When a friend asked if it was realistic that Asghar Farhadi’s new, Oscar-nominated “The Salesman” shows an Iranian company staging Arthur Miller’s “Death of a Salesman”-a play by an American Jew-I replied that such things are common, as are presentations of works by Americans such as Tennessee Williams, Edward Albee and Sam Shepard. While Iran, uniquely in its region, has not only an indigenous form of traditional theater (Ta’ziyeh) but also a strong modernist descendant that includes such monumental talents as writer-director (and filmmaker) Bahram Beyzaie, Tehran also sees frequent stagings of works by playwrights including Ionesco, Beckett and Pinter. Theater is also a lively center of cultural action.
