For four decades Gunvor Nelson, a Swede who lived in the U.S. until 1993, has made work that explores both personal and larger issues. One major theme is the way our consciousness connects time and space, and in the affecting 1987 Light Years (one of three works screening at Chicago Filmmakers) landscapes seen from a moving vehicle evoke the artist's separation from her native land. In the 1984 Red Shift (Film Studies Center) fragments of Calamity Jane's letters combine with fragmentary figures to suggest the unknowability of others' lives. The lush flower and leaf close-ups in the finest work I previewed, True to Life (Chicago Filmmakers), never become pretty pictures, the continually moving camera pushing leaves aside and the rustling on the sound track depicting nature in terms of the artist's continuing journey. Nelson, now in her 70s, will attend both programs, and she says this is the last time she'll travel with her work. a Fri 11/17, 8 PM, Univ. of Chicago Film Studies Center; also Sat 11/18, 8 PM, Chicago Filmmakers.
