Michael Moore was considered to be an abrasive filmmaker who staged a frontal assault on the free-enterprise system in one of his films.
Moore's recent film entry this year is "not a sortie against a particular industry. It is a frontal assault on the very idea of American free enterprise; a beast," he called it in a rabble-rousing speech to an audience in Toronto, Canada.
