But best of all is the film's last forty minutes or so, the entirety of which is devoted to a ball at Donnafugata, which the Prince and all his entourage attend. It's as beautifully shot as you'd expect - the lushness of the costumes and the decor, of the food and the music - but it is the searing melancholia these sequences inspire in the viewer which will stay with you, which made it (as one newspaper put it) "almost unbearably moving". Fabrizio, aware that his own aristocratic Italy will pass away soon and needs must become something new, walks mournfully from room to room, looking at himself in mirrors and his eyes starting to well up. He is offered one last waltz with Angelica, the fiancée of his nephew Tancredi; he gratefully accepts, and for a few minutes he feels young again, is once more invigorated... and then the evening is over, and he walks home alone. Lancaster sells the emotional highs and lows of this sequence brilliantly (alongside a charismatic, and stunning, Claudia Cardinale as Angelica), making it arguably one of the greatest sequences ever committed to film. It's topped off by Fabrizio's underplayed, prosaic, perfectly apposite line of dialogue: "I'm a bit tired, but I'm here now, so I have to stay. It would be rude to leave."
10/10 - essential viewing.
