Speaking on the Inspire Me! podcast (via World of Reel), Stallone revealed that his script is a working progress, adding that “I wrote a few pages of it and it just seems to write itself.”

The actor and filmmaker than said that his prequel would catch up with Robert ‘Rocky’ Balboa while he’s still a teenager. Stallone suggested we’d see “Adrian at 15, Rocky at 17, Paulie, moving to a new neighbourhood, Rocky’s a bad boy.”

The veteran action star also said his prequel was “almost like Lady And The Tramp but with real people” – a reference to the 1955 animated Disney film about the romantic relationship between two dogs.

A quick scan of the Internet tells us that Balboa was born in Philadelphia in June 1945, which means Stallone’s prequel would take place in 1962. The story would then presumably explore how he got into boxing, and show some of the bouts he fought in before the events of 1976’s Rocky.
