Taron Egerton as Jimmy Keene

Jimmy was a star football player at Kankakee Eastridge High School, with plenty of friends and a promising future ahead of him. Unfortunately, it wasn’t enough for him to get picked up by a major college, and the once-promising football star became a prolific drug dealer instead. In 1996, Keene was arrested on drug charges and sentenced to ten years to life. The son of a decorated police chief, Jimmy tried to find a way out of his long sentence. Keene was given two options: either stay in the minimum security prison and do his allotted time or be transferred to a maximum-security prison for the criminally insane to go undercover for the FBI. Once in the dilapidated prison, Keene is instructed to elicit a confession from suspected serial killer Larry Hall, and help them find the location of his victims' bodies. If Keene can get the information they need to convict Hall, he’ll be granted his freedom. Keene, eager to shorten his long sentence, took the job, though nothing could prepare him for what he had to endure.

Taron Egerton will be taking on the role of the mob-corrupted man who must earn his freedom from behind bars. Egerton is known for his role as Eggsy in the Kingsman film franchise, as well as taking on the starring biopic roles of Elton John in Rocketman and Eddie Edwards in Eddie the Eagle. In 2018, the Kingsman star won the CinemaCon award for Action Star of the Year. His fight choreography and experience in action roles will likely come into play as he takes on the character of Keene, who encountered violence from his fellow inmates while behind bars.

Paul Walter Hauser as Larry Hall

Larry Hall is suspected of killing 40 women, though, in Black Bird, investigators have only found the body of one thus far. Hall insists that he’s not a killer, but that he has dreams in which he kills women. Though the suspected murderer insists that they are just dreams, the investigators fear that if he isn’t convicted of his crimes, he will leave prison and continue to kill. Hall, a war reenactment fanatic, had a long history of stalking young girls, often teenagers, in his tan van, where police found ropes, knives, chemicals, and masks prior to his arrest.

Paul Walter Hauser is an accomplished actor who has taken on diverse roles in both television and film. He is recognizable as his character Horace in the 2021 Disney film Cruella, in which he portrays the oafish criminal sidekick of the fashionable antihero. Though often portraying characters he himself considers doofuses in comedies, such as Super Troopers 2 and Reno 911!, Hauser is no novice when it comes to serious roles. In 2017, Hauser portrayed Shawn Eckhardt in the drama film I, Tonya. As the ice skater's bodyguard, Hauser perfectly emulated his real-life counterpart, who played a large role in the attack on figure skater Nancy Kerrigan. Hauser has stated that he was wary of taking on the role of Larry Hall, finding himself growing more uncomfortable with true crime as he ages. Though, the BlacKkKlansman actor feels that the Black Bird story is more about the relationship between Hall and Keene, rather than being a gross-out gory horror series. Hauser currently has two more upcoming projects in post-production, Delia’s Gone and National Anthem, both said to be violent thrillers. Hauser underwent quite the transformation to take on the role of Larry Hall, including losing 40lbs and changing the pitch of his voice to be much higher. Additionally, the Cobra Kai actor utilized prosthetics to give him Hall’s distinctive muttonchop sideburns.
