The Jazz Singer is a 1927 American musical drama film directed by Alan Crosland. It is the first feature-length motion picture with both synchronized recorded music score as well as lip-synchronous singing and speech (in several isolated sequences). Its release heralded the commercial ascendance of sound films and effectively marked the end of the silent film era. It was produced by Warner Bros. with the Vitaphone sound-on-disc system and features six songs performed by Al Jolson. Based on the 1925 play of the same title by Samson Raphaelson, the plot was adapted from his short story "The Day of Atonement".
