Apple TV unveils first look at season six of Emmy and BAFTA Award-winning espionage drama "Slow Horses," starring Academy Award winner Sir Gary Oldman

Adapted from "Joe Country" and "Slough House," the sixth and seventh novels in Mick Herron's CWA Gold Dagger Award-winning "Slough House" book series, season six will debut globally on September 16, 2026

Today, Apple TV revealed a first look at season six of "Slow Horses," the Emmy Award and BAFTA TV Award-winning spy drama starring Academy Award winner Sir Gary Oldman, who has been honored with Golden Globe, Emmy Award, Actor Award and BAFTA TV Award nominations for his outstanding performance in the series. The highly anticipated six-episode sixth season will premiere globally on Wednesday, September 16, 2026 with the first episode, followed by one episode weekly until October 21, 2026.

"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 unaffectionately 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 and who frequently find themselves blundering around the smoke and mirrors of the espionage world.

Season six sees the Slow Horses on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge.

The ensemble cast includes Academy Award nominee Kristin Scott Thomas, Emmy Award nominee Jack Lowden, Saskia Reeves, BAFTA TV Award nominee Christopher Chung, Aimee-Ffion Edwards, Rosalind Eleazar, Joanna Scanlan, BAFTA Award nominee Samuel West, Ruth Bradley, Tom Brooke, Academy Award nominee Jonathan Pryce and Hugo Weaving, alongside new addition, BAFTA TV Award winner Lenny Rush.

"Slow Horses" has been celebrated as "undoubtedly the best spy series on television," a "truly epic espionage thriller" that is "utterly brilliant" and just "so damn good." All five seasons of "Slow Horses" hold a Certified Fresh score, with two seasons receiving a rare, perfect 100 percent critics' score on Rotten Tomatoes, and the series continues to receive global accolades from critics and fans alike.

The series is produced for Apple TV by See-Saw Films, with Jamie Laurenson, Hakan Kousetta, Julian Stevens, Iain Canning, Emile Sherman, Adam Randall, Gail Mutrux, Douglas Urbanski and Oldman serving as executive producers. Season six is adapted for television by co-executive producer Gaby Chiappe, with Randall returning to direct. The complete first five seasons of "Slow Horses" are now streaming on Apple TV.
