"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." "Fright Night" (1985), directed by Tim Holland. 105 minutes. Rated R. Scary, funny and intentionally campy, "Fright Night" revolves around a teen-ager who thinks his new next door neighbor is a vampire. Chris Sarandon makes a wisecracking, smug resident Dracula, and Roddy McDowall plays "The Great Vampire Killer" with verve. A perfect mix of comedy and chills.
