One of the most intensely personal entries in this year’s festival season saw Romanian director Kornél Mundruczó and his writer partner Kata Wéber draw on their own private life for Pieces of a Woman, in which Vanessa Kirby plays Martha, a first-time mother whose daughter dies in childbirth. Ellen Burstyn co-stars as Elizabeth, Martha’s mother, who leads the charge to prosecute the midwife present at the birth.
