"Koyaanisqatsi" (1983), directed by Godfrey Reggio. 87 minutes. No rating. For the art film devotees among us, a movie with visual splendor and a hauntingly rich score by composer Philip Glass. It first lulls with serene images of nature, then abruptly cuts to man's destructive influence over the very planet that sustains him. The title is Hopi Indian for "life out of balance."
