Nader and Simin: A Separation by Asghar Farhadi is the Iran-made candidate for Best Foreign Picture at the Academy Awards. Not only is it a superb film with nary a wasted shot, but actors Leila Hatami and Peyman Maadi (they won the Best Actor awards at the last Berlin Film Festival) give three-dimensional, wholly believable performances as the two sides of an acrimonious couple going through a sloppy divorce.
