A Wild Update About ‘Slow Horses’ Season 5, 6 And 7 On Apple TV+

In 2025, there are the 95% of streaming shows that are taking anywhere from 1.5 to 3 years to put out new seasons, and there is Slow Horses. At this point, the Apple TV+ spy show is an anomaly like nothing in the current market, as this latest update from Deadline demonstrates.

Slow Horses has been making new seasons at absolutely blinding speed, and this new update shows just how crazy it’s getting:

• Slow Horses season 5 will air in September 2025
• Slow Horses season 6 has already finished filming
• Slow Horses season 7 will start shooting in September or October 2025

Usually, a way to get a season out relatively quickly is to be on top of things to the point where you can be writing or even shooting as the current season is airing. But you read that correctly, the next season is already finished before season 5 is airing, and then the season after that, season 7, will be filming as season 5 is airing. I’m not sure there is anything like this happening in the market, even on more traditional broadcast TV.

Slow Horses season 1 was released in April 2022. We will now get season 5 in September 2025, five seasons in three and a half years. Then what, six seasons in four? Seven seasons in five? It’s certainly possible at this pace. It helps that the seasons are six episodes long, but even still, it’s something of a miracle.

It’s not as if the show is pumping out garbage. Quite the opposite. The series is one of the best on TV, landing Best Drama nominations for the series and Best Actor in a Drama nominations for star Gary Oldman, the recently knighted actor who says he will play the Jackson Lamb role forever, which is no doubt pleasing to Apple. The series has a 98% critic score across its four seasons, perfect 100s for seasons 2 and 4, 98% for season 3 and 95% for season 1. Again, there’s nothing quite like this on TV.

However, Slow Horses is somewhat cursed with the Apple TV+ association due to the fact that every time I try to bring the series up, almost no one has seen it, and few are even aware it exists. It’s yet another example of Apple TV+ arguably being the best streaming service, given its proportion of great shows paired with how few people actually subscribe to it or watch it. It’s unfortunate, and I recommend checking it out immediately. You have four seasons you can binge already.
