“Bergman, in effect, is the film-maker of the instant. Each of his films is born of the hero’s reflection on the present moment, and deepens that reflection by a sort of dislocation of time–rather in the manner of Proust but more powerfully, as though Proust were multiplied by both Joyce and Rousseau–to become a vast, limitless meditation upon the instantaneous. An Ingmar Bergman film is, if you like, one twenty-fourth of a second metamorphosed and expanded over an hour and a half. It is the world between two blinks of the eyelids, the sadness between two heart-beats, the gaiety between two handclaps.” –Jean-Luc Godard
