Although the assembly of the shots is responsible for the structure of the film, it does not, as is generally assumed, create its rhythm; the distinct time running through the shots makes the rhythm of the picture, and the rhythm is determined not by the length of edited pieces, but by the pressure of the time that runs through them. The pieces that 'won't edit', that can't be properly joined, are those which record a radically different kind of time
Andrei TarkovskyI'VE NOTICED, FROM MY EXPERIENCE, IF THE EXTERNAL, EMOTIONAL CONSTRUCTION OF IMAGES IN A FILM ARE BASED ON THE FILMMAKER'S OWN MEMORY, ON THE KINSHIP OF ONE'S PERSONAL EXPERIENCE WITH THE FABRIC OF THE FILM, THEN THE FILM WILL HAVE THE POWER TO AFFECT THOSE WHO SEE IT.
