Production Accelerates Despite Creative Changes

Slow Horses is undergoing its most significant behind-the-scenes transition since its 2022 debut. Original showrunner Will Smith departed after Season 5, with Gaby Chiappe taking the reins for Season 6. Ben Vanstone will subsequently lead Season 7, which Apple TV+ greenlit alongside Season 6 in July 2025.movieweb+3

"This was Will's last show, season 5, and we had a whole new team come in," Oldman revealed in a recent interview with ScreenRant. "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".screenrant+1

The rapid production timeline reflects Apple TV+'s confidence in the series, which has consistently delivered critical acclaim and strong audience numbers. Unlike many streaming shows that face lengthy gaps between seasons, Slow Horses has maintained its annual release schedule through efficient pre-production planning and the ready availability of Herron's source material.

High-Stakes Plot Promises Intense Season

Based on the Season 5 finale teaser, Season 6 will thrust Jackson Lamb and his team into their most perilous situation yet. According to Apple TV+, "the spies find themselves on the run as Diana Taverner draws them into a dangerously high-stakes game of vengeance and retaliation".decider+1

The preview footage revealed that a stolen file containing the Slow Horses' names has put the entire team in mortal danger, forcing them to operate completely off the grid. Kristin Scott Thomas's Diana Taverner appears to be orchestrating a revenge plot that could erase Slough House from official MI5 records entirely.red94+1

Joe Country and Slough House, the novels being adapted, explore themes of betrayal within British intelligence against the backdrop of Brexit-era political upheaval. The combined narrative promises to deliver the series' signature blend of dark humor and high-stakes espionage action that has earned it Emmy and BAFTA recognition.radiotimes+1
