Andrei Tarkovsky Quote

What is the essence of the director's work? We could define it as sculpting in time. Just as a sculptor takes a lump of marble, and, inwardly conscious of the features of his finished piece, removes everything that is not a part of it — so the film-maker, from a 'lump of time' made up of an enormous, solid cluster of living facts, cuts off and discards whatever he does not need, leaving only what is to be an element of the finished film, what will prove to be integral to the cinematic image.
