Will Smith Exits Hit Spy Drama Slow Horses After Season 5: What This Means for the Show and Beyond

Apple TV+’s acclaimed spy thriller Slow Horses is gearing up for its much-anticipated fifth season, but fans will soon see a significant change behind the scenes. Will Smith—the writer, executive producer, and creative force behind the adaptation of Mick Herron’s beloved Slough House novels—has announced that he will step away from the series after Season 5. This marks a pivotal moment in the show’s journey, signaling the end of an era while opening doors for fresh creative voices.

A Perfect Time to Pass the Torch

Smith, who has steered Slow Horses from its inception as its de facto showrunner, says this decision comes at a natural pause in the story. Season 5 wraps up several major story arcs that began in Season 1, making it an ideal moment to hand over creative control. Speaking to Deadline, Smith emphasized his desire to maintain the show’s quality and originality without overstaying his welcome:

“Season 5 doesn’t end things by any means, but it concludes certain story arcs that started in Season 1, so it felt like a good moment to hand over the show.” He also expressed his wish to leave while the show remains fresh and fun, avoiding the pitfalls of repetitive storytelling.

The increasing intensity of the production schedule also played a role in Smith’s decision, though he assured fans he’s stepping away on good terms with the cast, crew, and source material.

What’s Next for Slow Horses and Its Creators?

Apple has renewed Slow Horses for Seasons 6 and 7, with new lead writers Gaby Chiappe and Ben Vanstone stepping in to continue the saga. Meanwhile, Smith is not abandoning the Slough House universe entirely. His passion project is adapting The Secret Hours, a standalone novel by Mick Herron that serves as a prequel and side story to the main series. Smith envisions it as either a standalone film or a short miniseries, highlighting the potential for expanding this rich spy world beyond the current storyline.

In addition to this, Smith is developing other projects, including a TV adaptation of Andrew O’Hagan’s novel Caledonian Road and The Siege, based on Ben Macintyre’s book about the 1980 Iranian Embassy crisis in London.

Season 5 of Slow Horses premieres on Apple TV+ on September 24, with all previous seasons currently available to stream.

What Undercode Say: Analyzing the Impact of Will Smith’s Departure on Slow Horses and Apple TV+

Will Smith’s departure from Slow Horses after Season 5 is a significant moment for the series, Apple TV+, and the broader spy thriller genre on streaming platforms. His dual role as writer and executive producer has been integral in shaping the show’s tone, narrative style, and adaptation fidelity. This transition naturally raises questions about how the series might evolve with new leadership.

Smith’s choice to leave while the show is still strong is a strategic move that reflects a mature understanding of creative cycles in television. Many long-running shows suffer when original creators stay too long, leading to diminishing returns creatively and critically. By stepping aside now, Smith preserves his legacy and ensures that Slow Horses can continue without creative stagnation.

With Gaby Chiappe and Ben Vanstone taking over writing duties, the show is positioned to bring fresh perspectives while respecting the established tone. Both writers have strong backgrounds in British drama and crime storytelling, which aligns well with the world Mick Herron created.

The potential adaptation of The Secret Hours as a prequel or spin-off is particularly intriguing. It opens a window to deepen the lore of the Slough House universe and attract viewers who crave intricate, character-driven spy stories. If executed well, this could become a successful franchise extension, much like how Better Call Saul expanded the Breaking Bad universe.

Smith’s other projects, focusing on political and historical drama, suggest his continued interest in complex narratives grounded in reality but enriched by suspense. This bodes well for the quality of work we can expect from him post-Slow Horses.

From Apple TV+’s perspective, renewing Slow Horses through Season 7 underscores the platform’s commitment to high-quality British dramas that appeal to global audiences. It also illustrates how Apple is competing in the crowded streaming market by investing in well-written, character-rich shows with strong source material.

Overall, Smith’s departure is both an end and a beginning—closing a key chapter for Slow Horses while potentially paving the way for new stories within the same universe and new creative ventures for Smith himself.
