According to the plot of this revolutionary 1927 film, an orthodox cantor wants his rebellious son to follow in his footsteps. Name the title, lead actor, and the significance of this film?

The 1927 film in question is the groundbreaking musical drama, The Jazz Singer. It starred Al Jolson, one of the most popular and dynamic entertainers of his era, in the lead role of Jakie Rabinowitz. The plot perfectly matches the description, centering on the intense conflict between Jakie's desire to become a popular jazz performer and his devout father's wish for him to continue the family's generations-long tradition as a synagogue cantor.

The film's monumental significance lies in its status as the first feature-length motion picture with synchronized dialogue, earning it the nickname "the first talkie." While other films had featured synchronized music and sound effects, The Jazz Singer was the first to have its characters speak and sing on screen. The mostly silent film was punctuated by several musical numbers and snippets of spoken dialogue from Jolson.

When audiences first heard Jolson ad-lib the line, "Wait a minute, wait a minute, you ain't heard nothin' yet!" it was a pivotal moment in cinematic history. The film was a massive box office success, and its popularity single-handedly convinced studios to abandon silent films and embrace the new era of sound, forever changing the course of the movie industry.
