Walter Julius Bloem, The soul of the moving picture (1924)
“ The film author’s place is in the studio; he should be the silent witness of every scene; he should be thoroughly conversant with such technical progress as has been made and is being made in the way of illumination and psychic photography. But he dare never forget that a film work is not the work of an individual.An author has to have, if success is to crown his efforts, a great store of general information, a store such as reaches far out beyond the studio. He should have a general but clear idea as to what it costs to mount a film. ”
