Let us … look at that land, where, although not perhaps its birthplace, the cinema found the soil in which to grow to unprecedented and unimagined dimensions.

We know from whence the cinema appeared first as a worldwide phenomenon. We know the inseparable link between the cinema and the industrial development of America. We know how production, art and literature reflect the capitalist breadth and construction of the United States of America. And we also know that American capitalism finds its sharpest and most expressive forms in the American cinema….

[Yet] in the [American] metropolis, … the high-powered automobiles are so jammed together that they can’t move much faster than snails creeping from block to block …. As you make your merely minute progress amidst a tightly packed glacier of other humans, sitting in similarly high-powered and imperceptibly moving machines, you have plenty of time to ponder the duality behind the dynamic face of America, and the profound interdependence of this duality in everybody and everything American…. as your eyes wander over the smooth surfaces of the skyscrapers …. you suddenly realize what “trick” the skyscrapers play on you: although they have many floors, each floor is quite low. Immediately the soaring skyscraper appears to have been built of a number of small-town buildings, piled up on top of each other….

The threads of both Americas are interwoven in the style and personality of [D.W.] Griffith–as in the most fantastic of his own parallel montage sequences.

On the dramatic stage the method of interpreting a theatrical production lies with the actor who expresses the theatrical idea through the creative will of the director and gives it individual form. In cinema, because of its unusually high technological component — the quintessence of the machine and electricity — and because of the surprising significance of montage, the actor takes second place. In view of the fact that cinema must be based on a purely external (i.e. visual) artistic influence on the public the cinema artiste must learn to create the required impression not just by acting with the face but by acting with the whole body; by an expressiveness of lines.
