“That night,” Sly continues, “Rocky Balboa was born. He is a man of the streets. People looked on him as the all-American tragedy, a man without much mentality and few social graces. But he has deep emotion and spirituality and good patriotism. And he has a good nature, although nature has not been particularly good to him. I have always seen him as a 20th Century gladiator in a pair of sneakers. Like so many of us, he is out of sync with the times. To all this, I injected doses of my own personal life, of my frustration at not getting anywhere.”

They instantly sensed the magic in Stallone’s work, asked for a few rewrites and the negotiating began with a reported $75,000 offer.
