James Cagney turned down the lead role in The Jolson Story (1946), which went to Larry Parks.
Broadway? What a street! You know something, baby? It belongs to me. You know something else? If you want, I'll give it to you.
Immediately following Jolson's announcement that he'll star in The Jazz Singer, a view of New York is shown at night with an unmistakable Empire State Building seen in the distance with its unique lighting (although its appearance varies somewhat in the daytime view). The Jazz Singer debuted in 1927, but the Empire State Building only opened in 1931, with excavation only beginning in 1930, 3 years after The Jazz Singer debuted.
