I recently saw Antonioni's L'Eclisse (1962) and was profoundly moved by it. In the above clip Martin Scorsese discusses the film, particularly the ending. L'Elcisse stars Monica Vitti and Alain Delon.
This is unconventional story-telling, leaving, as it does, so much space. L'Eclisse is wonderfully uncluttered with dialogue or traditional plot points. It is an invitation into a time and place among a few characters. This is a film that is as beautiful as its two co-stars.
Scorsese's discussion highlights much of what is so special about L'Eclisse.
