The Jazz Singer
Now The Jazz Singer is considered as one the greatest films of all time. In its own right, it was revolutionary. I mean, it was the first feature-length talkie! Al Jolson, the main character, created his famous line on the spot, “Wait a minute, wait a minute, you ain’t heard nothin’ yet!”
The Terminator
Up next is the James Cameron film, The Terminator. And guys, Cameron actually allowed a completely unscripted moment to make it into the film. And that was a smart choice as the line became one of the most quoted movie lines. Once Arnold Schwarzenegger isn’t allowed into the police station, the script says he should leave in disappointment. However, Schwarzenegger had a different idea and just said, “I’ll be back.” Cameron loved the line so much that he made this originally “minor character” a major one in the film and its sequels.
