Jamie Foxx has assured fans that the long-awaited Mike Tyson biopic is definitely happening. 

It has been six years since it was announced that Jamie Foxx will play the former heavyweight champion boxer, so understandably, fans were beginning to wonder if the movie was going to happen to all. But Foxx has now confirmed that the project is finally moving forward. 

Speaking on Instagram Live with producer Mark Birnham, Foxx said: "It's a definitive yes. Doing biographies is a tough thing. Sometimes it takes 20 years to get them done, but we officially got the real ball rolling."

Foxx is no stranger to playing real-life figures, having won the best actor Academy Award for playing singer Ray Charles in the acclaimed 2004 biopic Ray.

He said he "can't wait" to show the different sides of 53-year-old Tyson, who was one of the most feared fighters in boxing history before his career petered out due to out-of-the-ring distractions.

Mike Tyson took part in a total of 58 fights in his professional career. Fifty of those he won, 44 of them being by knockout.

"We want to show everybody evolves," Foxx said. "I think when we lay the layer of Mike Tyson in this story, I think everybody from young and old will be able to understand this man's journey."

In preparation for the role, Foxx revealed his workout regime. 

"Every other day, I do 60 pull-ups, we do 60 dips, we do 100 push-ups. I ain't got no calf muscles, so we might have to get some prosthetics for that."

Foxx also told the story of how he first met Tyson, about 30 years ago.

He said: "I met Mike Tyson in the weirdest way, I was on stage doing stand-up years ago. I get to my Mike Tyson joke and nobody claps, nobody laughs. You know why? Because Mike Tyson was watching."
