Matt Hookings wrote this movie as well as playing the main character Jem Belcher. This mirrors Sylvester Stallone writing the movie rocky and playing the main character of Rocky Balboa.
When Belcher triumphed over Bartholomew in a seventeen-round rematch in 1800, he was hailed as the new champion. In 1803, Belcher lost sight in one eye when he was struck by the ball in a game of racquets. ... Perhaps Belcher should have retired to his pub, The Jolly Brewer, after the Pearce defeat. James 'Jem' Belcher was one of the most admired prizefighters of the Regency. He was renowned for his handsome looks, impeccable manners and eccentric boxing style which involved telling jokes to his opponents at the bloodiest moments of combat. He was defeated by the rising talent, Tom Cribb in 1807 and again in 1809, leading to his retirement soon after. His many victories inspired Egan's famous history of bare-knuckle fighting, Boxiana (1812). William Hazlitt, an ardent fan, fondly recalled him in his famous essay The Fight (1821).
