It was last summer that the the tragic passing of Anton Yelchin paused the series adaptation of Stephen King’s Mr. Mercedes, but the title killer is finally ready to ride. AT&T’s blood-soaked tale has a first full trailer for its August premiere.

Now set for a Wednesday, August 9 premiere, Mr. Mercedes released a first full trailer featuring Penny Dreadful star Harry Treadaway (replacing Yelchin) in the main role, along with stars Brendan Gleeson, Holland Taylor and Mary-Louise Parker. The David E. Kelley series will run for ten full hours, with a synopsis below:

“Mr. Mercedes” follows a demented killer Brady Hartsfield (Treadaway) who taunts a retired police detective Bill Hodges (Gleeson) with a series of lurid letters and emails, forcing the ex-cop to undertake a private, and potentially felonious, crusade to bring the killer to justice before he is able to strike again.

And a full cast:

Leading the “Mr. Mercedes” cast are Brendan Gleeson (“Harry Potter”) as Detective Bill Hodges, Harry Treadaway (“Penny Dreadful”) as Brady Hartsfield, Kelly Lynch (“Magic City”) as Deborah Hartsfield, Jharrel Jerome (“Moonlight”) as Jerome Robinson, Scott Lawrence (“Avatar”) as Detective Peter Dixon, Robert Stanton (“Mercury Rising”) as Anthony “Robi” Frobisher, Breeda Wool (“Unreal”) as Lou Linklatter, Justine Lupe (“Francis Ha”) as Holly Gibney, and Ann Cusack (“Nightcrawler”) as Olivia Trelawney, with Mary Louise-Parker (“Weeds”) as Janey Patterson, and Holland Taylor (“The Truman Show”) as Ida Silver.
