32 Moreover, stories and actions are presented, through the cinema, by men and women whose natural gifts are increased by training and embellished by every known art, in a manner which may possibly become an additional source of corruption, especially to the young. Further, the motion picture has enlisted in its service luxurious appointments, pleasing music, the vigour of realism, every form of whim and fancy. For this very reason, it attracts and fascinates particularly the young, the adolescent, and even the child. Thus at the very age when the moral sense is being formed and when the notions and sentiments of justice and rectitude, of duty and obligation and of ideals of life are being developed, the motion picture with its direct propaganda assumes a position of commanding influence.
