I don't remember how, but once I've heard about a Michelangelo Antonioni trilogy of films: "La Notte" is one of them.
The film was shoot in the 60's, in a Milan who looks so intellectual and wealthy, so cosmopolitan and alive. The married couple are in a deep marriage crisis, they both know about the fact that they're cheating on the other. They are both totally bored about their life. Each on them is sure that, in a way, the other one suffers from the same kind of illness. That's why they never argue, one has pity the other.
Now I'm asking:
Could have Italy been so far ahead at that time? Maybe not, but the Antonioni was, and, in a way seems like is looking forward in time, in our time, to the mind of a contemporary man.
This is what I consider "AVANTGARD". The avantgard in art, music, cinema is the one who is meant to be ALWAYS so topical. What do you think about when you listen to a Beatles' album? I DO THINK it could be written nowadays.
