Jack Huston and Maximiliano Hernández have joined the cast of AT&T Audience Network’s “Mr. Mercedes.”

Huston and Hernández will both appear in Season 2 of the mystery thriller series. According to Deadline, Huston will play Brady Hartsfield’s (Harry Treadaway) doctor, Dr. Felix Babineau, while Hernández will portray Assistant DA Antonio Montez.

Huston is best known for his role as Pete Musane in 2013’s black comedy-crime film “American Hustle.” The English actor also played the titular role in 2016’s epic historical film “Ben-Hur” and starred as Richard Harrow on HBO’s period crime drama “Boardwalk Empire.”

Meanwhile, Hernández rose to prominence for playing Agent Jasper Sitwell in the Marvel Cinematic Universe. The 44-year-old actor also recurs as Doc Rios on TNT’s post-apocalyptic action drama “The Last Ship.”

In addition to Treadaway, Huston and Hernandez join other returning cast members Brendan Gleeson as Detective Bill Hodges, Jharrel Jerome as Jerome Robinson, Scott Lawrence as Detective Peter Dixon, Breeda Wool as Lou Linklatter, Justine Lupe as Holly Gibney, and Holland Taylor as Ida Silver.

Variety reported last October that David E. Kelley will return to write the script for the next season, with Jack Bender also returning as director. Kelley, Bender, and King will also continue to serve as executive producers, along with Dennis Lehane, who will also write.

Just like Season 1, Season 2 will be based on Stephen King’s Bill Hodges Trilogy, which includes “Mr. Mercedes,” “Finders Keepers,” and “End of Watch.” “The master plan, which of course is always subject to change, is each book would represent a whole season, and ‘Mr. Mercedes’ is the first season. Then we’ll turn to Season 2 and the second book,” Kelley told The Hollywood Reporter last August.

Although there are only three books in the novel series, Kelley said that he’s open to going beyond a potential third season. “Going into this, the idea is that we have three books and in success it would make for three seasons and then,” Kelley said. [But] who knows? Maybe longer if we’re having fun.”

Production for the 10-episode Season 2 will start in February in Charleston, South Carolina.
