narrative.
