Slow Horses breaks an Apple TV+ record with season 6 renewal

But enough doom and gloom—congrats to everyone’s favorite dysfunctional intelligence agents! Based on Mick Herron’s Slough House novels, Slow Horses follows a group of MI5 agents confined to paperwork hell who still continuously find themselves mixed up in schemes, plots, and ever-present danger. In a press release, Apple TV+ revealed that 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.” 

Slow Horses‘ upcoming fifth season will be based on London Rules, the fifth book in Herron’s series. That book sees London face a series of terrorist attacks at the same time as Slow Horse Roddy Ho (Christopher Chung) must save himself from a series of attempts on his own life. Season five will premiere sometime in 2025; season four just wrapped up this past Wednesday. 

“I’m very committed to the show. I consider it very much a highlight of my career,” Oldman shared with The A.V. Club in a recent interview. “The bonus, really—and the surprise of doing it—is this sort of company feel that we have,” he continued. “I’m very fond of [the cast]. They’re just an amazing, really lovely group of people who I think have inhabited these characters and just do a brilliant job. So in terms of just the sheer day-to-day working of it, it’s not a chore, not a hardship. I love being around them. I think it’s pedigree stuff.”

In addition to those already mentioned, Slow Horses also stars Kristin Scott Thomas, Saskia Reeves, Rosalind Eleazar, Samuel West, Aimee-Ffion Edwards, Ruth Bradley, Tom Brooke, Joanna Scanlan, and Jonathan Pryce.
