It was initially reported sometime last year that Boston Public vet David E. Kelley is developing a limited event series based on Stephen King’s detective thriller Mr. Mercedes. The series now officially has a home with AT&T’s Audience Network, with Star Trek’s Anton Yelchin and Harry Potter’s Brendan Gleeson on board to play the lead roles.

It’s kind of a bummer for people who don’t subscribe to AT&T, but as THR reports, that’s exactly where Mr. Mercedes has landed with a straight-to-series order for a limited run of 10 episodes. Based on King’s 2014 novel of the same name, Mr. Mercedes centers on a widowed detective named Bill Hodges, who is pulled out of retirement when he receives a series of taunting messages from the maniac responsible for an unsolved mass murder.

Gleeson will play Hodges, with Yelchin in the role of Brady Hartsfield, the retail IT specialist and ice cream truck driver responsible for the mass killings. That’s some downright great casting — Gleeson is perfect for an older, retired detective and Yelchin is an often underrated presence who could really tear into a complex, dark role like this one.

Kelley will write the first episode of the series, serving as show runner and co-executive producer alongside LOST vet Jack Bender, who will also direct Mr. Mercedes. Bender previously worked with King on CBS’ adaptation of Under the Dome.

Mr. Mercedes is the first part of the Hodges trilogy, followed by 2015’s Finders Keepers and the upcoming End of Watch, which hit shelves on June 7. The AT&T series is eyeing a 2018 debut.
