Peering into obscure corners of Paris, Jean-Jacques Beineix emerged with an assembly of unlikely, even impossible, characters to populate his "Diva" (1981), a thriller that is more about how it looks than what happens in it. Here is an exhilarating film made for no better purpose than to surprise and fascinate. I remember it at Toronto 1981, where it arrived unknown and unsung and won, as I recall, the festival's first audience award. Now released in a restored print, it glistens in its original magnificence.
