On Halloween the Arnold Arboretum was transformed back to the 1800s era in which it was created for the filming of "Little Women" starring Meryl Streep. Filming at the Arnold Arboretum was only scheduled for one day for the Columbia Pictures feature movie. It was not clear whether Streep was on set at the arboretum. For the filming, horse-drawn carriages and actors wearing Civil War era clothing were in the tree museum, which was created in 1872. It wasn't clear what scenes were being filmed of Louisa May Alcott's novel that is set in a New England town, and often believed to be based upon Concord, Mass.
