Jamie Muscato is having a moment. From The Emcee at the Kit Kat Club to Jay Gatsby at the London Coliseum, he's proving himself the definitive leading man of this generation's West End — and now Dexter feels like his crowning role.
Insiders note that Muscato's October Phantom gig at the Palladium gives him a tight window between Love Never Dies and One Day. Some are whispering about whether the scheduling is intentional — or if there's real pressure to lock in before another name gets floated.
The Edinburgh production opened March 2026 at Royal Lyceum Theatre with Muscato as Dexter and Sharon Rose (Hamilton) as Emma. David Nicholls' novel has sold over six million copies worldwide, been translated into 40+ languages, and grossed nearly $60M from the 2011 Anne Hathaway film.
With One Day's proven source material and Muscato's current hot streak, this West End transfer feels less like a gamble and more like inevitability. The real question: which London theater will get to host the hype?
One Day: The Musical is officially making the leap from Edinburgh to the bright lights of the West End — and sources confirm Jamie Muscato is in advanced talks to reprise the role that put him back in the spotlight this spring. A production insider spilled to The Hollywood Reporter that the transfer, which has been rumored since the Edinburgh run opened at Royal Lyceum Theatre in March 2026, is now a go.
Muscato, fresh off his electric turn as The Emcee in Cabaret at the Kit Kat Club, is being eyed once again for Dexter — the complex, emotionally devastating character at the center of David Nicholls' beloved novel. Sharon Rose, who originated Emma opposite Muscato's Dexter in Edinburgh (and whose credits include Hamilton), would presumably make the journey to London as well, though the source didn't confirm her involvement explicitly. The musical tracks the enduring bond between Dex and Emma from their first meeting on July 15, 1988 — St Swithin's Day — through decades of life-changing moments that unfold on the same date each year.
The adaptation is crafted by David Greig with songs by Abner and Amanda Ramirez of Johnnyswim and additional music by Freya Catrin Smith. Max Webster, whose directing credits include Life of Pi and The Importance of Being Earnest, helmed the production. This team assembled around Nicholls' property — which has moved 6 million copies globally across 40 languages — speaks to serious industry confidence in the material.
But here's where it gets interesting for those of us who track these things: Muscato is also set to play The Phantom in concert performances of Love Never Dies at the London Palladium this October. That's a tight turnaround, and sources will be watching closely to see how the scheduling shakes out — or whether another name starts circulating if negotiations stall. Still, you can't argue with the trajectory.
Muscato's body of work reads like a greatest-hits reel of prestige theater: Moulin Rouge! The Musical, Heathers, his Olivier-nominated turn in Natasha, Pierre & The Great Comet of 1812, and last year's Jay Gatsby at the London Coliseum alongside Frances Mayli McCann, Corbin Bleu, and Amber Davies. If One Day lands him back on stage in London's West End as Dexter, it won't just be another role — it'll be a statement.
Previous adaptations already proved the appetite is there: Netflix's series with Leo Woodall and Ambika Mod sent both actors into global fame, while the 2011 film starring Anne Hathaway and Jim Sturgess raked in nearly $60 million at the box office. The question now isn't whether One Day belongs on the West End — it's which theater gets the honor of hosting what could be the season's most talked-about transfer.
