Il Gattopardo by Giuseppe di Lampedusa (translated into English as The Leopard) is one of the finest novels I've ever read. And the film by Luchino Visconti (which I watched for the Nth time on television the other evening) is a masterpiece that has not aged one iota since it was made in 1963. Maybe I'm basically a sentimental and romantically-inclined old fellow. Be that as it may, the scene where Burt Lancaster waltzes with Claudia Cardinale moves me today to the same extent as when I first saw this movie, just after my arrival in France.
