Gary Oldman has long been a chameleon of cinema, shifting from menacing villains to historical icons. But his latest role as the disheveled, flatulent, yet brilliant spy Jackson Lamb might be his most captivating yet. The actor, who looks like he hasn't updated his wardrobe since the Cold War, is leading Slow Horses to unprecedented heights on Apple TV+.

The series, based on Mick Herron's bestselling novels, has officially claimed the No. 1 spot on the streaming platform, dethroning the beloved Ted Lasso. This achievement comes as Season 6 continues to enthrall audiences with its razor-sharp writing and tense espionage. The show follows a team of MI5 misfits relegated to Slough House, a bureaucratic dead-end for agents who've botched their careers. Yet, these so-called failures keep proving they're too competent to fail, especially when entangled in Diana Taverner's deadly games of revenge.

Oldman leads a stellar cast including Jack Lowden as River Cartwright, Kristin Scott Thomas as the formidable Diana Taverner, and Saskia Reeves as Catherine Standish. The ensemble also features Rosalind Eleazar, Christopher Chung, and Aimee-Ffion Edwards, each bringing depth to their flawed, endearing characters. Their chemistry is a key reason the show resonates so deeply with viewers.

Why 'Slow Horses' Keeps Winning

Since its 2022 debut, Slow Horses has been a critical darling, but its true strength lies in its relentless consistency. Six seasons in just four years is a feat few shows manage, especially when compared to the lengthy gaps between seasons of other hits. The shorter, tightly paced seasons—each adapting one of Herron's novels—keep the narrative brisk and addictive, a refreshing change from sprawling, meandering spy dramas.

The show's popularity isn't just about viewership; it's an awards magnet. With 23 Emmy nominations and three wins, including Outstanding Writing in 2024 and Outstanding Directing in 2026, Slow Horses has cemented its legacy. It's also a BAFTA favorite, taking home trophies for writing, editing, and sound across multiple seasons.

For those new to the series, it's a perfect entry point into the spy genre.

As Slow Horses continues to dominate, it's clear that Oldman's grumpy spy has become a cultural touchstone. The show's blend of wit, grit, and heart makes it a must-watch, and its streaming success is well-deserved. Catch all six seasons exclusively on Apple TV+.
