Apple TV has revealed the first images and release date of Slow Horses Season 6. As only major TV series can afford, Slow Horses had been confirmed for a sixth season when the season four finale had just come out, and Slow Horses Season 5 had already been confirmed almost a year earlier. Here is the first information on the next season of the fantastic English spy thriller series starring Sir Gary Oldman (the seventh season, meanwhile, has been confirmed in July 2025). Impeccable, elegant, and lethal secret agents have always dominated the world of espionage on television. However, the TV series Slow Horses, available on Apple TV, has completely overturned this myth, achieving extraordinary success with audiences and critics thanks to a completely original approach.
Slow Horses Season 6: Release Date for New Season of Cult Series Revealed?
The story does not chronicle the exploits of top field agents, but focuses on Slough House, a detached and downgraded branch of Britain’s MI5. This gray office is a veritable dumping ground for spies who have made unforgivable mistakes, failed crucial missions, or caused public embarrassment. Instead of being fired, these agents are confined, ironically nicknamed ‘nags,’ in the hope that they will quit due to the boredom of the bureaucratic tasks assigned to them. At the heart of this bizarre team is the quintessential antihero, Jackson Lamb, played by a monumental Gary Oldman. Lamb is a scruffy, crude, and seemingly uninterested man who spends his days insulting his subordinates. Behind this unpleasant facade, however, lies one of the brightest and sharpest minds in intelligence, a man who knows every secret of the trade.
“Slow Horses” is a darkly humorous spy drama and follows a team of British intelligence agents who serve in a department at the MI5 landfill, known in a way not as affectionate as Slough House. Gary Oldman plays Jackson Lamb, the brilliant and irascible leader of spies who end up at Slough House because of mistakes that have ended their careers, as they often find themselves wandering among the smoke and mirrors of the spy world. Season 6 sees the Slow Horses on the run as Diana Taverner involves them all in a game of retaliation and revenge, the stakes fatally high.
What Slow Horses Season 6 Will Be About?
Season six sees the Slow Horses on the run, while Diana Taverner drags them all into a game of high-stakes retaliation and revenge. Slow Horses is a darkly humorous spy drama that follows a team of British intelligence agents serving in a department at the MI5 landfill, known unaffectionately as Slough House. Gary Oldman as Jackson Lamb, the brilliant and irascible leader of spies who end up in Slough House because of career-ending mistakes, as they often find themselves wandering through the smoke and mirrors of the spy world.
The new season will kick off with the “nags” of Slough House on the run. Diana Taverner, played by Kristin Scott Thomas, will drag them into a dangerous game of retaliation and revenge. Put like that, it sounds like your average Secret Service intrigue, but Slow Horses has always had its merits: it takes spy stories and smears them with sarcasm, personal failures, sad offices, and agents who seem to have emerged from a bad workday.
At the center remains him, Jackson Lamb, the most grumpy, rude and brilliant boss imaginable. Gary Oldman plays him with a kind of ferocious enjoyment: unkempt hair, venomous jokes, tired walking, and that manly air that knows everything before anyone else, but prefers to make you understand it in the most unpleasant way possible. Lamb is the main reason why so many viewers were hooked on the series. He’s not the elegant James Bond hero. It’s the opposite. And that’s exactly why it works.
The sixth season will be based on Joe Country and Slough House, the sixth and seventh novels in Mick Herron’s literary series. This is an important choice, because the series will adapt two books in a single season. It means that the story could be denser, faster, perhaps even riskier. However, Slow Horses has already demonstrated its ability to handle plots full of double-crosses without losing its tone.
The Cast of Slow Horses Season 6?
The cast includes Oscar nominee Kristin Scott Thomas, Emmy 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, Oscar nominee Jonathan Pryce, and Hugo Weaving, as well as new addition Lenny Rush, winner of the BAFTA TV Award.
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 Gary Oldman serving as executive producers. The sixth season is adapted for television by co-executive producer Gaby Chiappe, with Adam Randall returning to direct.
When Slow Horses Season 6 Release Date?
The fifth season will consist of 6 episodes and will be released on Apple TV on Wednesday, September 16th, with the first episode, followed by one episode per week until October 21st.
The sixth season is directed by Adam Randall, who was already involved in the fourth season, while the television adaptation is by Gaby Chiappe. See-Saw Films and Apple TV are behind the production, with Gary Oldman also serving as an executive producer. In short, the project does not give the impression of a series dragged forward by inertia. In fact, it looks like a well-oiled machine, one that Apple has no intention of turning off.
And in fact, season seven is already in the works. That will adapt Bad Actors, the eighth book in Mick Herron’s saga. This means that Slow Horses isn’t just coming back for another spin: it’s building rare continuity for a contemporary series, especially at a time when many productions are canceled after two seasons, even when they have a loyal audience.
The success of Slow Horses, in my opinion, depends on one simple thing: it doesn’t try to look more elegant than it is. He tells spies, plots, and serious threats, but he does so with tired, irritating, wounded, and often ridiculous characters. People who have done something wrong and find themselves in an office considered a dumping ground for British intelligence. Then, punctually, those very failures end up in the midst of the most dangerous cases.
Season six will have to up the ante without betraying this identity. The more action goes well, the more tension there is too. But Slow Horses has to stay Slow Horses: dirty, sarcastic, intelligent, with Lamb always seeming on the verge of sending everyone to hell and then, somehow, saving the day.
