The Jazz Singer is a 1927 American part-talkie musical drama film directed by Alan Crosland and produced by Warner Bros. Pictures. It is the first feature-length motion picture with both synchronized recorded music and lip-synchronous singing and speech. Its release heralded the commercial ascendance of sound films and effectively marked the end of the silent film era with the Vitaphone sound-on-disc system, featuring 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".
