Tomorrow night, I’ll be interviewing Michael Moore at a premiere screening of his new film, “Capitalism: A Love Story.” It comes 20 years after his “Roger & Me” changed the rules for documentaries in every category. He did not pretend to be balanced; he did not hesitate to be irreverent, even laugh-out-loud funny, and — related to the first two points — he shattered box office records. “Roger & Me” focused on the devastation in Moore’s home town of Flint, Michigan, in an economic downturn that seems modest by today’s standards. And Flint shows up again, in a twist that will give the audience goosebumps. Here is Moore on CNN this week. I’ll report on our session on Wednesday.
