Tony winner John Cullum will join the Broadway cast of August: Osage County on September 16 as patriarch Beverly Weston for eight performances, according to The New York Times, replacing a vacationing Michael McGuire. No word on whether Cullum might assume the role full-time when McGuire departs for the London production of Tracy Letts' Tony-winning play, which begins performances at the National Theatre on November 21.
Cullum won Tony Awards for Shenandoah and On the Twentieth Century and received Tony nominations for 110 in the Shade, Urinetown and On a Clear Day You Can See Forever. Last season, he appeared in Lincoln Center Theater's Broadway production of Cymbeline and played President Lyndon Johnson in The Conscientious Objector for Keen Company. Known for his TV role as Holling in Northern Exposure, Cullum has appeared as Attorney Moredock in Law & Order: SVU and as a tobacco company executive in the pilot episode of Mad Men.
