Irish theater is top of mind locally, what with the warm-hearted Outside Mullingar continuing at Ensemble Theatre and this week an international festival of Irish acting. Catch daily performances of full-length Irish plays produced by companies from the U.S., Canada and Ireland — including our own Irish American Theater Company of Cincinnati, which is hosting the 22nd annual festival at its 200-seat theater. George Heslin, founder and artistic director of New York City’s Origin Theatre Company, critiques each day’s production and presents awards for directing, acting and production during a brunch on Sunday morning at downtown’s Millennium Hotel.
