"Whispering" (music and lyrics by John Schonberger, Richard Coburn and Vincent Rose), sung by Alice Faye, was deleted from the film.
Although a Twentieth Century-Fox picture, this is one of the few Hollywood-made films in which one studio (Fox) acknowledges and names the existence of another (Warner Bros.) and credits them with the introduction of talking pictures. Don Ameche is actually shown watching a scene from Warner's The Jazz Singer , probably the only instance in Holywood history where one studio shows another studio's work within a film. Another rarity is that the head of the studio (J. Edward Bromberg) is openly portrayed as being Jewish. In later years Bromberg was blacklisted and ended up committing suicide. Fans of W.C. Fields will recognize Russell Hicks, who plays the stone-hearted money-man Roberts in "Hollywood Calvacade," as fast-talking con man J. Frothingham Waterbury, who sold Fields shares in the Beefstake Mine in the classic comedy The Bank Dick.
Many film historians believe this movie was based off the real life story of Mack Sennett and Mabel Normand. Darryl F. Zanuck actually hired Mack Sennett to serve as a technical advisor for this film.
This was Alice Faye's first movie in Technicolor.
This was the first film which combined black-and-white and color film stocks.
