Blue Highways, Voices Of The Other America Directors: Nene Grignaffini, Francesco Conversano Running Time: 127 minutes Italy, 2004 Post Screening Discussion With Director       Loosely based on the novel of the same title by the American Indian writer, William Least Heat-Moon, Blue Highways is a trip into rural America. Blue Highways literally stands for the secondary roads indicated on maps in the 1950’s which connected smaller and more isolated communities and towns. The film is a trip through untouched landscapes, past old ghost towns and into today's malls and other such ‘non-places’. It is a fascinating portrait of rural America in the Bush era.       Screening: 28 October at 7.00 p.m.: Oxford Brookes
