Slow Horses action revealed in the Season 6 trailer

The espionage world just got a fresh dose of delightful dysfunction. Apple TV has reaffirmed its commitment to the brilliantly chaotic world of Slow Horses by greenlighting a seventh season, promising more high-stakes games, bitter retractions, and exquisitely dysfunctional British intelligence agents.

Season six is set to plunge the audience back into the smoky, paranoid atmosphere of Slough House, where a dysfunctional team of MI5 agents—punished for their career-ending mistakes—find refuge in a dumping ground department. At the heart of this chaotic existence is Jackson Lamb, brilliantly portrayed by Gary Oldman, the cantankerous leader who navigates the smoke and mirrors of the espionage world with an exasperated wit.

The narrative promise for this installment is pure, high-octane revenge. As the team starts to face mounting pressure, the plot escalates as Diana Taverner embroils them all in a fatally high-stakes game of retaliation, turning their internal strife into an external, deadly confrontation.

The series has already established itself as a darkly humorous espionage drama, expertly balancing the absurdity of their lives with the genuine danger they face. Now, with the new season approaching, the ensemble cast is ready to deliver another masterclass in character and tension. Kristin Scott Thomas, Jack Lowden, Saskia Reeves, and a formidable lineup including Christopher Chung, Aimee-Ffion Edwards, Rosalind Eleazar, Joanna Scanlan, Samuel West, and Tom Brooke are set to navigate these perilous waters alongside veteran actors like Jonathan Pryce and Hugo Weaving.

The story is further enriched by the return of Olivia Cooke as Sidonie “Sid” Baker, and the exciting addition of BAFTA TV Award winner Lenny Rush, who joins the crew for this new chapter.

The production remains anchored by the talent of 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. The season has been expertly adapted for television by co-executive producer Gaby Chiappe.

Fans can expect six thrilling episodes of this revenge-fueled saga to premiere on Apple TV starting on Wednesday, September 16.
