The power of visual identity in television is often underestimated, but sometimes a single aesthetic decision can transcend the screen and reshape global culture. That was precisely the case with Peaky Blinders, where one unexpected—and initially despised—choice became a defining symbol of modern style. At the center of this transformation was Cillian Murphy and the now-iconic haircut of his character, Tommy Shelby.
According to director Tom Harper, the look that would eventually define the series was never meant to be glamorous. In fact, it was designed to feel harsh, utilitarian, and almost unsettling. The shaved sides and longer top were inspired by early 20th-century working-class styles—practical cuts that reduced the risk of lice and made street fights less disadvantageous. It was a haircut rooted in survival, not fashion.
But when Murphy first saw himself in the mirror after the transformation, his reaction was immediate and visceral. He hated it. The sharp contrast of the shaved sides made him feel exposed, stripped of any sense of conventional attractiveness. For an actor known for his striking features and expressive eyes, the cut felt like a risk—one that could permanently alter how audiences perceived him.
That discomfort, however, became part of the character’s DNA. Tommy Shelby is not meant to be approachable or traditionally charming; he is cold, calculating, and emotionally guarded. The severity of the haircut amplified those traits, giving him an almost architectural presence—clean lines, no softness, no excess. What Murphy initially feared would undermine him instead sharpened his entire performance.
The irony is what followed. As Peaky Blinders gained global popularity, the so-called “Peaky cut” exploded beyond the screen. Barbershops across Europe, North America, and Asia reported a dramatic surge in requests for the same style—some estimates placing the increase at over 300%. What was once a historically practical haircut became a modern symbol of masculinity, confidence, and understated rebellion.
Men who had never heard of 1920s Birmingham gangs suddenly found themselves asking for shaved sides and a textured top. The look crossed cultural boundaries, appearing in fashion campaigns, music videos, and social media trends. It became more than a hairstyle; it became a statement.
For Murphy, the contradiction never fully disappeared. Even as the haircut helped turn Tommy Shelby into an enduring cultural icon, he remained aware of his initial reaction—the discomfort, the resistance, the sense that it was all a mistake. Yet, that tension may be exactly what made the performance so compelling. The unease translated into authenticity, reinforcing the character’s guarded and often intimidating presence.
In retrospect, this moment highlights one of the most fascinating aspects of storytelling: the elements actors resist the most can sometimes become the most powerful. A haircut that was never meant to be admired ended up redefining global style trends. An aesthetic choice born from historical necessity became a symbol of modern cool.
And at the heart of it all is a simple irony—what Cillian Murphy loathed, the world couldn’t get enough of.
