The Jazz Singer
Generally considered the first sound feature, this 1927 film is pretty much silent except for a few lines of dialogue and Al Jolson's songs. The story finds Jolson playing the son of a cantor who wants him to follow in his footsteps, but the singer prefers secular music. Except for its historical value, the film isn't all that interesting, though it is great to get a sense of why people considered Jolson to be a hugely exciting entertainer at the time.
