Martin Scorsese said this quote

[Luchino] Visconti came from the Milanese branch of one of Europe’s oldest families, whose roots can be traced back to the early 13th century. He might have appeared as a character in one of his own films about the aristocracy, such as Senso or The Leopard – that’s the life he was born into. But at a certain point in the 1930s, his passion for theatre, opera and the cinema set him on a radically different path.(...)He has often been referred to as a great political artist, but that’s too limiting and frozen a description. His sense of European history was vast and he knew the lives of the rich and powerful first hand – but at a certain point he became drawn to understand the other side of life, that of the poor and powerless. He had a strong sense of the particular manner in which absolutely everyone, from the Sicilian fishermen in his neorealist classic La Terra Trema to the Venetian aristocrats in Senso, was affected by the grand movements of history.
