Monte Carlo is a 1930 American pre-Code musical comedy film, directed by Ernst Lubitsch.

It co-stars Jack Buchanan as a French Count Rudolph Falliere masquerading as a hairdresser and Jeanette MacDonald as Countess Helene Mara.

Countess Helene Mara is about to be married to Duke Otto Von Liebenheim but leaves him at the altar.

She flees on a train to Monte Carlo with her maid Bertha (ZaSu Pitts) and 10,000 francs, and checks into an expensive hotel, planning to win a fortune at roulette.

She goes to his box to ask the question to his face, “Are you a hairdresser?” She is about to ask for his forgiveness, expecting to be rejected, as Lady Mary is by the incognito prince in the film's version of the opera.

They look out of the compartment door, singing “Beyond the Blue Horizon,” and are joined by a chorus of people in the fields they are passing.

The songs in the film were written by Richard Whiting and W. Franke Harling, with uncredited music by Karl Hajos, Herman Hand, Sigmund Krumgold, and John Leipold.

The best-known song in the film is "Beyond the Blue Horizon" by Richard A. Whiting and W. Franke Harling, with lyrics by Leo Robin.

Other songs in the film are: According to Variety "If it were not for Jeanette MacDonald there would be no picture, this despite the disappointing direction of Ernst Lubitsch and the talker debut of England's Jack Buchanan".
