"The beauty and genius of a work of film
may be reconceived, though its first material expression be destroyed; a vanished fiction
may yet again inspire the screenplay-writer
; but when the last individual of a race of living directors, of artists,
breathes no more, another heaven and another earth must pass before such a one can be again." -William Beebe, modified in memorial of the twentieth century
