As originally filmed, Carlotta's dog was named Mussolini. However, due to the changing world political climate of the 1930's, the dog's name was post-dubbed as "Tarzan", even though Marie Dressler's lips are clearly saying "Mussolini".
The dowager character played by Marie Dressler is reportedly based on actress Mrs. Patrick Campbell, for whom George Bernard Shaw wrote the role of Eliza Doolittle in the play "Pygmalion", the basis for the musical My Fair Lady (1964). Mrs. Campbell was legendary for her inappropriate remarks, and she failed dismally in an attempt at a Hollywood film career.
The play opened on Broadway in New York City, New York, USA on 22 October 1932 and closed in May 1933 after 232 performances. The opening night cast included Constance Collier as Carlotta Vance, Paul Harvey as Dan Packard, Conway Tearle as Larry Renault and Cesar Romero as Ricci (character deleted from the movie). The play had 2 Broadway revivals, the last in 2003.
