Les Misérables Marks 40 Years With Star-Studded Eight-Week West End Celebration

The world’s longest-running musical is throwing itself a birthday party that only Les Misérables could stage: a limited, eight-week anniversary engagement at the Sondheim Theatre, packed with a hand-picked cast of fan favourites and fresh faces from the show’s four-decade history.

A Milestone Worth Marching For

First unleashed on London audiences in October 1985, Boublil and Schönberg’s epic tale of sacrifice, revolution and redemption has survived venue moves, critical sniping and even a global pandemic to notch up 40 uninterrupted years in the West End. Producer Cameron Mackintosh calls the milestone “a very special birthday celebration indeed for the world’s longest-running musical,” and true to form he has assembled an ensemble designed to make even the most seasoned Les Mis devotee sit up and sing along.

A Dream Cast Reunited

Killian Donnelly returns to the barricades as Jean Valjean, fresh from sharing the role in the Les Misérables Arena Spectacular and a stint as Enjolras in the West End company.
Opposite him, Bradley Jaden straps on Javert’s tricolour sash—having previously shared Valjean’s nemesis in the arena tour and earned acclaim as Enjolras in London.
The principal line-up is rounded out by Katie Hall (Fantine), Jac Yarrow (Marius), Shan Ako (Éponine), Jordan Shaw (Enjolras) and Beatrice Penny-Touré (Cosette).
Comedy relief comes via Adam Gillen—fresh off Cabaret—as Thénardier, with Australian stage icon Marina Prior as Madame Thénardier.

Mackintosh hints that other veterans of international productions and even the Oscar-winning 2012 film may drop in for cameo appearances during the run.

Dates, Tickets and the Elusive Birthday Night

The anniversary company takes over the Sondheim Theatre from 8 September to 3 November 2025. While standard performances are already listed on major outlets such as TodayTix and LOVETheatre, tickets for the actual 40th birthday show on 8 October remain under wraps. Producers promise further details “very soon,” fuelling speculation that special guests—or even a live broadcast—could be in the works.

Why This Cast Matters

Both Donnelly and Jaden personify the show’s knack for nurturing talent. Each began in supporting roles before graduating to headline status, echoing the trajectory of alumni like Alfie Boe, Michael Ball and Ramin Karimloo. Their reunion—as adversaries this time—offers a rare chance to see two of the production’s most celebrated leading men share the same stage.

Meanwhile, rising star Jac Yarrow brings fresh energy to Marius after winning an Olivier nomination for Joseph and the Amazing Technicolor Dreamcoat, and Shan Ako steps back into Éponine’s boots, having first melted hearts in the show’s 2019 staged concert.

The Bigger Picture

This eight-week celebration also dovetails with the globe-trotting Les Misérables Arena Spectacular, which continues its world tour after smashing box-office records across the UK and Europe. Together, the arena production and the West End anniversary season underscore the brand’s enduring popularity—and its ability to evolve without losing its soul.

What to Expect

Audiences can anticipate the classic version of the musical—no live orchestral re-orchestrations or arena-style projections here—but you may notice subtle nods to the show’s history. Mackintosh is known for sprinkling anniversary performances with Easter eggs: original costume pieces, vintage staging flourishes, even surprise appearances during the rousing “One Day More.”

Final Curtain

Forty years ago, few predicted a sung-through adaptation of Victor Hugo’s 19th-century novel would outlive the Cold War, the CD, and arguably musical-theatre trends themselves. Yet Les Misérables marches on, banners flying, still filling Shaftesbury Avenue night after night.

If you’ve ever dreamed of hearing “Bring Him Home” live, sung by one of the role’s definitive interpreters, the clock is ticking: this anniversary cast bows out after eight short weeks, and the revolution will roll on without them.
