"Chronicle of A Summer" invented the cinema verité movement, the idea being that by celebrating and revealing the artificial nature of the film-making process, the truth, or more accurately, some truths will emerge. The film is enveloped with a luminous and appealing humanism, and it is a very cool and cinematic portrait of Paris in the beat days. Remember that World War Two was only a decade or so before this and somehow the fog of that war hangs over the film, especially given the backstory of one of the participants, at least this is what I remember..As historic documents go, it is also amazingly compelling today. I find the film much more absorbing than "Salesman" or Drew Associates stuff. Drink espresso instead of a pint before the film, my friend and you'll be fine..
PS If you want to watch paint dry, check out Melville- Although he's pretty great too..
