EXCLUSIVE: Get a Closer Look at Brendan Gleeson and Harry Treadaway on 'Mr. Mercedes'

Ahead of AT&T's adaptation of Stephen King's 'Mr. Mercedes,' get a closer look at the crime series' central players.

Ahead of AT&T Audience Network’s anticipated adaptation
of Mr. Mercedes, ET has a closer look
at the crime series’ central players: Detective Bill Hodges (Brendan Gleeson)
and Brady Hartsfield (Penny Dreadful’s
Harry Treadaway).

On the upcoming series, which premieres Aug. 9, Gleeson
plays a retired detective haunted by the gruesome killing of 16 people -- a crime
that remains unsolved. “Every cop gets one they can’t shake. This is mine,”
Hodges says, referring to the “Mercedes Killer.”

That killer is Hartsfield, a demented psychopath who taunts
Hodges with a series of lurid letters and emails, forcing the former detective
out of retirement. “You don’t need to worry, Ma. I’m taking care of us in that
basement,” Hartsfield says to his mother (played by Kelly Lynch) about a secret
plan he’s working on.

Hodges and Hartsfield soon end up in a dangerous game of cat
and mouse as the retired detective tries to stop the killer before he strikes
