(CNN) Greta Gerwig has filmed a remake of "Little Women," Louisa May Alcott's classic book about four humble sisters named Meg, Jo, Beth, and Amy growing up outside Civil War--era Boston.

Vanity Fair offered a behind the scenes peek of the Massachusetts set, near where Alcott and her three sisters grew up. Gerwig heavily researched the locations she used, and carefully chose paintings and art to reflect the era.

Saoirse Ronan, who starred in Gerwig's debut as a solo director , 2017's Oscar-nominated "Lady Bird," plays Jo March.
