Apple TV recently confirmed that they have greenlit an eighth season of Slow Horses right before the sixth season is set to premiere.

Just like the previous seasons, it will consist of six episodes. The eighth season will be based on Clown Town, the ninth novel in Mick Herron's Slough House book series. Gary Oldman and Jack Lowden are expected to reprise their respective roles once again.

The story sees Jackson Lamb and Diana Taverner face off in their most explosive confrontation yet. When a botched attempt to blackmail the Park puts Taverner on the offensive, it is up to Lamb to unravel one of MI5’s darkest secrets and put an end to it once and for all.

Jay Hunt, the international creative director at Apple TV, said in the statement: "Slow Horses continues to charm audiences all around the world, and I’m delighted that Jackson Lamb and his gang of lovable misfits will be back for an eighth season. Their acerbic take on the high-octane world of espionage is completely unique."

In case you're wondering, while the sixth season is set to premiere in a few days, the seventh season was already filmed last year, which is why Apple TV's recent move is to renew the show for an eighth season.

Unlike most streaming shows, Slow Horses manages to have an annual release of new seasons, and they usually film them in advance without any delay or waiting for viewership reports of the most recent season.

What to Expect in Slow Horses Season 6

The sixth season of Slow Horses will see the Slough House team on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge. It will be based on the novels Joe Country and Slough House.

The cast includes Gary Oldman, Kristin Scott Thomas, Jack Lowden, Saskia Reeves, Christopher Chung, Aimee-Ffion Edwards, Rosalind Eleazar, Joanna Scanlan, Samuel West, Ruth Bradley, Tom Brooke, Jonathan Pryce, and Hugo Weaving, alongside new addition Lenny Rush. Additionally, Olivia Cooke will return to her role as Sid Baker (last seen in the first season).

It will premiere globally on Apple TV on Wednesday, September 16, with the first episode, followed by one episode weekly until October 21.
