A first-time screenwriter turned down escalating offers for his script, choosing copyright ownership (the legal right that lets a creator control who buys their work and on what terms) over a guaranteed payday. That screenwriter was Sylvester Stallone, and the script was "Rocky." Amazon's upcoming biographical drama "I Play Rocky," directed by Peter Farrelly and due in November, re-examines how that bet on himself transformed a broke unknown into a Hollywood legend.

What Stallone actually walked away from

The numbers were real. Producers Robert Chartoff and Irwin Winkler wanted to buy the "Rocky" script outright, and their offers climbed to $360,000 with established stars already circling the lead role. Ryan O'Neal, Burt Reynolds, and James Caan were among the names attached. Entertainment attorney Marc Simon of Fox Rothschild in New York told Fox News Digital that in today's terms, $360,000 is probably the equivalent of being offered over $2 million.

Stallone wrote the script in three days and was working as a valet attendant when he finished it. Tisha Morris, entertainment attorney at Legacy Arts Law, said most first-time writers would have been expected to take the money and relinquish casting control entirely. Stallone did the opposite. He owned the copyright, which gave him the legal right to simply refuse any sale he found unacceptable.

Film historian Dwight Cleveland said Stallone responded the way his character would: holding his ground because he believed the script was a winner and was unwilling to hand that shot at stardom to someone else.

The trade that made the math work for producers

Stallone's insistence on starring came with a concession. He accepted a sharply reduced salary and rights fee, which pulled the film's total budget down to roughly $1 million. United Artists, which had been cautious about an unknown actor carrying the picture, found that arrangement more manageable. Simon told Fox News Digital that the economics became more palatable to the studio precisely because Stallone's asking price for himself was low.

What the film earned, and who tells the story now

Released in 1976, "Rocky" received 10 Academy Award nominations. Stallone was nominated for both best actor and best original screenplay. The film won three Oscars: best picture, best director for John G. Avildsen, and best film editing.

"I Play Rocky" will retell this origin story, with Anthony Ippolito as Stallone and AnnaSophia Robb as Stallone's first wife, Sasha Czack. Stephan James, Matt Dillon, and P.J. Byrne are also in the cast. Stallone has publicly distanced himself from the project. He told The Playlist: "I was shocked to read [about] it. I have zero to do with it."
