The fifth season of Slow Horses will be based on Herron's Spook Street. Everyone is suspicious when techie Roddy Ho (Christopher Chung) has a glamorous new girlfriend, but when a series of increasingly bizarre events unfold in the city, it's up to the Slow Horses to figure out how everything connects.
The cast includes Oldman, who plays lead actor Jackson Lamb, Academy Award nominee Kristin Scott Thomas, Jonathan Pryce, Jack Lowden, Saskia Reeves, Rosalind Eleazar, Chung, Samuel West, Sophie Okonedo, Aimee-Ffion Edwards and Kadiff Kirwan .
The series was produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith (no, not that Will Smith). Smith, Jamie Laurenson, Hakan Kousetta, Iain Canning, Emile Sherman, Douglas Urbanski, Gail Mutrux, Julian Stevens and Graham Yost serve as executive producers of the series. The director for season five has not yet been announced.
