Warner Bros.' and director Alan Crosland's The Jazz Singer (1927) is an historic milestone film and cinematic landmark. [Most people associate this film with the advent of sound pictures, although Don Juan (1926), a John Barrymore silent film, also had a synchronized musical score performed by the New York Philharmonic and sound effects using Vitaphone's system.] It should be made clear that this film was not the first sound film, nor the first 'talkie' film or the first movie musical.
