Apple TV+ has released a first look image of Season 5 of ‘Slow Horses‘, its Emmy and BAFTA Award-winning espionage drama starring Gary Oldman, confirming the six-episode season will premiere globally in September 2025.
Based on London Rules, the fifth book in Mick Herron’s award-winning Slough House series, the upcoming season continues the darkly witty saga of Britain’s most dysfunctional MI5 agents. The espionage drama follows a misfit team of British intelligence agents who serve in a dumping ground department of MI5 known unaffectionately as Slough House. Oldman, who has been honoured with Golden Globe, Emmy and BAFTA Award nominations for his performance, stars as Jackson Lamb, the brilliant but cantankerous 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.
What’s Season 5 About?
When resident tech nerd Roddy Ho suddenly has a glamorous new girlfriend, the entire office becomes suspicious. As a string of bizarre events begins to unfold across London, it falls to the misfit spies of Slough House to uncover the connection. At the centre of it all, Jackson Lamb (played by Gary Oldman – Tinker Tailor Soldier Spy, The Darkest Hour) knows one thing for certain: when it comes to the world of espionage, the London Rules — “cover your back” — always apply.
Returning Cast & Guest Stars
The returning ensemble includes Kristin Scott Thomas (Fleabag), Jack Lowden (Dunkirk), Saskia Reeves (Luther), Rosalind Eleazar (Rellik), Christopher Chung (Waterloo Road), Aimee-Ffion Edwards (Peaky Blinders), Ruth Bradley (Humans), James Callis (Battlestar Galactica), Tom Brooke (Sherlock) and Jonathan Pryce (The Crown). Season 5 will also feature Nick Mohammed (Ted Lasso) as a special guest star.
