Slow Horses Drops Major Hint: Seasons 6 and 7 Release Dates Could Be Closer Than You Think
Slow Horses is gearing up for a double mission: a fresh update teases release windows for Seasons 6 and 7, and Gary Oldman says cameras roll on the next chapter as soon as Season 6 wraps, as Apple TV+ keeps driving Mick Herron’s Slough House saga forward.
Apple TV+'s best grumpy-spy show is not slowing down. Gary Oldman just dropped a tidy little update that quietly points to when we should expect Slow Horses Seasons 6 and 7, and it also confirms the show is basically running like a relay race behind the scenes.
Oldman, who plays the eternally rumpled Jackson Lamb, said Season 6 has already finished filming and Season 7 is up next, starting at the end of October. If you do the math on how this series rolls out, that lines up with Season 6 landing in 2026 and Season 7 in 2027.
"This was Will's last show, Season 5, and we had a whole new team come in. We've already shot Season 6, it's in the can, and at the end of October, we start Season 7, and that's a new team."
Quick context check: Slow Horses premiered back in April 2022 and adapts Mick Herron's Slough House novels, one book per season. The hook is simple and great — a squad of sidelined MI5 agents getting dumped on by bureaucracy, then somehow saving the day anyway. The main crew includes Gary Oldman, Jack Lowden, Kristin Scott Thomas, Sophie Okonedo, Jonathan Pryce, Hugo Weaving, Saskia Reeves, Rosalind Eleazar, Christopher Chung, and Aimee-Ffion Edwards.
Inside baseball worth knowing: the series was developed for TV by writer-producer Will Smith (no, not that one), who always planned it as a long-haul project. He exits after Season 5, and per Oldman, a new creative team is already in place for Season 6 and again for Season 7. Apple TV+ officially renewed the show through at least Season 7 in July 2025, which explains why the machine keeps humming while new episodes are still airing.
That overlap is unusual for streamers, but it fits this show. With Herron's books serving as clean, season-sized blueprints, Apple seems comfortable shooting back-to-back and banking episodes. Season 5 is airing now, Season 6 is done, and Season 7 cameras roll at the end of October — the kind of steady cadence that makes those 2026 and 2027 windows feel realistic, not wishful thinking.
- Premiered: April 2022 on Apple TV+
- Source material: Mick Herron's Slough House novels (one book per season)
- Current status: Season 5 is airing; Season 6 is wrapped; Season 7 starts filming at the end of October

Bottom line: the pace is brisk, the plan is clear, and the show has quietly become one of Apple TV+'s most consistently acclaimed originals. Works for me.
