The greatest director in the history of black cinema is Charles Burnett. His greatness rests on two films: Killer of Sheep (1977) and To Sleep with Anger (1990). Between these films is My Brother’s Wedding (1983). The first is an urban poem imbued with the humanism of the blues; the third is a work of philosophy that draws from the cosmic hum of gospel. The middle film is the bridge from the first masterpiece to the second. It’s not, to be honest, an outstanding film, but it does bring us closer to the outstanding mind behind Sheep and Anger. Tonight’s screening is part of NWFF’s monthlong series LA Rebellion, and the director will be in attendance. (Northwest Film Forum, 1515 12th Ave,, 8 pm, $10)
