Can you call something a moving picture if it doesn’t actually move? That’s the question at the root of Moore College’s current exhibition, “The Long Now,” which features a series of films that blur the distinction between still and motion pictures. Of course, no one has posed that question with quite the provocation of Andy Warhol, whose infamous Empire (1964, pictured) — an eight-hour time-lapse shot of the titular NYC landmark — will screen on Oct 3. Other films on offer aren’t quite such endurance tests. The single tracking shot of Michael Snow’s pivotal Wavelength may test patience, but only for 45 minutes. And while Chantal Akerman’s 200-minute Jeanne Dielman, 23 quai du Commerce, 1080 Bruxelles earned her a bio entitled Nothing Happens, quite a lot actually does; her masterpiece is, essentially, a melodrama, just one that is compelling because of its refusal to look away from the minutiae.
