“Red Hope? the Blacklisting of Hope Foye,” which is nominated for best documentary at the Pan African Film Festival, tells the story of how soprano Hope Foye, was forced to live in exile because of the McCarthy-era interrogations she endured by the House Un-American Activities Committee. An early activist who fled to Mexico and later Europe, the 87-year-old Foye will be at the festival during the screenings of the Constance Jackson documentary on her life: Feb. 20 (6:15 p.m.) and Feb. 22, 1:30 p.m. at the Culver Plaza Theatre.
