In the nightclub scene, the instrument in the center front of the band is labeled "Schunda V.J., Budapest". This instrument is a concert cimbalom designed by Vencel Jozsef Schunda in 1874. It is a box of metal strings that the cimbalist plays by striking two beaters against the strings. Simpler cimbaloms are commonly used in the folk music of Central Europe, but the concert cimbalom is especially popular in Hungary.
The Technicolor color director is listed as Natalie Kalmus. She is the wife of Herbert T. Kalmus, the co-founder and president of Technicolor Motion Picture Corp. Natalie was the color coordinator for nearly every live-action Technicolor feature film from 1934 to 1949. Studios often criticized her for insisting on too many neutral or muted colors.
Merle Oberon and Alexander Korda started a beautiful friendship on this movie, which often meant starting to rehearse by 12:30 p.m., followed quickly by lunch, which lasted until 3:30 p.m., which meant filming finished by 10 or 11 p.m.
In many scenes the actors seem to be saying the word "correspondent", but they are really saying "co-respondent". Under UK law, in a divorce petition on the grounds of adultery, a co-respondent is a person charged with misconduct with the petitioner's spouse. In other words, a co-respondent is a person with whom the spouse cheated.
