Derry Boys: A Must-See Play at Theatre503

Don’t be misled by the title. Derry Boys, now playing at Battersea’s Theatre503, is no spin-off of Derry Girls. The show wryly references the hit series as “Derry’s version of Black Panther,” but quickly sets itself apart with a voice that is entirely its own: bold, politically charged, and profoundly affecting.

Written by emerging playwright Niall McCarthy in an impressive full-length debut, the play spans three decades and follows the intertwined lives of Paddy and Mick: mischievous, croissant-thieving best friends from Derry (or Londonderry, depending on your politics). Set in a Northern Ireland well beyond the Troubles, in an era where peace is official but far from uncomplicated, their story is one of repeated reunions and growing ideological distance. Paddy becomes a politically engaged academic, campaigning for Irish unification through peaceful reform. Mick, meanwhile, veers into radicalism, embracing a violent neo IRA agenda. What unfolds is a nuanced, often heart-wrenching portrait of friendship tested by loyalty, conscience, and the weight of inherited trauma.

Despite its heavy themes, Derry Boys fizzes with wit and charm. The rapid-fire banter between the two leads is laugh-out-loud funny, yet grounded in emotional truth. I laughed. I cried. I was completely absorbed. McCarthy has crafted a piece of theatre that grabs hold early and never lets go. If there is one weakness, it lies in its compact running time. Some emotional beats, particularly in the second half, could have benefited from more breathing room. A longer runtime might have allowed certain character transitions to unfold with greater depth.

At the core of the production is the electric chemistry between Eoin Sweeney as the thoughtful, reformist Paddy and Matthew Blaney as the explosive, embittered Mick. This marks their fourth creative partnership and it shows. The familiarity between the two actors infuses every scene with lived-in ease and emotional nuance. Whether they are hurling insults, reminiscing over old times, or standing in strained, unspeakable silence, the connection between them feels authentic and utterly absorbing. They shift effortlessly between raucous comedy and aching vulnerability, capturing the rhythms of male friendship in all its contradictions: affection buried under bravado, resentment tangled with loyalty, and a fierce love that often goes unspoken. Their dynamic carries the production, moving fluidly between tenderness, tension, and explosive release.

They are joined by Catherine Rees, who brings dry humour and emotional ballast as Aoife, whose relationship with Paddy gently evolves from playful flirtation to the quiet endurance of a long suffering partner. In one particularly poignant moment, her simple presence onstage provides a stillness that cuts through the chaos, grounding the emotional tempo. She offers a steady counterpoint to the intensity of the central duo and becomes a vital emotional anchor in the story.

Under the deft direction of Andy McLeod, the production embraces a stripped back aesthetic that focuses attention on the emotional intensity of the performances. The set is grey, stark, and concrete, a multi use design that cleverly transforms into a variety of spaces across time and geography. With minimal adjustments and clever blocking, a single structure becomes a car, a cafe, a home, and an office. The visual austerity heightens the emotional stakes, ensuring the focus remains firmly on the characters and their evolving dynamics. Lighting shifts and spatial choreography do much of the heavy lifting, imbuing each scene with mood and momentum without ever distracting from the heart of the story.

Derry Boys is not just a triumph for its cast and creative team, but a bold declaration of what small scale new writing can achieve when it is given space and trust. It speaks directly to contemporary conversations around identity, masculinity, and post conflict legacy, while never losing sight of the human relationships at its core. It is rare to see a production so finely balanced between humour and heartbreak, or one that captures the complexity of male friendship with such honesty and emotional clarity. Every moment feels earned, every performance leaves a mark. This is the kind of theatre that reignites faith in the stage itself, proving that even in the smallest spaces, stories can erupt with truth, power, and unforgettable impact.

Derry Boys is playing at Theatre 503 in Battersea until 7th June 2025
