Apple TV+ Confirms Production of Slow Horses Seasons 6 and 7! Here's What to Expect

Liputan6.com, Jakarta Apple TV+ has officially confirmed the renewal of the popular spy series "Slow Horses" for a sixth and seventh season, after the airing of the fourth season finale.

Production for Slow Horses Season 6 wrapped in February 2025, marking significant progress in the series' development.

Meanwhile, filming for the seventh season is scheduled to begin in October 2025.

This renewal ensures the continuity of the story, adapted from the acclaimed "Slough House" book series.

With Gary Oldman reprising his iconic role as Jackson Lamb, the new season is expected to deliver a more complex and suspenseful storyline.

The series continues to be produced by See-Saw Films, renowned for its faithful translation of the dark and humorous spy novels to the screen.

Apple TV+ has officially announced the renewal of "Slow Horses" for a sixth and seventh season.

“Slow Horses has won fans all over the world with its unique mix of self-deprecating British humor and high-octane action," said Apple TV's Jay Hunt in a press release.

"I’m delighted viewers will have another season to enjoy Gary’s magnificent performance as Jackson Lamb alongside the Slow Horses’ slightly inept spycraft."

Furthermore, in July 2025, Apple TV+ announced a renewal for a seventh season, confirming the continuation of the adaptation of Mick Herron's novels.

Meanwhile, filming for the seventh season is scheduled to begin in October 2025.

See-Saw Films, the production company behind the series' success, continues to be responsible for the adaptation.

This consistency in production is expected to maintain the quality of the storytelling and acting that have become the hallmark of "Slow Horses."

While an official release date for Slow Horses Season 6 has not yet been announced, fans can expect it to premiere in the fall or winter of 2026 on Apple TV+.

Apple TV+'s annual release schedule, coupled with the completion of filming for the sixth season, reinforces this prediction.

The sixth season will adapt two books from Mick Herron's "Slough House" series: "Joe Country" (2019) and "Slough House" (2021).

They will be involved in a "high-stakes game of revenge and retribution" orchestrated by Diana Taverner (Kristin Scott Thomas).

This story development stems from the end of the fifth season, where Diana Taverner successfully took over the First Desk position at MI5.

Meanwhile, the seventh season is planned to adapt the novel "Bad Actors," in which Jackson Lamb and his team will hunt down a spy at the heart of the British government.

The main cast of "Slow Horses" is expected to return for Slow Horses Season 6.

Gary Oldman will return as Jackson Lamb, joined by Kristin Scott Thomas as Diana Taverner, and Jack Lowden as River Cartwright.

Other key cast members such as Saskia Reeves, Rosalind Eleazar, and Christopher Chung will also return.

Furthermore, Hugo Weaving will reprise his role as Frank Harkness, adding depth to the cast.

The season will also introduce new characters played by talented actors such as Harry Lloyd from "Game of Thrones" and Lenny Rush from "Am I Being Unreasonable?".

Will Smith, the previous writer and executive producer, will not return after the fifth season.

Gaby Chiappe will take over as head writer for Slow Horses Season 6, while Ben Vanstone will lead the writing for the seventh season.

In keeping with the pattern of previous seasons, Slow Horses Season 6 is expected to have six episodes.

For fans looking to catch up or recap the adventures of the Slough House agents, all past seasons of "Slow Horses" are available exclusively on Apple TV+.

New episodes of Slow Horses Season 6 will also stream exclusively on Apple TV+, ensuring that subscribers will be the first to see the continuation of this thrilling story.
