Mr. Mercedes (Seasons 1–3)

Mr. Mercedes (2017) is a Stephen King crime thriller you can watch online on iFILM. The series ran for three seasons on Audience Network, starring Brendan Gleeson as a retired detective and Harry Treadaway as the killer he cannot stop thinking about.

Bill Hodges left the force with one open case: a man drove a stolen Mercedes into a crowd at a job fair and killed eight people. Brady Hartsfield got away. Now he's sending Hodges taunting letters — and planning something far larger, an attack that could kill hundreds. Hodges pulls together an unlikely team, none of them police, and begins a private hunt that is equal parts procedural and psychological standoff. Treadaway plays Hartsfield not as a cartoon villain but as someone who needs an audience more than anything else.

Three seasons stay clear of King's supernatural catalogue — this is the version of King where the horror is just a man, a plan, and no one who can stop him in time. Stream all seasons of Mr. Mercedes online on iFILM.
