"My discovery of Tarkovsky's first film was like a miracle. Suddenly, I found myself standing at the door of a room the keys of which had, until then, never been given to me. It was a room I had always wanted to enter and where he was moving freely and fully at ease. I felt encouraged and stimulated: someone was expressing what I had always wanted to say without knowing how. Tarkovsky is for me the greatest, the one who invented a new language, true to the nature of film, as it captures life as a reflection, life as a dream." “When film is not a document, it is dream. That is why Tarkovsky is the greatest of them all. He moves with such naturalness in the room of dreams. He doesn’t explain. What should he explain anyhow? He is a spectator, capable of staging his visions in the most unwieldy but, in a way, the most willing of media. All my life I have hammered on the doors of the rooms in which he moves so naturally. Only a few times have I managed to creep inside.”
