A documentary about the Nazi massacre of tens thousands of Jews at Babi Yar will air on Ukrainian National TV. “Spell Your Name,” a 90-minute film about the 1941 tragedy in Kiev, will air Thursday in prime time. It was co-produced by Steven Spielberg and Viktor Pinchuk, a Jewish Ukrainian business magnate. Following the documentary’s premiere in a Kiev theater last October, the producers promised to help Ukraine develop a new school textbook on Holocaust history that will be based on testimonies gathered by Spielberg’s Shoah Foundation. The textbook is expected to become available to Ukrainian schools in September.
