“Herman’s House” (90 min.) tells the story of Herman Wallace, who may be the longest-serving prisoner in solitary confinement in the United States—he’s spent more than 40 years in a 6-by-9-foot cell in Louisiana. Imprisoned in 1967 for a robbery he admits, he was subsequently sentenced to life for a killing he vehemently denies. When Herman meets artist Jackie Sumell, he finds a remarkable expression for his decades-long struggle. In this documentary by Angad Singh Bhalla we see the transformative power of art. The screening is a collaboration with POV, PBS’ award-winning nonfiction film series.
