The third season of Mr. Mercedes will see Kate Mulgrew (Orange is the New Black), Brett Gelman (Stranger Things) and Natalie Paul (You) joining the Stephen King adaptation in recurring roles.
Mulgrew will play Alma Lane, a “life-long resident of Bridgton, Ohio and a compelling force in Morris’ life since he was a boy. She is a bit vicious and a lot smart.”
Gelman portrays Roland Finklestein, a “smart, passionate defense attorney who is representing Lou Linklatter in her murder trial. He believes he can win the case if they go to trial and keep Lou out of prison.”
Paul will play A. D. A. Sarah Pace, the prosecutor of Lou’s case. “At first glance one might think her soft, but she is a hardcore prosecutor with a strong moral compass. She doesn’t support or believe in Lou’s vigilantism and refuses to back down from pursuing justice.”
Season 2 will take place “a year after Brady Hartsfield’s (Harry Treadaway) thwarted attempt to perpetrate a second mass murder in the community of Bridgton, Ohio. Since the incident, Hartsfield had been hospitalized in a vegetative state. Retired Detective Bill Hodges (Brendan Gleeson) did his best to move on from his Brady obsession, teaming up with Holly Gibney (Justine Lupe) to open Finders Keepers, a private investigative agency. But when unexplainable occurrences began to affect hospital staff members attending to Brady, Hodges was haunted by the feeling that Brady was somehow responsible.”
David E. Kelly (Big Little Lies) will return as showrunner and writer with Jack Bender (Lost) directing the new season as well as Stephen King producing it. Production on the third season is taking place in Charleston, South Carolina.
