7.  Centralizing the Interest

It is almost impossible to produce a really effective photoplay without centering the attention of the spectator on one of the principal characters and holding it there until the end.  Even when the principal characters are lovers, either one or the other is bound to stand out in the picture more than the other.  As in a play on the regular stage, either the hero or the heroine must dominate the action or the spectator is very likely to miss some of the best points of the plot because of the shifting interest.  In such a play as “Romeo and Juliet,” many would find it difficult to determine which of the two principal characters evokes the more sympathy and interest in the spectators.  Yet a careful study of the play will leave no doubt that it was Shakespeare’s intention that one of the two “star-crossed lovers”—­Juliet—­should dominate the action of the drama very subtly and certainly, the other being, though in only the slightest degree, it is true, subordinate to the “principal.”  The same thing is true in the stories of Damon and Pythias, Paolo and Francesca, and Pelleas and Melisande.  You must determine at the very beginning whether it is to be the man or the woman, and, having trained the spot-light upon that one, keep it there until the end.

A certain picture, released about four years ago by a European manufacturer, was concerned with a husband, his wife, and his friend—­a man who for a period of some months was a guest in the home of the pair.  In the ordinary sense, it was not a problem plot; the friend was an honorable man, and the husband, who had the most sincere admiration for his old college companion, was a fine fellow in every way.  Yet, as the story progressed it became apparent that there had been a love affair between the wife and her husband’s friend when they were both scarcely more than children.  Little incidents in the action of the next few scenes gradually caused the audience to sympathize with the friend.  Then, toward the end of the play, the sympathy was definitely shifted to the husband.  This, of course, viewed in the proper light, was as it should be; but only a scene or two from the end of the picture an incident happened that again caused the audience to feel that it was the friend who alone deserved the woman’s love.  The result was that out of all the hundreds of people who saw the picture in the two days during which it was shown at a certain theatre, none expressed themselves as being satisfied with it, although only a few were able to say directly that they did not approve of the play because of the frequently shifted interest.

Thus the picture failed because whoever wrote it did not keep in mind the important fact that divided interest will go a long way toward destroying the dramatic value of any story, regardless of how perfect it may be otherwise.

Use as few principals as possible, no matter how many minor characters or extra people are employed; and be sure to keep the subordinate characters in the background sufficiently to prevent them from detracting in any way from the interest that should be constantly fixed upon your principals, and especially the two principals who make possible nine-tenths of all the stories written.
