Really, most great films not in English could be included. And silent films too. Some here (e.g The Band Wagon, Casque d’Or, Senso, Story of the Late Chrysanthemums, Tale of Tales..) may have a high reputation or have reached reasonable numbers of viewers but still deserve more fame or appreciation. The rest have certainly been hidden away or else, i think, are undervalued. Some TV now included.
