Lilian Harvey, the toast of two continents, is her usual radiant self in Invitation to the Waltz. Harvey plays Jenny Peachey (honest!), a Drury Lane ballerina during the Napoleonic Wars. Swept off her slippers by the handsome Duke of Wurtemberg (Harold Warrender), Jenny gives up her dancing career to become the Duke's mistress. As the war between England and France intensifies, our heroine uses her influence to persuade the Duke to sign a treaty with England, thereby helping to bring about the downfall of Napoleon (Esme Percy). Through it all, Jenny is worshipped from afar by handsome Lieutenant Carl (Carl Esmond). Magnificently produced, Invitation to the Waltz was a lighthearted follow-up to Lillian Harvey's more serious "ballerina sacrifices all" opus, Schwartze Rosen.
