Slow Horses Season 5 Confirmed: Release Date, Cast News, and Plot Teasers for Apple TV+ Spy Thriller
Slow Horses Season 5 & 6 Confirmed by Apple TV+

In a move that will delight fans of intelligent espionage drama, Apple TV+ has officially greenlit not one but two new seasons of its critically acclaimed series Slow Horses. The streaming giant confirmed that seasons 5 and 6 are officially in the pipeline, ensuring the future of the misfit MI5 agents from Slough House.

Double Renewal: A Vote of Confidence

This double-season renewal is a significant vote of confidence in the series, which has become one of Apple TV+'s standout original productions. Based on Mick Herron's bestselling Slough House novels, the show has consistently delivered a perfect blend of gritty spy thriller and sharp, character-driven humour.

What We Know About Season 5

While an exact release date for Season 5 remains under wraps, production is expected to commence shortly. The new season will likely adapt Herron's fifth novel, London Rules, which plunges Jackson Lamb and his team into a complex web of terror threats and political machinations.

The core cast is set to return, including:

  • Gary Oldman as the brilliantly offensive and unkempt spymaster Jackson Lamb
  • Jack Lowden as the disgraced but talented River Cartwright
  • Kristin Scott Thomas as the icy MI5 second desk, Diana Taverner

Why Slow Horses Continues to Captivate

The series' success lies in its unique tone. It masterfully subverts the polished glamour of traditional spy franchises like James Bond, instead offering a grubby, bureaucratic, and darkly funny look at the intelligence world. Gary Oldman's transformative performance as Jackson Lamb, a character who is both grotesque and genius, has been universally praised.

With a loyal and growing fanbase and a rich source material from Herron's ongoing book series, the future looks bright for the Slow Horses. The two-season order guarantees that viewers have plenty more mishaps, conspiracies, and unexpected heroism to look forward to from the most incompetent—yet oddly effective—team in British intelligence.
