Monte Carlo is most famous for its delirious “Beyond the Blue Horizon” sequence, an image-and-sound symphony of whirring train wheels and landscapes flying past as a singing Jeanette MacDonald speeds across the French countryside. The story has countess MacDonald running off to the casinos of Monte Carlo in order to evade matrimony with a foppish prince. There a triangle develops when British gentleman Jack Buchanan poses as her hairdresser in order to gain entrance to her boudoir (the film develops a hair fetish worthy of Buñuel), and it all winds up with life imitating art as the plot resolution parallels a performance of the opera Monsieur Beaucaire. Claude Allister, as the asthmatic and prunefaced Prince Otto, is one of the cinema's greatest walking sight gags.
