In the film, silence can be extremely vivid and varied, for although it has no voice, it has very many expressions and gestures. A silent glance can speak volumes; its soundlessness makes it more expressive because the facial movements of a silent figure may explain the reason for the silence, make us feel its weight, its menace, its tension. In the film, silence does not halt action even for an instant and such silent action gives even silence a living face.
The physiognomy of men is more intense when they are silent. More than that, in silence even things drop their masks and seem to look at you with wide open eyes. If a sound film shows us any object surrounded by the noises of everyday life and then suddenly cuts out all sound and brings it up to us in isolated closeup, then the physiognomy of that object takes on a significance and tension that seems to provoke and invite the event which is to follow.
