Analysis
What Apple announced
Apple TV+ says the sixth season of Slow Horses will premiere on September 16, with new episodes arriving weekly until October 21. The company also shared a first-look image featuring Gary Oldman as Jackson Lamb, the blunt MI5 leader at the center of the series.
Why the show matters to Apple
The article frames Slow Horses as one of Apple’s bigger hits and a major success for its British drama effort. It has already won multiple Emmy and BAFTA TV awards, and all five existing seasons are described as certified fresh on Rotten Tomatoes.
What changes in season 6
The story notes a key behind-the-scenes shift: Will Smith, who served as showrunner for the first five seasons, is no longer involved. Gaby Chiappe, known for creating The Beast Must Die, is now the lead showrunner. That makes the next season notable not just for its release date, but for how the tone and execution may evolve.
Plot setup
Apple says season 6 will put Diana Taverner into a chaotic position, with Slough House caught in a cycle of retaliation and revenge. The article does not go deeper into plot details, but it makes clear the season will continue the series’ darkly comic spy-drama setup.
Bigger picture
The article also says the show is already renewed for season 7, and an eighth season is believed to be in production. That suggests Apple still sees the series as a long-running asset for Apple TV+, not just a one-off success.
Key points
- Apple TV+ says Slow Horses season 6 premieres on September 16.
- New episodes will release weekly through October 21.
- Gary Oldman returns as Jackson Lamb in the first-look image.
- Will Smith is no longer the showrunner; Gaby Chiappe is leading season 6.
- Apple says the new season centers on Diana Taverner and a revenge-driven conflict.
If the new season lands well, Apple keeps one of its most reliable Apple TV+ originals strong for another year. The already announced season 7 and reported season 8 production suggest the series could remain a long-running anchor for the service.
The showrunner change could affect the tone that helped make the first five seasons work. If the new season does not match past quality, Apple risks weakening one of its best-regarded originals.
