Tarkovsky's goal in "Nostalghia," in terms of style, was to portray the soul, the memory, of Italy, of which it felt to him being there. When he visited Italy to begin studying the project of "Nostalghia" with Tonino Guerra, as they visited cities Tonino would show him Renaissance architecture, art, monuments, and he admired them, and would take notes, but what struck him the most was the sky, the blue sky, black sky, with clouds, with the sun, at dawn, at noon, in the evening. A sky, he said, is always simply just that, but a change in the hour of the day, the wind, climate, can have it speak to you in a different way, with love, violence, longing, fear, etc. Cinema, he said, can give these "ways" back to you and that it must, with courage, and honest, always starting from the real.
