This 35mm screening is part of the Cinematic Jukebox strand at the Prince Charles Cinema. You can find all the details of the season here.
Luchino Visconti's The Leopard is a bona fide masterpiece which grows in stature with the passing years and now in a remastered print which simply adds to the beauty of a magisterial work of cinema.
Here is critic Dave Kehr on the film's history, it was butchered on release and only seen in a truncated form for many years, and here is Martin Scorsese talking about his involvement in the restoration. The Leopard is one of the American director's favourite films as evidenced in this list.
Chicago Reader review:
Cut, dubbed, and printed in an inferior color process, the U.S. release of Luchino Visconti's epic didn't leave much of an impression in 1963; 20 years later, a restoration of the much longer Italian version revealed this as not only Visconti's greatest film but a work that transcends its creator, achieving a sensitivity and intelligence without parallel in his other films. Burt Lancaster initiated his formidable mature period as the aging aristocrat Don Fabrizio, who works to find a place for himself and his family values in the new Italy being organized in the 1860s. The film's superb first two hours, which weave social and historical themes into rich personal drama, turn out to be only a prelude to the magnificent final hour—an extended ballroom sequence that leaves history behind to become one of the most moving meditations on individual mortality in the history of the cinema. With Alain Delon and Claudia Cardinale. In Italian with subtitles.
