Brendan Gleeson makes his West End debut at the Harold Pinter Theatre, starring as Jack in Conor McPherson’s The Weir. The revival of the Irish drama is set on a rain-soaked night in 1996 at a remote pub on Ireland’s west coast, where three local men and the barman swap ghost stories as a Dublin newcomer, Valerie, arrives with a tale that unsettles the room.

Alongside Gleeson, Owen McDonnell plays the barman Brendan, Tom Vaughan-Lawlor is Finbar, and Sean McGinley portrays Jim, the trio whose stories accumulate in McPherson’s lyrical dialogue. Kate Phillips plays Valerie, a mysterious Dublin woman whose visit becomes the evening’s hinge and gives the play its turning moment.

Gleeson’s Jack cuts a craggy, bearlike figure who dominates the room, a man who drinks bottled Guinness because the tap is faulty and whose presence anchors the ensemble. His delivery wanders into a florid, almost mythic cadence at times, but the actor’s instinct for McPherson’s lilting Irish poetry keeps the storytelling buoyant. The cast around him—McDonnell’s steady barman, Vaughan-Lawlor’s jittery Finbar, and McGinley’s Jim—relish the balance of menace, warmth, and wit as the evening unfolds.

Phillips’s Valerie arrives with a blunt, unsettling backstory that reframes the exchange and sends the characters’ well-worn tales spiraling toward a painful truth. The Weir, first staged in 1997, remains potent almost 30 years on, capturing a country on the cusp of change and haunted by a mythic past. The production invites the audience to listen as much as to watch, leaning into McPherson’s skill for turning a barroom yarn into a mirror of collective memory and fear. Gleeson’s West End debut is described as a commanding, if occasionally audibly imperfect, performance that nonetheless embodies the play’s hypnotic blend of storytelling and mood.

Set in the pocket of a small-town Irish life, the play unfolds in a single room where the weather outside seems to press in through the walls. The barman Brendan serves as the steady spine of the night, keeping order as the men press their stories against the damp air. Finbar and Jim offer counterpoints—one with flirtations of bravado, the other with a more spectral, almost ghostly presence—creating a chorus of voices that McPherson uses to explore how myth and memory shape people’s choices and fears. The arrival of Valerie, with her own tale, disrupts the ritual and forces the room to confront the truth behind the legends they tell.

The production’s atmosphere leans into the quiet, smoky intimacy of a pub stage, where laughter erupts with warmth even as the night sours into something unsettled and uncanny. In this revival, the play’s mood remains as potent as ever: a slow-blooming tension that answers the question of what it means to be haunted by a past you cannot outrun. Critics note the ensemble’s timing as a crucial ingredient, allowing the humor to land just as the terrors begin to insinuate themselves into the room’s fabric. Gleeson’s contribution, built on a career steeped in both screen and stage work, is to balance that weight with a presence that feels almost elemental—part folklore, part weather pattern, wholly compelling.

Nearly three decades after its premiere, The Weir endures because it captures a moment in Irish life when old beliefs and modern realities collide. The village’s myths act as a communal memory, a way to process loneliness, aging, and the pull of change as Ireland moves toward a new era. The play’s ability to revolve around a single, intimate setting while addressing universal themes of fear, solace, and belonging is a testament to McPherson’s craftsmanship and to Gleeson’s striking stage entrance, which has the audience leaning in from the moment the doors close and the rain begins to fall outside.

In sum, this West End staging of The Weir offers a reminder that the most powerful thrill in theater can be found in a small room, with a few faces, and a storyteller who knows how to bend a tale until it creaks with truth. Gleeson’s debut in London’s theatre scene arrives amid a strong ensemble, precise direction, and a script that continues to invite audiences to listen closely to the quiet, uncanny music of a night spent at the bar with the living and the ghosts of Ireland.
