A documentary about a city man’s foray into the world of mixed-martial arts, amid the backdrop of a deadly disease suffered by his twin sons, will be shown Friday at a premiere event at the Shaw’s Center.

Mark Chaupetta, 40, said he went against the advice of doctors when he took part in a cage fight at Campanelli Stadium last August, which he won. The event raised money for battling Duchenne muscular dystrophy, from which his twin 14-year-old sons, Troy and Andrew, suffer.

Chaupetta’s training and fight are the subject of the 80-minute documentary, “A Father’s Fight.”

“I’m psyched. The movie’s awesome,” said Chaupetta, a professional private investigator. “I think it gives a positive thumbs up to the City of Champions here, sheds some positive light on the city.”

The movie was filmed between April and August of last year, and is directed by Ron Van Dam, a talk show host on WXBR-1460 AM and owner of Televisuals Productions.

The movie documents Chaupetta’s rigorous training process, which included a trip to Las Vegas to train with Forest Griffin, who competes in the Ultimate Fighting Championship.

It also shows people’s skepticism about a 40-year-old taking part in mixed-martial arts, typically considered a young man’s game, Chaupetta said.

“In the film we show the twins’ neurologist telling me not to do it,” he said. “A lot of family and friends would’ve rather I did a golf tournament than fight in a cage.”

Chaupetta said he has fielded interest in the film from a Los Angeles distribution company and been asked about putting the movie on pay-per-view, though no deals have been finalized.

Friday’s premiere event begins at 7:30 p.m. at the Shaw’s Center, 1 Lexington St. in Brockton. Admission is $30 per person and tickets are limited.

The screening starts at 8:15 p.m., and will be followed by a performance by the female pop duo Carmen & Camille, who contributed the soundtrack to the film, Van Dam said.

Chaupetta said that after production costs are met, proceeds will go toward research for Duchenne muscular dystrophy.
