Blue Danube on AllMovie

Cecil B. DeMille functioned as executive producer for the derivative romantic melodrama The Blue Danube. Leatrice Joy stars as Marguerite, a Budapest tavern girl, who falls in love with young baron Erich (Nils Asther). When WWI breaks out, Erich is called back to his regiment on the eve of his wedding to Marguerite. This provides a golden opportunity for Ludwig (Joseph Schildkraut), a deformed, embittered violinist who is secretly in love with the heroine. Intercepting her mail, Ludwig convinces Marguerite that Erich has been unfaithful, whereupon the girl agrees to marry the violinist on the rebound. Only the unexpected return of Erich prevents villainy from triumphing over virtue. The Blue Danube was written by future director John Farrow.
