In addition to becoming just the fifth woman to be nominated for a Best Director Oscar — the others being Lina Wertmüller (“Seven Beauties”), Jane Campion (“The Piano”), Sofia Coppola (“Lost in Translation”) and Kathryn Bigelow (“The Hurt Locker”) — Gerwig became the first woman to be nominated for the award for her debut film. As far as entertainment awards go, Gerwig’s nomination is an important accomplishment.
