Apple TV+ has renewed its darkly comic, London-set spy drama Slow Horses for a fifth series, with Gary Oldman returning as Jackson Lamb.

Lamb heads up the eponymous dumping-ground department, where a bunch of dysfunctional intelligence agents known as ‘slow horses’ – who have botched their careers but not quite been fired – are sent to work. The series is based on Mick Herron’s books.

Apple’s logline for Series 5 reads: “Everyone is suspicious when resident tech nerd Roddy Ho has a glamorous new girlfriend, but when a series of increasingly bizarre events occur across the city, it falls to the Slow Horses to work out how everything is connected. After all, Lamb knows that in the world of espionage, “London Rules” should always apply.”

The series is produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith. Will Smith, Jamie Laurenson, Hakan Kousetta, Iain Canning, Emile Sherman, Douglas Urbanski, Gail Mutrux, Julian Stevens and Graham Yost serve as executive producers on the series. The director for season five has not yet been announced.

The ensemble cast includes Kristin Scott Thomas, Jack Lowden, Saskia Reeves, Rosalind Eleazar, Christopher Chung, Samuel West, Sophie Okonedo, Aimee-Ffion Edwards, Kadiff Kirwan and Jonathan Pryce.
