Perhaps a more pertinent comment on film and media than the one from 1936 - or at least as pertinent - would be the Vatican II document “Decree on the means of social communication”. As far as film goes, look up the Vatican’s list of “45 Films of Note”, put out in 1995. You may be surprised at what the Vatican reccommends there - among them, for example, Nosferatu, the original Dracula film.
