Just before season five of Slow Horses premiered a year ago, Apple TV showed a big gesture in commitment to the series by renewing Slow Horses for a seventh season. Then, it had revealed, “In Season 6, the spies head out on the run as Diana Taverner (Kristin Scott Thomas) embroils them all in a fatally high-stakes game of retaliation and revenge. The sixth season will be based on Mick Herron’s novels Joe Country and Slough House, which are the sixth and seventh books in the series.”
Apple TV has now released the new trailer for the sixth season, and Gary Oldman‘s Jackson Lamb is looking for answers after his Slow Horses start getting picked off one by one. The ensemble cast includes Academy Award nominee Kristin Scott Thomas, Emmy Award 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, Academy Award nominee Jonathan Pryce and Hugo Weaving, alongside new addition, BAFTA TV Award winner Lenny Rush. Additionally, Olivia Cooke will reprise her role as Sidonie “Sid” Baker in the sixth season.
In the official synopsis, Slow Horses is revealed to be a “darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known unaffectionately as Slough House. Oldman stars as Jackson Lamb, the brilliant but cantankerous leader of the spies who end up in Slough House due to their career-ending mistakes and who frequently find themselves blundering around the smoke and mirrors of the espionage world. Season six sees the Slow Horses on the run as Diana Taverner embroils them all in a fatally high-stakes game of retaliation and revenge.”
Season six has been produced by See-Saw Films, with Jamie Laurenson, Hakan Kousetta, Julian Stevens, Iain Canning, Emile Sherman, Adam Randall, Gail Mutrux, Douglas Urbanski and Oldman serving as executive producers. The season has been adapted for television by co-executive producer Gaby Chiappe.
The six-episode season is due to premiere on Apple TV starting on Wednesday, September 16.
