The film for Tuesday, 5 November will be “Los Olvidados” (1950). A powerful but unsentimental document of social problems, the story concerns poor children in a slum of Mexico City. Its approach has been compared to that of Italian neo-realism, but with elements of director Luis Buñuel’s distinctive sensibility. This is one of the great films Buñuel made during his residence in Mexico, and has received international acclaim. Buñuel’s own later work would develop a different sensibility, but “Los Olvidados” was widely influential.
