The Leopard is being re-released by the BFI this week in a new digital restoration. Luchino Visconti’s adaptation of Giuseppe Tomasi di Lampedusa’s great Sicilian novel was first seen in 1963 and went on to win the Palme d’Or at Cannes. Il Gattopardo, to give it its Italian name, charts the decline of the house of Salina, a once mighty clan of Sicilian nobles who watch their power slip away as Garibaldi drags 19th-century Italy toward unity and modernity. But alongside the political narrative, book and film give a starring role to another timeless Italian reality: food.
