I may have said something about it, can't remember very well, but anyway, can't surpass Anasazie's review which summarizes it just about perfectly. Yes, i was going to say ethereal too. And add that Rivette has a peculiar ability to stretch time in unusual ways- not just through the length of his films, but a mysterious indefinable something at work, an elusive other-worldly quality even when ghosts or revenants are not involved. (As they are too in Celine + Julie as it happens). So clocks seem very appropriate here. Did you notice the veins sticking out in Bart's forehead in a sex scene; no wonder she said she was exhausted; no soppy, trying so hard to be sexy Hollywood oohing, aaahing, panting, grandstanding here- Rivette clearly meant business and no amount of acting could replicate her expression.
