Slow Horses S5 plays by London Rules

TRAILER: Gary Oldman returns to Slough House for season five of espionage drama Slow Horses, which is launching on Apple TV+ on September 24, 2025.

Slow Horses is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known affectionately as Slough House. Oldman stars as Jackson Lamb, the brilliant but cantankerous leader of the spies, who end up in Slough House due to their career-ending mistakes as they frequently find themselves blundering around the smoke and mirrors of the espionage world.

Adapted from London Rules, the next novel in Mick Herron’s Slough House book series, the six-episode season five opens with everyone suspicious that 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, the London Rules – cover your back – always apply.

The ensemble cast includes Kristin Scott Thomas, Jack Lowden, Saskia Reeves, Rosalind Eleazar, Christopher Chung, Aimee-Ffion Edwards, Ruth Bradley, James Callis, Tom Brooke and Jonathan Pryce. Season five will also features Nick Mohammed as a special guest star.

The series is produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith. Jamie Laurenson, Hakan Kousetta, Julian Stevens, Iain Canning, Emile Sherman, Douglas Urbanski, Gail Mutrux, Will Smith and Graham Yost are executive producers. Saul Metzstein returns to helm season five.

Seasons six and seven of Slow Horses have already been announced.
