Real people played by accomplished actors is just the start of the remarkable “Unstoppable,” streaming on MGM Prime Video Thursday.

Anthony Robles, born without a right leg, became an Arizona State NCAA wrestling titan which he chronicled in his 2012 autobiography, “Unstoppable: From Underdog to Undefeated: How I Became a Champion.”

His story, highlighted by a life-long bond with his single mother Judy, is now a film produced by Ben Affleck, starring Jharrel Jerome (“Moonlight”) as Anthony, Jennifer Lopez as Judy and with Robles himself as Jerome’s wrestling stunt double.

“I could not be more proud of how my story was told,” Robles, 36, offered in a virtual press conference.

“It’s been pretty unbelievable, how well done it is,” Judy added.  “We’ve had this unbreakable bond since he was born — and to see us represented authentically!

“Jennifer,” she continued, “had questions for me and knew it was important to portray me as I am. Like the protectiveness that’s shown, everything about it. I was overwhelmed because I’ve seen this film seven or eight times now and I still cry. Nobody could have done better. I’m grateful she wanted to portray me.”

“A lot went into all the things Judy shared with me,” Lopez, 55, noted. “It’s not easy to put your life out in the public eye. I know that.

“But that was key: to tell me her story in the best way. It’s really the struggle she had as a mother and son, a wife, and just as a woman. To bring that all together and bring the full person you see here who is amazing and complicated, as any mother is.”

“We know him as a wrestler and a champion,” Jerome, 27, said. “But he is such a protector, such a kind soul. Almost the opposite of who he is on the mat, where he dominates.

“That’s a testament to his life and all the adversity he’s faced. Judy has been the strength of this. Jennifer and I knew that early on: To show the bond they had because there’s no Anthony Robles without Judy Robles.

“This was always a story about a mother and a son, an undying love and how they raised each other. That made it unique; many can relate. It’s a universal thing.”

Doubling Jerome was, “definitely a new experience for me,” Robles said.” It was easy to open up to him, trusting in him about certain painful memories I otherwise wouldn’t have talked about.”

Added Jerome, “We banged it out for seven months, five days a week, two hours on the mat. I learned knowing what you can do and knowing what your limit is – which is no limit at all.”
