38 The problem of the production of moral films would be solved radically if it were possible for us to have production wholly inspired by the principles of Christian morality. We can never sufficiently praise all those who have dedicated themselves or who are to dedicate themselves to the noble cause of raising the standard of the motion picture to meet the needs of education and the requirements of the Christian conscience. For this purpose, they must make full use of the technical ability of experts and not permit the waste of effort and of money by the employment of amateurs.
