The Photoplay [EPUB ebook] 

Do the photoplays furnish us only a photographic reproduction of a stage performance; is their aim thus simply to be an inexpensive substitute for the real theater, and is their esthetic standing accordingly far below that of the true dramatic art, related to it as the photograph of a painting to the original canvas of the master? Or do the moving pictures bring us an independent art, controlled by esthetic laws of its own, working with mental appeals which are fundamentally different from those of the theater, with a sphere of its own and with ideal aims of its own?
