'Slow Horses' Star Reveals Gruesome Details of Brutal Finale Showdown!

The sixth season of Apple TV+'s spy thriller, Slow Horses, concluded with a high-stakes finale, leaving the fates of several key characters uncertain. The episode, titled "Judgment Day," saw River Cartwright's potentially dangerous pursuit of a romantic future with Sid Baker, while the Slow Horses confronted their deadliest threats yet: River's biological father, mercenary Frank Harkness (Hugo Weaving), and the ruthless Russian assassin Jane (MyAnna Buring). The convergence of these forces at Diana Taverner's (Kristin Scott Thomas) beach house created a tense climax, with Jackson Lamb (Gary Oldman) navigating perilous choices to protect his team.

MyAnna Buring, a self-professed fan of Slow Horses, shared her insights into her role as the enigmatic and terrifying Jane. She described a mix of trepidation and immense excitement joining a well-established show, particularly working with director Adam Randall and co-star Kyle Soller, who played Jim. Buring emphasized the importance of creating a deep backstory for Jane and Jim, revealing they envisioned the characters as having grown up together in an orphanage, forming an unbreakable bond as each other's only family. This shared history allowed for spontaneous improvisations on set, such as a subtle touch in a car park scene, which conveyed their deep connection.

A poignant improvisational moment involved a "childlike" song Buring hummed after Jim's death. She wanted it to be a tune from their youth, offering comfort during dark times, further cementing their familial connection. Buring noted that this collaborative spirit, encouraging "little moments" and improvisation, is a hallmark of Slow Horses and its cast.

As the mission devolved, Buring aimed to convey Jane's unraveling state of mind. She portrayed Jane's journey from a seemingly professional agent to one dealing with "dangerous morons," leading to a "psychotic glee" as the mission became increasingly personal, especially after Jim's demise and the pursuit of River and Sid.

Reflecting on the action sequences, Buring highlighted the fight between Kyle Soller (Jim) and Tom Brooke (Coe) as particularly moving, calling it a "beautiful metaphor." For her, the most memorable was the final, "no holds barred" fight with Jack Lowden (River). She praised Lowden's professionalism and willingness to engage physically, enjoying the intensity of the "messy," "feral" choreography that eschewed elegance for a raw, realistic portrayal of combat.

Jane's unexpected and abrupt end at the hands of Frank Harkness was a moment Buring appreciated for its "comic, delightful energy" and surprising impact. She viewed her character's swift exit as a crucial "surprising note" in the story's "symphony." In a testament to her dedication and fan enthusiasm, Buring revealed she lay on the set, covered in fake blood and bullet holes, for an entire afternoon after Jane's death scene to witness Hugo Weaving and Jack Lowden perform their father-and-son conversation. This "blink-and-you'll-miss-it cameo" allowed her to enjoy watching two of her favorite actors, fulfilling a "wild fantasy" as a true fan of the show. All six seasons of Slow Horses are now streaming on Apple TV, with a seventh season confirmed.
