狗·星·人：第三部分 (1964)

Sexual intimacy. Three kinds of images race past, superimposed on each other sometimes: two bodies, a man and a woman's, close up, nude - patches of skin, wisps of hair, glimpses of a face and genitalia; strips of celluloid with lines and squiggles scratched on them; and, close-up shots of what appear to be the insides of living bodies - a heart beating, muscle and sinew and tissue wet with fluids. The exterior and interior of desire.
