Bringing up Boo

As part of its film series "Aspects of Mockingbird," which delves into "To Kill A Mockingbird" from all angles, the Adams Street Branch of the Boston Public Library will screen the Ira Wohl documentary "Best Boy" this afternoon. The Oscar-winning film follows an aging couple caring for their mentally retarded son, a story that may remind you of "Mockingbird" character Boo Radley. Next Wednesday, the library will show 2005's "Capote," which features Catherine Keener as "Mockingbird" author Harper Lee. Both films at 2 p.m. Free. Adams Street Branch, 690 Adams St., Dorchester, 617-436-6900. bpl.org
