This unity of action involves unity of characters. It has too often been maintained by those who theorize on the photoplay that the development of character is the special task of the drama, while the photoplay, which lacks words, must be satisfied with types. Probably this is only a reflection of the crude state which most photoplays of today have not outgrown. Internally, there is no reason why the means of the photoplay should not allow a rather subtle depicting of complex character. But the chief demand is that the characters remain consistent, that the action be developed according to inner necessity and that the characters themselves be in harmony with the central idea of the plot. However, as soon as we insist on unity we have no right to think only of the action which gives the content of the play. We cannot make light of the form. As in music the melody and rhythms belong together, as in painting not every color combination suits every subject, and as in poetry not every stanza would agree with every idea, so the photoplay must bring action and pictorial expression into perfect harmony. But this demand repeats itself in every single picture. We take it for granted that the painter balances perfectly the forms in his painting, groups them so that an internal symmetry can be felt and that the lines and curves and colors blend into a unity. Every single picture of the sixteen thousand which are shown to us in one reel ought to be treated with this respect of the pictorial artist for the unity of the forms. _The photoplay shows us a significant conflict of human actions in moving pictures which, freed from the physical forms of space, time, and causality, are adjusted to the free play of our mental experiences and which reach complete isolation from the practical world through the perfect unity of plot and pictorial appearance._ CHAPTER X THE DEMANDS OF THE PHOTOPLAY
