Griffith, 1916), author Eustace Ball, in the volume "The Art of the Photoplay" advised, "Put one plot at a time; the single reel picture lasts only eighteen minutes and only one line can be worked out well in this time. This is another important detail in which the photplay differs from the drama." D. W. Griffith Victor Sjostrom
