Trivia

A silent version was produced for theaters not yet equipped for sound films. This version runs 20 minutes shorter than the sound version. The silent version was long thought lost until 1968. Historian and film preservationist David Shepard donated a copy, along with many other Paramount titles on nitrate film, to the American Film Institute.

The song "Beyond the Blue Horizon," introduced here, became Jeanette MacDonald's theme song for the rest of her life. During World War Ii she changed the line, "Beyond the blue horizon lies the rising sun" to " ... lies the shining sun" because the Rising Sun was the symbol of America's enemy, Japan.

Loosely based on the Booth Tarkington novel (1900) that was also source for the Rudolph Valentino drama Monsieur Beaucaire (1924) and the Bob Hope comedy Monsieur Beaucaire (1946). And there really is an English operetta (1918) based on the book, composed by André Messager, later adapted to French. It looks like recordings are only available for the French version. As of this writing (2017), both movies are available on DVD, but Valentino's looks like it's in public domain.

When Paramount requested approval starting in 1935 for the Pre Code Lubitsch titles to be rereleased, Monte Carlo was the only one that was not rejected by the newly installed Production Code.

One of over 700 Paramount productions, filmed between 1929 and 1949, which were sold to MCA/Universal in 1958 for television distribution, and have been owned and controlled by Universal ever since. Its earliest documented telecast took place in Minneapolis Saturday 25 July 1959 on WTCN (Channel 11); its initial Los Angeles telecast took place Friday 29 January 1960 on The Late Show on KNXT (Channel 2), and in New York City it first aired on the Late Show Monday 5 December 1960 on WCBS (Channel 2). Both of these last two particular slots were usually reserved for the most vintage titles in each station's Paramount Library. The restored version of this film was first released on DVD 12 February 2008 as one of 4 features in Criterion's Lubitsch Musicals collection, and has since enjoyed occasional presentations on Turner Classic Movies.
