The usual make-up of the photoplay must strengthen this effect inasmuch as the wordlessness of the picture drama favors a certain simplification of the social conflicts.

The subtler shades of the motives naturally demand speech.

The later plays of Ibsen could hardly be transformed into photoplays.

Where words are missing the characters tend to become stereotyped and the motives to be deprived of their complexity.

The plot of the photoplay is usually based on the fundamental emotions which are common to all and which are understood by everybody.
