Most movie buffs know the first film with a partial soundtrack was “The Jazz Singer,” with superstar Al Jolson. But not too many can name the first movie with a full-length soundtrack, which opened on this date in New York in 1928. It was “The Lights of New York,” about the murder of a crime boss, a film which has faded into obscurity. After “The Jazz Singer” stunned the country, movie studios scrambled to change over from silent films to what were then called the “talkies.” It was a technical revolution that completely changed the making and viewing of movies, as you may have heard. In 1928, Americans went to the movies an average of about twice a week. Now, we average a little over four films a year in a theater.
