Apple TV+ spy thriller Slow Horses
returns for its sixth season on September 16, bringing a darker chase-thriller tone, more character deaths, and the adaptation of two Mick Herron novels, Joe Country and Slough House, as the disgraced MI5 agents go on the run from sinister forces.
Slough House Agents Hunted on the Run in Season 6
The critically acclaimed espionage drama Slow Horses is returning to Apple TV+ with its sixth installment, premiering on September 16, with weekly episodes running through October 21. Unlike previous outings, the upcoming season breaks new ground by combining two of Mick Herron’s novels into a single narrative arc: Joe Country and Slough House, the sixth and seventh books in the spy series.
Director Adam Randall, who also directed season 4, revealed in an exclusive interview that the new episodes will trade some of the workplace humor found in earlier runs for a heavier, more perilous atmosphere. It’s still everything you hope for from Slow Horses,
Randall explained to Radio Times, adding that it’s definitely a darker season. It’s a heavier season. There’s a lot more threats, and there’s a lot more death — not to give anything away.
The plot kicks into gear after Diana Taverner embroils the cast of washed-up spies in a fatally high-stakes game of retaliation and revenge. The official trailer opens with the slovenly but brilliant spymaster Jackson Lamb, played by Sir Gary Oldman, standing in a garden and demanding of Diana Taverner, Do you know anything about why my Slow Horses keep turning up dead?
As Katherine Standish notes in the footage, anyone who has ever worked at Slough House is being targeted, prompting Lamb to describe the situation as a blood bath.
Kicked Out of Slough House Into the British Urban Wilderness
For the first time, the outcast agents find themselves forced entirely outside their familiar administrative basement. Director Adam Randall noted that the creative team decided early on to kick them out of Slough House
so the characters could be hunted across unfamiliar terrain. Randall modeled the chase sequences after the gritty aesthetic of British roadside culture, stating he always wanted to make a film in the kind of British urban wilderness of bowling alleys and service stations — kind of s**t England.
That shift in geography leaves every major character on the precipice of something dreadful,
dealing with personal demons and fractured arcs while evading lethal pursuers. Alongside Chung, the returning ensemble includes Jack Lowden as River Cartwright, Kristin Scott Thomas as Diana Taverner, Saskia Reeves as Catherine Standish, Aimee-Ffion Edwards as Shirley Dander, Rosalind Eleazar as Louisa Guy, Ruth Bradley as Emma Flyte, James Callis as Claude Whelan, Tom Brooke as J.K. Coe, Hugo Weaving as Frank Harkness, Joanna Scanlan as Moira Tergorian, and Jonathan Pryce as David Cartwright.
The upcoming episodes also mark the highly anticipated return of Olivia Cooke as Sid Baker, a character who hasn’t been seen since Season 1 back in 2022. Teasing her reappearance in the trailer, Lamb remarks to Standish, Oh come on we’re spies, we’ve all faked our own death at one time or another,
right before Cooke’s character comes face to face with River Cartwright.
Gary Oldman on Jackson Lamb and Welcoming Newcomer Lenny Rush
While the character of Jackson Lamb is defined by his foul mouth, pungent wardrobe, and zero-tolerance filter, Sir Gary Oldman was quick to emphasize during a virtual press conference in Edinburgh that he shares very few traits with his Emmy Award-nominated alter ego. Well, I would hope not,
Oldman responded when asked if he had picked up any of Lamb’s bad habits, pointing out that he does not smoke, has quit drinking, and actively avoids the kind of confrontation that Lamb relishes. Addressing rumors regarding his on-screen aroma, the veteran actor joked, I haven’t farted since 1971,
adding that his unwashed appearance is entirely the product of makeup, hair gel, and smoke and mirrors.
Season 6 also introduces a mysterious new addition to the call sheet: BAFTA-winning young actor Lenny Rush. Known primarily for his breakout comedic work in Am I Being Unreasonable?, the 17-year-old actor was spotted filming scenes alongside Oldman and Christopher Chung. Chung praised the newcomer, noting that it is really great
to see Rush transition from comedy into the dark, espionage-driven world of the Apple TV+ hit. With production already wrapped and season 7 expected to begin shooting in September/October, the spy drama maintains its remarkably swift annual release cadence as it hurtles into its most lethal chapter yet.
