Filmmaker Michael Moore was in downtown Chicago over the weekend for an advance screening of his latest documentary, “Capitalism: A Love Story,” which opens nationwide this Friday. The audience included dozens of laid-off Republic Windows and Doors employees. Their sit-in at the company‘s Chicago plant last December earned them a leading role in the film. After the screening, Moore took audience questions. This 16-minute excerpt begins with him recalling his crew’s reaction to a press release from the workers’ union, the United Electrical Workers, on the first day of the sit-in. audio
