It’s not an easy task to adapt one of the most famous American novels of all time for the screen. Not only has Louisa May Alcott’s “Little Women” been beloved since it was first published in 1868, it has also had several well-regarded film adaptations before, starring actresses like Katharine Hepburn and Winona Ryder. And yet, if anyone was going to take on this mammoth task, Greta Gerwig seems like the perfect person. Gerwig broke onto the directing scene in 2017 with her first film, “Lady Bird,” a coming-of-age story starring Saoirse Ronan. She returns this year with one of the most iconic female coming-of-age stories of all time, “Little Women,” refreshed and updated for a modern audience without losing any of the spirit of the book -- and once again starring Saoirse Ronan.
