The Jazz Singer was NOT the first full-length film to feature sound OR spoken dialogue.

Though The Jazz Singer was a groundbreaking film, classifying it as the first sound film, "talkie," or movie musical are all commonly held misconceptions. These honors all belong to the less well-known John Barrymore silent film, Don Juan. Although The Jazz Singer was not the original "talkie," it does hold the distinction of being the first film to feature spoken dialogue as part of the dramatic action. Only about a quarter of the picture features speaking, however. The first full-length film to feature dialogue throughout was Warner Bros.' 1928 gangster flick, Lights of New York.
