The artist, as embodied in the film director, translates his unique vision of the world and his individuality onto the cinema screen. The chief weapon in his employ is rhythm over time. The artist is imbued with a unique rhythm, a perspective on the world, and this "mark" is made upon each element of the film, from set design to dialogue to shot selection and editing. The artist uses his own rhythm, along with the natural rhythms of the subjects he is capturing, and then further shapes this rhythm in the editing room. The film artist is thus a sculptor of time, shaping reality-in-motion in order to reflect his unique worldview.
