Slow Horses | Series 4 Preview (Apple TV+)

Adapted from Spook Street, the fourth novel in the CWA Gold Dagger Award-winning Mick Herron spy series Slough House, season four of Slow Horses will premiere globally on Wednesday, September 4 with the first two episodes, followed by one new episode weekly, every Wednesday through October 2, on Apple TV+.

“Slow Horses” is a darkly humorous espionage drama that follows a dysfunctional team of British intelligence agents who serve in a dumping ground department of MI5 known un-affectionately as Slough House. Season four opens with a bombing that detonates personal secrets, rocking the already unstable foundations of Slough House. 

Oldman stars as Jackson Lamb, the brilliant but misanthropic leader of the spies, who end up in Slough House due to their career-ending mistakes as they frequently find themselves blundering around the smoke and mirrors of the espionage world.

The returning ensemble cast also includes Academy Award-nominee Kristin Scott Thomas, BAFTA Scotland Award-winner Jack Lowden, Saskia Reeves, Rosalind Eleazar, Christopher Chung, Aimee-Ffion Edwards, Kadiff Kirwan and Academy Award-nominee Jonathan Pryce. SAG Winner Hugo Weaving, BAFTA winner Joanna Scanlan, IFTA winner Ruth Bradley, Tom Brooke and James Callis join “Slow Horses” in season four.

“Slow Horses" is produced for Apple TV+ by See-Saw Films and adapted for television by Will Smith (“Veep”). Jamie Laurenson, Hakan Kousetta, Iain Canning, Emile Sherman, Jane Robertson, Julian Stevens, Douglas Urbanski, Gail Mutrux, Graham Yost and Will Smith serve as executive producers on the series. Season four is directed by Adam Randall.

Fans can catch up on the first three seasons of “Slow Horses,” which all hold a Certified Fresh score on Rotten Tomatoes, now streaming globally on Apple TV+. In addition to the upcoming fourth season, Apple TV+ recently announced a fifth season set to be adapted from the fifth novel, “London Rules.”

Since its premiere in 2022, “Slow Horses” has won two BAFTA Television Awards while earning nine additional nominations.
