This is a great documentary from the brother of Bernardo Bertolucci. Is about real people wandering in the Central Train Station in Milan. The construction of the movie is original cause the real people moves in front at the camera same time like actors (guided by Bertolucci in an invisible way) but telling their own stories...Really powerful and moving...It's a sin is not available in any form...video or DVD...and last time was passed in Italian TV was 10 years ago....a true document about people that has the suffering in their words and bodies. The stories are mixed and reunited in little chapter, take a look to another beautiful and intelligent documentary of Giuseppe Bertolucci about drug, called "Il perché e il percome"
