French-German co production of a Viennese subject.
Pleasant enough largely songless (the leads get solos) operetta.
In a period of diplomatic maneuvering between Vienna and Munich German cavalry officer Garat's park land gallantry with Parely is mistaken for an engagement getting in the way of his courtship of her Sister, pastry chef St. Cyr.
This slim plot is submerged in elaborate costuming and impressive decors from Rohrig & Herlth. Gremillon is right out of his element but doesn't disgrace himself, filling the screen with movement and staging in depth. The actual Valse Royale is a passably spectacular set piece giving the film it's tone.
