Sydney has long been outspoken about her background in combat sports. She told Deadline in May: “I grappled and did kickboxing from 12-19 years old.

“I’ve been itching to get back into the ring, train, and transform my body.

“Christy’s story isn’t a light one, it’s physically and emotionally demanding, there’s a lot of weight to carry. But I love challenging myself.”

She added: “Christy Martin not only legitimized female boxing, she overcame gender stereotypes, and fought through emotional, physical, and financial abuse.

“I’m passionate about the fighting world, Christy’s story shines a light on her incredible rise to the top while showing the struggles of fame behind the curtains.

“I feel compelled to tell a story about a woman who faced so much adversity and didn’t allow it to defeat her. It’s powerful and emotional.”

Christy is an American former professional boxer. Competing from 1989 to 2012, she held the WBC female super welterweight title in 2009.

The athlete was the first female boxer elected to the Nevada Boxing Hall of Fame in 2016 and was then elected to the International Boxing Hall of Fame in 2020, which was the first year that women were on the ballot.

The boxer’s life was marked by a near-fatal turn on November 23, 2010, when her husband, James V. Martin, viciously stabbed and shot her in their Apopka, Orange County, USA, home, leaving her for dead.

Despite the brutal attack, Christy survived, and James was arrested a week later after attempting to take his own life.

In 2012, he was convicted of attempted second-degree murder and sentenced to 25 years in prison.

Now remarried to her former boxing rival Lisa Holewyne, Christy leads Christy Martin Promotions, a successful company that organizes boxing events across the southern US.

“The film is about Christy as a young gay woman in small-town West Virginia in the 1990s,” David Michôd explained.

He further told Deadline: “She came from a relatively conservative family and wasn’t allowed to be who she was so she used boxing as a vehicle to express herself and her rage.

“She had to make some dangerous and fundamental compromises in her life, the most important of which was marrying an incredibly dangerous man.”
