There are numerous historical inaccuracies, and should not be considered a true rendering of Eagels's life and career.
When Jeanne is riding down Broadway and passes the show marquee, Fanny Brice's name is misspelled 'Fannie'.
The song that Jeanne (Kim Novak) sings in her "last movie" "Forever Young", "I'll Take Romance" was written in 1937, eight years after Eagels death. The song appears in the 1937 film with the same name.
During a carnival scene at Coney Island, the music in the background is The
Victory Polka which was written by Jule Styne and Sammy Cahn during World War II and not yet written for a film set in the Roaring Twenties.
