On screen, the relationship between Thomas Shelby and his older brother Arthur Shelby in the British drama Peaky Blinders is arguably one of the most volatile and complex bonds in television history. Tommy, played by Cillian Murphy, is the cold, calculating strategist, constantly manipulating his more volatile sibling. Arthur, played by Paul Anderson, is a scarred, emotionally tormented powder keg of violence. Their on-screen relationship is defined by trauma, power, and high-stakes confrontation.
The intensity of this dynamic was so real that Cillian Murphy himself once admitted it was deeply unsettling. He shared in interviews that Paul Anderson’s total immersion in the role of Arthur—the wild eyes and unpredictable unpredictable—could truly make him “afraid” of that raw, visceral look . It was, as the Oscar-winner described it, “pure fear, not real violence” that he felt while working opposite his co-star. This speaks volumes about the immersive nature of Anderson’s ferocious, full-throttle performance.
However, the moment the director yelled “Cut,” the tension instantly disappeared. It was immediately replaced by a genuine bond of deep affection and mutual respect. This beautiful, untold truth reveals that Cillian Murphy and Paul Anderson are the closest of friends and true creative brothers in real life. Murphy often promotes Anderson as the “heart” of the film, a true anchor for the series.
Their close working relationship was built on years of collaboration and deep friendship. This bond allows them to dive into the strictly necessary of the Shelby brothers’ dynamic, knowing that a hug and a laugh were waiting the moment the cameras stopped rolling. They even shared film history outside of the Birmingham streets of Peaky Blinders . Murphy and Anderson starred together in the 2015 historical drama In the Heart of the Sea . Anderson recalled joking with Murphy on that set, yelling “Tommy!” and “Arthur! What the bloody hell are we doing here?” when they found themselves together on a boat in the Atlantic Ocean.
The six-series run of Peaky Blinders culminated in 2022. But the story is set to continue with a feature-length film, The Immortal Man , scheduled to begin filming in 2024. The willingness of both actors to return to these iconic and demanding roles underscores the collaborative spirit and personal commitment they share, determined to encompass the Steven Knight saga together.
The real bond between the actors is a profound reminder that the darkest, most intense on-screen performances often require the strongest personal connections behind the scenes. This deep, supportive friendship was the grounding force that allowed the characters’ violence to be so believable—and so brilliant.
