Billy Long Sr, a former undefeated professional boxer, had to end his boxing career after three years due to financial and mental health issues. However, he significantly impacted the lives of many young people through his mentoring efforts, which later became the inspiration for a successful British filmmaker.
When Billy Long Jr, his son, was dealing with autism, attention deficit hyperactivity disorder (ADHD), and bullying from local gang members, Long Sr took matters into his own hands. Concerned for his son’s safety and well-being, he chose to homeschool him and set up a makeshift boxing gym in a garden shed located in a council estate in Chelmsford, Essex.
Despite its modest size, comparable to a portable building, this space became a training ground for his son. Over three years, Long Sr watched his son’s transformation from a novice to a junior national boxing champion. Eventually, Billy Jr was selected to represent England and triumphed at the European Junior Boxing Championships in Bosnia in 2024, winning his matches without losing a single round—a remarkable feat.
Long Sr’s greatest pride comes from proving that his son’s autism, often seen as a drawback, was actually his “superpower” in the ring.
The success of Long Jr and the effective coaching by Long Sr began to attract local youths, steering them away from potential paths toward juvenile delinquency, drugs, and knife-related crimes. Long Sr expanded his efforts by opening Longs ABC, a boxing club with three rings located on a small industrial estate. The club has become a breeding ground for champions, producing four national champions, including two females.
Currently, both Long Sr and his 15-year-old son are collaborating with Nick Moorcroft, known for his film “Urban Hymn,” which featured Letitia Wright in a standout role. The idea of their life story being portrayed on film feels surreal to Long Sr.
Moorcroft, drawn to their powerful narrative of overcoming adversity, sees Long Jr as “one of the most gifted athletes in the world,” with his autism contributing to his intense focus and dedication in the sport.
Interestingly, Long Sr initially didn’t see a natural talent for boxing in his son. Along with his wife, Samantha, they disregarded skeptics who doubted their son’s capabilities due to his mental and physical challenges. Long Sr always believed his son had the makings of a champion, often pushing past perceived limits where others might give up.
Long Jr himself credits boxing with keeping him on track, providing him with a sense of control that he struggles to find outside the ring.
Long Sr, now 36, is all too familiar with the struggles of disadvantaged youth, having been written off by his own teachers and falling into bad company during his younger years. His father’s intervention, introducing him to boxing, not only gave him a new direction but also a professional career.
Abandoning his professional aspirations in 2016 to focus on his son, Long Sr has seen his child gain respect and avoid trouble, contrasting sharply with his own turbulent youth. He also coaches his other sons, Mason and Harry, who are making their own marks in sports and coaching, respectively.
The upcoming film, titled “Long Shot,” will not only focus on boxing but also the broader theme of overcoming adversity. It will feature children from various boxing clubs and include cameo appearances by Long Sr and Jr.
Moorcroft, who has a personal connection to the story, having experienced a troubled youth himself in Chelmsford, aims to highlight the importance of government support for amateur boxing through this project. He stresses that gyms like Longs ABC play crucial roles in their communities by providing discipline, mentorship, and a positive outlet for young people.
Long Sr emphasizes the inclusive nature of his gym, which brings together individuals from diverse backgrounds, fostering a sense of community and unity through the sport of boxing.
As Moorcroft prepares the script for “Long Shot,” he is also wrapping up his latest directorial project, a comedy-drama titled “Mother’s Pride,” set to release next spring, focusing on the British pub scene and the Great British Beer awards.
