Two of the greatest works by Catalan underground filmmaker Pere Portabella. The Franco-era black-and-white Umbracle (1970, 85 min.) is a provocation and protest composed of many dissimilar parts, ranging from Christopher Lee touring Barcelona to aggressive repetitions of sound and image. The more opulent, post-Franco color film Warsaw Bridge (1990, 85 min.) threads its own anthology of attractions (including operas, concerts, a lecture, a novel, a swank party, a forest fire, and sex) into something resembling a single narrative. Both are in Spanish and Catalan with subtitles. a Fri 11/17, 8 PM (Warsaw), Sat 11/18, 5 PM (Umbracle), Mon 11/20, 6 PM (Warsaw), and Wed 11/22, 8 PM (Umbracle), Gene Siskel Film Center.
