Trivia

This was MGM's first full-length feature in three-strip Technicolor. As such, viewers can see the constant shift in quality between scenes, chiefly in the makeup, which often appears garish and overstated. One short year later, the process would be perfected in time for The Wizard of Oz (1939) and Gone With the Wind (1939).

This is MGM's first full-length film to feature a different lion roaring in the logo, by the name of Tanner. He appeared at the beginning of MGM's Technicolor feature films and cartoons from 1936 to1956 and later, from 1963 to 1967.

The large set that Nelson Eddy and Jeanette MacDonald perform the title song on is a piece of the dismantled set from the "Pretty Girl Is Like a Melody" number from The Great Ziegfeld (1936). This set piece was later used in Two Girls on Broadway (1940) and Ziegfeld Girl (1941) among other films.

One of the Times Square marquees is advertising the play "Idiot's Delight" starring Alfred Lunt and Lynn Fontanne for which MGM had just purchased the film rights.

The lavish musical number that was staged for the title song, re-uses the enormous, reticulated descending silk curtain that was originally created for the 'Pretty Girl Is Like a Melody' number in "The Great Ziegfeld" in 1936. This remarkable, custom-made artifact was also later used in "Babes on Broadway" (closing number) and "Lady be Good" (closing number).
