Last week, the iconic American documentary filmmaker Ken Burns released his latest series: a six part, 12 hour film on the American revolution. The film follows dozens of figures from various backgrounds, allowing viewers to experience the war through the memories of the men and women who lived through it. Earlier this year, Burns was in Portland for a special sneak preview of the film. We listen back to his conversation with Geoff Norcross in front of an audience at Revolution Hall.
