This is limited to what i saw, which is a small part of Italian cinema :)
A bit sad bit i love a lot its aesthetics and the psychology
This represents well the traditional south, it was shot in the area of Sicily i come from
Brilliant collection of small episodies about italian weaknesses
This represents a true cult for Tuscans
This is a movie about Sicily passing from Spanish Bourbons to the Italian republic, and from aristocracy to bourgeoisie. Visconti features stunning photography and aesthetics and a maniacal attention for the details. This became a true cult in defining Sicilian and southern identity, see this quote
Totò is a principal charachter in defining the Italian stereotype. I do not know his movies very well, but this one is funny and representative
