Nino Pezzella’s new untitled 15-minute film consists of a short, enigmatic string of images repeated in the same order 44 times. That the images appear in the same order and for the same length of time in each cycle is not apparent at first, because their appearances vary with each repetition. They are seen negative or positive, darker or brighter, in varying tints. An image that at first seems totally black reveals specks of light over repeated viewings and eventually becomes a night view of boats in a harbor. The sound track starts sparsely, but soon develops into a simple percussive rhythm, accompanied by two steadier tones, that’s repeated twice in each cycle. But none of this description conveys the film’s powerful, haunting, even scary effect. The enigmatic images–a sheep being slaughtered, a sphinxlike shape with a superimposed moon, several corpselike figures, a crucifix–are presented rhythmically, as if what we are seeing is the unknown language of some lost civilzation or the secret rituals of some unknown religion. It is as if these images represent some fundamental order underlying all things. It’s apparent from the other two films of his on this program (Mia Zia and The Body Is My Temple) that Pezzella, who grew up in Italy and Germany, is interested in religion. But there is no single God in this film, only the strange associations and shifting perceptions engendered by the ever-changing imagery. The program also includes several films by Chicagoans Hal Marshall and Mark Nugent; the three artists will be present. (Chicago Filmmakers, 1229 W. Belmont, Friday, April 3, 8:00, 281-8788.)
