Irvine Welsh’s 1993 debut novel Trainspotting is adapting into a West End musical opening on July 15 at the Theatre Royal Haymarket, featuring original music by the author and Stephen McGuinness alongside selected songs from Danny Boyle’s celebrated film.
When the novel was first published, few predicted it would transcend underground cult status to become a cultural touchstone. More than three decades later, that literary breakout is taking perhaps its most unexpected form yet: a musical theatre production scheduled for the West End.
Bringing Leith to the West End Stage
Trainspotting the Musical runs at the Theatre Royal Haymarket until September 5 before heading out on tour. The production brings back the familiar ensemble of youth culture cult heroes—Renton, Sick Boy, Begbie, Spud, Tommy, and Kelly—alongside an ensemble cast and a live band.
The creative lineage behind stage and screen adaptations of the property spans decades. In 1994, director Harry Gibson brought an adaptation to the stage that relied on the ferocity of the author’s language. Ewen Bremner originated the role of Renton on stage in 1994, followed by Ewan McGregor in Danny Boyle’s film two years later. For this new musical iteration, 26-year-old Robbie Scott makes his West End debut stepping into the role of Renton, following credits at Pitlochry Festival Theatre where he starred in Peter Pan and Wendy
.
Writing a Proper Musical Theatre Score
Adapting gritty source material about heroin use and scams into musical numbers presented a distinct challenge. Welsh noted that he wanted to avoid the pitfalls of theatrical adaptations that either treat music as an afterthought or lean entirely into nostalgia.
“There are so many shows in the West End that are either stage plays with music perfunctorily thrown in or nostalgia pieces with unrelated music from the times. The only way I could see a Trainspotting musical work is if we could write our own songs that moved it along as a proper piece of musical theatre.”

That vision materialized when Welsh partnered with Stephen McGuinness. Following a soul- and disco-infused companion album released for Welsh’s 2025 novel Men in Love
, the pair collaborated on original music and lyrics for the production. Alongside these new tracks, the show incorporates selected songs from the film’s soundtrack. While rights negotiations played out, Welsh admitted it would feel strange not to include Iggy Pop’s Lust for Life
, and Clive Davis of The Times confirmed that Lou Reed’s anthem Perfect Day
made the cut.
Critical Division on Stage Direction and Tone
Directed by Caroline Jay Ranger—whose past work includes shepherding Only Fools and Horses
at the same venue—the production has sparked sharply divergent reactions from theater critics regarding its narrative coherence and visual choices.
Theo Bosanquet of London Theatre noted that the director certainly has form shepherding well-known IPs to the stage,
but observed struggles in establishing a strong narrative arc amid long sections of drug-taking. Arifa Akbar of The Guardian described the narrative as chopped up, with scenes running in a different order from the novel, moving from a group trip to Blackpool to Spud’s job interview and Begbie’s snooker-table violence.
Visual and auditory choices also drew debate. Alun Hood of WhatsOnStage characterized the staging as visually dark, noting that key moments unfold in gloom. Ben Lawrence of The Telegraph criticized the mix of original songs and added pop hits, arguing that seeing cynics like Renton and Sick Boy perform jazz hands undermines the power of the original characterizations.
Performances and Character Dynamics
Despite structural criticisms, individual performances earned praise across the reviewing corps. Gary Naylor writing for BroadwayWorld highlighted Frankie O’Connor’s menacing portrayal of Begbie—noting he looks and walks like Mark Rylance in Jerusalem—alongside Sheridan Townsley’s work as Sick Boy and Finlay Paul as Tommy. Clive Davis in The Times added that Paul successfully wins audience sympathy as his character’s life unravels.
Welsh defended the production’s underlying tone and creative leadership, praising Ranger’s theatrical instincts.
“She’s got the whole package. She understands the drama of it, she’s an ex-dancer so she understands the movement and, above all, she gets the humour. If you’re going to give people dark material, you have to have them laugh their tits off as well.”

Expanding the Source Material
To build out the theatrical world, the musical incorporates contextualizing material from Welsh’s 2012 prequel novel, Skagboys, alongside a couple of new characters.
“So much time has passed, I feel I can look at the material more dispassionately.”
Irvine Welsh, novelist
Whether this dispassionate look at Edinburgh’s needle-sharing era can sustain a commercial life on tour after its Haymarket run remains to be seen as audiences encounter the musical’s blend of dark subject matter, original songs, and classic soundtrack cuts.
