The process of art evolving is always one which has fascinated me.

Animation is manipulating the difference.

The number of strokes to the inch controls the pitch of the note: the more, the higher the pitch; the fewer, the lower the pitch, the size of the stroke controls the loudness... the tone quality is the most difficult element to control, it is made by the shape of the strokes.

Take a film of Jacques Tati like Mon Oncle which has something quite new - for me, unique - in it.

Unless it's done superbly, as in the Japanese film Gate of Hell, color can be a very distracting element.

In any art movement, the art has to move into a new phase - a filmmaker has a desire to make a film that is not like a previous film.

I have tried to preserve in my relationship to the film the same closeness and intimacy that exists between a painter and his canvas.
