Les Misérables, the enduring musical phenomenon adapted from Victor Hugo’s sweeping novel, has extended its West End run at the Sondheim Theatre through to March 2027. Producer Cameron Mackintosh confirmed the news on Thursday, adding seven months to the show’s schedule amid unrelenting demand as it marks 41 years since its London premiere.

This latest booking period, with tickets on sale from 5 March, cements Les Mis’s status as the world’s longest-running musical, a title it has held with defiant tenacity through economic turbulence and shifting tastes. Directed by James Powell and Laurence Connor, the current production boasts Matt Kinley’s evocative designs inspired by Hugo’s own paintings, alongside Paule Constable’s atmospheric lighting and the score’s timeless anthems – think “I Dreamed a Dream” and “One Day More” – that continue to pack the 1,000-seat venue on Shaftesbury Avenue.

Fresh casting bolsters the line-up this month, with Harry Hepple and Lizzie Bea stepping into the nefarious roles of Thénardier and Madame Thénardier, while Jess Folley, a WhatsOnStage award nominee, takes on the fiery Éponine. Their arrivals inject new vitality into a story of revolution, redemption and raw human struggle that first gripped audiences in 1985.

The extension arrives in buoyant company: Mackintosh also prolonged runs for The Phantom of the Opera, Hamilton and Oliver! into 2027, a vote of confidence in London’s theatre scene as it navigates post-pandemic recovery and the cost-of-living squeeze. Performances last 2 hours 50 minutes, interval included, with seats starting from £25. For those yet to witness Jean Valjean’s odyssey, the barricades await.
