Les Misérables London cast: who's on stage this season

The current London production of Les Misérables at the Sondheim Theatre features a rotating ensemble of principal and supporting actors, with Jean Valjean played by Ian McIntosh and Javert by Sam Oladeinde; the show also stars Katie Hall as Fantine, Adam Gillen as Thénardier, Claire Machin as Madame Thénardier, Thiago Phillip Felizardo as Marius, Amena El-kindy as Éponine, Joe Griffiths-Brown as Enjolras, and Izzi Levine as Cosette. Valjean and Javert are the anchors of the narrative, around which the rest of the company weaves a tapestry of love, sacrifice, and revolution.

Current principal cast

From the latest published company notes, Ian McIntosh continues to embody Jean Valjean, delivering a measured, gravitas-filled arc that anchors the show's moral compass; Sam Oladeinde performs Javert with a crisp vocal edge and courtroomly menace, providing a counterpoint to Valjean's redemptive progression. Fantine is portrayed by Katie Hall, whose renditions of I Dreamed a Dream have become a signature moment for audiences, while Adam Gillen's Thénardier brings a mischievous energy that lightens the darker passages.

In recent seasons, the company has maintained a schedule of understudies and alternate casts to cover absences, with notable understudies stepping in during holidays and weekend runs to preserve the show's tempo. The production's directorate confirms that these understudies perform to the same high standards as the principal cast, ensuring a seamless transition during any performance change. Underscores and vocal alternates are published in the show's official notices, making it easier for fans to confirm the on-stage line-up for any given evening.

Seasonal changes and anniversary specifics

During the 40th anniversary season, the company employed an expanded cast rotation to highlight multiple interpretations of the core roles and to honor the production's long legacy. Killian Donnelly has historically appeared as Jean Valjean during special performances, with Ian McIntosh occasionally stepping in for certain dates; this practice illustrates the show's commitment to delivering both consistency and a touch of variety across different performances. 40th anniversary programming reinforced the principal line-up and introduced high-profile guest appearances for limited engagements.

"Les Misérables is a living history of London theatre, and our cast rotations reflect the show's enduring energy," said a Sondheim Theatre spokesperson in 2025.

From July 2025, a new core cast was announced for long-running runs, including McIntosh and Oladeinde in lead positions, with Hall, Gillen, Machin, Felizardo, El-kindy, Griffiths-Brown, and Levine forming the backbone of the new company. News outlets captured the shift as part of the show's ongoing evolution, signaling to audiences that the musical remains an active, fresher-than-ever experience. London theatre coverage highlighted the changes as part of a broader West End refresh alongside other long-running titles.

Historical context and performance cadence

Since its West End debut in 1985, Les Misérables has sustained a demanding schedule, typically presenting 8-10 performances per week with occasional matinees. The present London run continues that rhythm, balancing principal performances with understudy coverage to maintain vocal health and dramatic intensity. The current troupe positions themselves within a lineage that includes iconic interpreters of Valjean, Javert, and the other leading roles, all of whom contributed to the musical's status as a London staple. West End rhythm remains a defining characteristic of the show's enduring appeal.
