One of the best contemporary war films I know is this singular 1988 feature, the first by Guinea-Bissau filmmaker Flora Gomes (Po di sangui). The first half, as elemental and as unadorned as Samuel Fuller’s The Steel Helmet, concentrates on women fighting alongside guerrillas at the end of Guinea-Bissau’s war of independence in 1973, attacked by Portuguese helicopters as they travel on foot close to the border. The second half, more diffuse and at times more rhetorical, deals with the ambiguous conditions of the war’s aftermath. The title means “those whom death refused,” and true to that notion the heroine (Bia Gomes) has been fighting for about a decade. Gomes (no relation to the director) manages to convey the loss of her children in a wordless and underplayed moment that shook me to my core. Flora Gomes appears in a cameo as president of a postwar sector. 93 min. Film Center, Saturday, August 12, 4:00, and Thursday, August 17, 6:00.
