Russell Hornsby joins the cast of Mike Tyson biopic series Iron Mike to portray famed fight promoter Don King.

Variety reports that Hornsby joins Trevante Rhodes, who has been cast as Mike Tyson. King’s portrayal is described by the outlet as “ruthlessly ambitious with a flashy personality.” He is also described as being “a notorious boxing promoter that takes Tyson’s boxing career to the next level.”

“He’s a businessman; strategic, resilient, knowing how to work everything in his favor,” the outlet writes. “However, much of his arrogance might be hiding a deeper vulnerability. Wile others may focus on the little details, King has his eyes on the prize–always thinking of the bigger picture.”

The description lines up with some of what we know about King from his outward persona. The promoter, whose heyday occurred between the ’70s to the mid ’90s, is thought of as one of the best promoters in boxing and became a celebrity of his own, featuring on TV shows such as Miami Vice, Knight Rider, Frank’s Place and films like The Devil’s Advocate. He has also been a guest on many talk shows and sports documentaries over the years.

Iron Mike is currently in production at Hulu.

According to Iron Mike, the eight-part series “will explore the wild, tragic and controversial life and career of heavyweight champion Mike Tyson–one of the most polarizing figures in sports culture.” After facing repercussions from his violent actions during his boxing career, Tyson has had a career rebirth in the last decade or so with film roles in Rocky Balboa, Ip Man 3, and The Hangover movies, among others. He also voiced himself in the Adult Swim animated series Mike Tyson Mysteries.

Tyson has previously come out against Iron Mike and is executive producing a rival TV series about his life, Tyson, starring Jamie Foxx. He’s also executive producing TV series That Time I Met Mike, which is currently in pre-production.
