Prince Karl Franz of Karlsburg (Edmund Purdom, looking like a rugged Montgomery Clift) – a “Prussian pickle” – is spoiled, stubborn, petulant and haughty but vulnerable to the lessons of democratic behaviour that barmaid Kathie (Ann Blyth) is in a position to teach him.
Kathie is the daintiest, most aristocratic-looking, musically-inclined barmaid imaginable, and Prince Karl learns more from her than from the entire faculty of Old Heidelberg.
In featured roles are John Ericson, Louis Calhern, Edmund Gwenn, SZ Sakall, Betta St. John, John Williams and Evelyn Varden.
Even with the CinemaScope, the colour, the modified story, and the new songs, Romberg’s lilting melodies remain pretty much the film’s highlight.
MGM made no secret that Mario Lanza was singing for Edmund Perdom in the title role. Originally cast in the part, Lanza was too fat by the time filming began. Ann Blyth used her own pleasant soprano.
