Jo March once grumbled while lying on a rug that Christmas wouldn’t be Christmas without any presents. Luckily, Sony Pictures dropped a trailer Tuesday afternoon reminding everyone of the holiday present that awaits us all: Greta Gerwig’s adaptation of Louisa May Alcott’s “Little Women,” due for a Dec. 25 release. The film, which reunites Gerwig with “Lady Bird” actors Saoirse Ronan and Timothée Chalamet, also stars Meryl Streep, Laura Dern, Florence Pugh, Emma Watson and Eliza Scanlen.
