What The Renewal Means For Slow Horses

The Sixth Installment Will Have A Bigger Story

It’s hard to tell how season 6 will look, given that season 5 has yet to debut. But it’s worth noting that the adaptation’s most recent finale might be its most consequential. River has to put his grandfather (played by Jonathan Pryce) in a retirement home. Marcus (Kadiff Kirwan) dies, which impacts Shirley (Aimee-Ffion Edwards) the most. Diana has to deal with two new faces, such as Claude (James Callis) and Emma (Ruth Bradley), both of whom will be back forSlow Horsesseason 5.

How Accurate Is Slow Horses? 6 Things The Show Gets Wrong About MI5

Based on the Slough House novels by Mick Herron, Slow Horses isn’t a totally accurate depiction of MI5, though the spy thriller nails some details.

But perhaps the biggest development is that the villainous Frank Harkness (Hugo Weaving) is revealed to be River’s father, with Diana seemingly having to let Harkness go after being outmaneuvered. The show’s 2025 return will include a bigger spotlight on Roddy Ho (Christopher Chung), as he’ll be the target of what seems to be an apparent assassination attempt. The fifth installment will be based on the novelLondon Rules.

Slow Horsesseason 7 has not been confirmed. Oldman, as the lead star, and series creator Will Smith have both said in interviews that they’d be happy to continue the story in its current form, downplaying possible spinoff avenues like a prequel. Given the series' recent jump in acclaim, with both audiences and more broadly,talk of a final season does not seem to be in the immediate future. With the early renewal for season 6, this means that the show can comfortably set up more ongoing storylines without the fear of being cancelled.

Apple’s Approach Is Paying Off

Although it is often downplayed or outright ignored in media reports, Apple TV+ does have a global presence. The streamer is clearly smaller in the U.S., butshows likeSlow Horseshave found an audience in the U.K. and other countries. With the Emmy nominations and consistent release schedule, it is also beginning to pick up positive word-of-mouth in the U.S. With the current release schedule, season 6 will likely air in 2026.
