Though the English-language title of this Austrian musical is Emperor Waltz, the film bears no relation to the 1948 Hollywood comedy of the same name. The story is that old chestnut about a lighthearted archduke who poses as his servant to see how the other half lives. In this guise, our hero falls in love with a commoner, a pretty schoolteacher. Will it be "Duty before Love," or the other way around this time? Austrian musicomedy favorite Rudolf Prack stars as the vacationing nobleman, while Winnie Markus co-stars as the schoolmarm. The songs are adapted from tunes written by Johan Strauss a century or so earlier. ~ Hal Erickson, Rovi
