Imperial Cinema - The Prestige
An addition to the annals of Imperial Cinema that might have squeaked by, if I hadn't rewatched it during a bout of unemployment, is 2006's The Prestige. Directed by Christopher Nolan of Batman fame and based on a book by Christopher Priest, The Prestige is the story of two feuding magicians at the turn of the century.
Great movie overall, the kind that creeps up on you after a couple of viewings. There are a few great scenes where Hugh Jackman indulges in the imperial pint in a wonderful looking establishment. Also factoring into this story is a drunken actor, who cannot refuse a "very welcome pint of ale".
