Slow Horses Season 6 Cast

Gary Oldman leads the ensemble cast as Jackson Lamb, the irascible spymaster who oversees the team of disgraced MI5 operatives at Slough House. The core cast from previous seasons is expected to return for the upcoming installment, maintaining continuity that viewers have come to expect from the series.

• Jack Lowden as Marcus Longridge
• Olivia Cooke as Sidonie “Sid” Bell
• Jonathan Pryce as Jed Moody

Kristin Scott Thomas portrays Diana Taverner, whose elevation to First Desk will significantly impact the dynamics at Slough House in Season 6. The power shift stemming from her promotion drives much of the narrative tension in the adaptation of Herron’s novels.

Production wrapped on the season ahead of schedule, with work already proceeding on Season 7. This ahead-of-schedule production suggests Apple TV+ remains committed to maintaining consistent release windows for the franchise.

Slow Horses Season 6 Trailer

As of early 2026, Apple TV+ has not released an official trailer for Season 6. The promotional campaign is expected to begin after Season 5 concludes its broadcast run, with marketing materials likely arriving in late spring or early summer 2026.

The official Apple TV+ description for the season reveals the central premise: “the Slow Horses on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge.” This synopsis indicates a marked escalation in stakes compared to previous seasons.

Marketing Expectations

• Full trailer likely in May or June 2026
• Teaser clips may appear on Apple’s social channels
• International trailer releases typically follow US debut
• Cast interviews and press materials expected in summer 2026

Slow Horses Season 7 Release Date

Apple TV+ confirmed the series has been renewed through Season 7, ensuring at least two additional installments beyond the upcoming season. Production on Season 7 is already underway, with the series maintaining a production schedule that allows for consistent annual releases.

Mick Herron’s Slough House series provides source material for the extended run, with multiple books remaining unadapted. Industry analysts note this positions the streaming platform to continue the franchise well into 2027 or beyond, depending on actor availability and creative decisions.

The decision to renew through Season 7 reflects Apple TV+’s confidence in the show’s performance metrics, which have consistently placed Slow Horses among the platform’s most-watched original dramas. This renewal also secures Gary Oldman’s involvement for the foreseeable future.
