The Jazz Singer (1927)
[opening lines, first quote and first words in the first widely-seen talking picture]
Jack Robin: Wait a minute, wait a minute, you ain't heard nothin' yet! Wait a minute, I tell ya! You ain't heard nothin'! You wanna hear "Toot, Toot, Tootsie"? All right, hold on, hold on...
[then he walks back to one of the band members]
Jack Robin: Lou, listen. Play "Toot, Toot, Tootsie", three chorus, you understand. In the third chorus, I whistle. Now give it to 'em hard and heavy, go right ahead.
Mary Dale: [Listening to Jakie cantoring at Yom Kippur services after the death of his father] A jazz singer...singing to his God!
Jack Robin: [sings] I'll walk a million miles for one of your smiles, my Mammy.
Jack Robin: We in the show business have our religion too - on every day, the show must go on!
[title/caption appearing after Yudelson and Jakie's mother first sees him in blackface]
Moisha Yudelson: He sounds like Jakie, but he looks like his shadow!
