It’s 2002, and willful Sacramento Catholic high schooler Christine (Saoirse Ronan)-or, to use her preferred affectation, “Lady Bird”-is just trying to get through the turbulent social waters of her senior year, and what she hopes are the last complicated, contentious months at home with her overworked, tough-loving hospital orderly mom (Laurie Metcalf). Writer/director Greta Gerwig’s acclaimed coming-of-age opus co-stars Tracy Letts, Lucas Hedges, Timothe Chalamet, Beanie Feldstein. 93 min. Widescreen; Soundtrack: English.
