## How Chuck Wepner Inspired Sylvester Stallone to Write Rocky

Former heavyweight boxer Chuck Wepner inspired Sylvester Stallone to write the classic underdog story Rocky after going 15 rounds and knocking down Muhammad Ali in 1975. Ahead of the movie's 50th anniversary, a new film titled I Play Rocky details how the actor fought studio executives to secure the lead role, refusing offers up to $360,000 for the script.

Stallone had been struggling financially before penning the script, at one point selling his dog Butkus for $40 to buy food. Studio bosses wanted a household name like Burt Reynolds to play Rocky Balboa, but Stallone stood his ground and landed three Oscars following the film's release.

## Tough Beginnings and Similar Paths

Both men overcame difficult upbringings in New York, with Stallone suffering facial paralysis at birth and facing an abusive household while Chuck grew up in a converted coal shed in Bayonne, New Jersey. After serving in the Marines, Chuck began working as a bouncer before entering the boxing ring and eventually winning the New York Golden Gloves Novice Heavyweight Championship.

Chuck fought as a part-time athlete for 15 years while working a full-time job before securing his historic title clash against Ali at Richfield Coliseum in Ohio. He entered the bout as a 40-to-one underdog and managed to knock down the champion in the ninth round before losing by a technical knockout in the 15th round.

## The Premiere and Later Legal Dispute

Chuck attended the New York premiere of Rocky and expressed amazement at the enthusiastic crowd reaction inside the theater. Stallone later wrote a part for Chuck in Rocky II, though the former boxer felt uncomfortable faking punches on screen.

The friendship between the two men soured in 2003 when Chuck sued Stallone for a share of the earnings from the Rocky franchise, which has grossed $1.8billion at the global box office. The legal dispute was eventually settled out of court for an undisclosed sum, and the pair later reconciled while working on the 2016 biographical sports drama Chuck.
