(AP Photo/Chris Pizzello)LOS ANGELES, Calif. – Laura Dern’s turn as a steely divorce attorney in “Marriage Story” made the case with Oscar jurors, who completed her awards season sweep by awarding her the best supporting actress trophy. Dern’s win Sunday came nearly three decades after her first Academy Award nomination, a lead actress bid in 1992 for “Rambling Rose.” She received a supporting actress nod in 2015 for “Wild,” and has earned Emmys and a wealth of critics’ honors over the years. I say if you’re really blessed, you get them as your parents,” an emotional Dern said in accepting the trophy. Dern comes from a pedigreed Hollywood family: father Bruce is a two-time Oscar nominee (“Coming Home,” “Nebraska”), and Ladd played her mom in “Rambling Rose” and earned her own Oscar nomination, for supporting actress.
