Less than a month after the series wrapped up its sophomore season, AT&T Audience Network has given a season 3 renewal to their critically acclaimed Stephen King adaptation Mr. Mercedes. Production on the 10-episode third season is set to begin early 2019, with the series set to return later in the year. David E. Kelley (Big Little Lies, Ally McBeal) is expected to return to oversee the writer's room, with Jack Bender (Lost, Under the Dome) directing. King, Kelley, and Bender will executive produce alongside Temple Hill Entertainment's Marty Bowen and Wyck Godfrey, Sonar Entertainment's Tom Lesinski and Jenna Santoianni, and AT&T Audience Network's Shane Elrod and Kate Regan.
Based on Stephen King's Bill Hodges trilogy (Mr. Mercedes, Finders Keepers, and End of Watch), the series focuses on a demented serial killer who taunts a retired police detective through a series of disturbing letters and emails. Knowing he's the only one who can stop the killer, the ex-cop undertakes a personal and deadly mission to stop his murderous reign before he claims another victim.
