When Michael Moore makes his appearance at a special Mavericks event during the upcoming Toronto International Film Festival next month, he'll also be showing clips from two works-in-progress, according to the festival's Doc Blog. During the session, Moore will offer glimpses of both his upcoming health care film "Sicko" and segments from his secret new film, "The Great 04 Slacker Uprising," which the festival describes as "a scrappy road trip movie following his two months of daily campaigning against George W. Bush in the 2004 election." The fests Doc Blog also includes a remembrance from John Pierson, who shepherded Moore and his "Roger and Me" to the fest back in 1989 when the director won the audience award and launched his career.
