Sylvester Stallone was unsure about going back to his most famous role as boxer Rocky Balboa for a seventh film in the Rocky franchise despite being intrigued by director Ryan Coogler's plot for the movie.
He explained: "It took Coogler about two years to convince me. I had been very, very grateful the way last chapter of 'Rocky Balboa' wrapped up his story in a satisfactory way for the audience. When Rocky waves goodbye, that was a goodbye to the audience and a thank you. And then this fellow comes in, and says, 'Oh, can we dig him up?' I go, 'No, no, no, no.' Then he proceeded to tell me this story. My first reaction was it was disconcerting. It shows Rocky outside the ring, fighting the fight that he really can't win. It's a fight against the greatest opponent in the world; life. I said, 'No, kid, I think we're tampering with something here we should leave alone.' "
Stallone's agents and his wife Jennifer Flavin were desperate for him to make the movie - which stars Michael B. Jordan as 'Donnie' - to test himself on screen and depict Rocky in a way that audiences had never seen before.
And the 69-year-old action legend admired 29-year-old Coogler's commitment to the story and perseverance so much he decided to give him a chance to make his movie in the same way he was given an opportunity as a young man to make Rocky in 1976.
