"I think cinema is the only art that operates within the concept of temporality. Not because of its developing in time; there are also other art forms that do so: ballet, music, theatre. I mean `time' in he literal sense of the word. What is a take, from the moment we say `action' till the moment we say `stop'? It is the fixing of reality, the essence of time, a way of preserving time which allow to roll and unroll it forever. No other form of art can do that. Therefore, cinema is a mosaic made of time."

Andrei Tarkovsky
