How 'Trainspotting' changed from page to screen to stage

Before it became a musical, Irvine Welsh's Trainspotting was a seminal book, film, and play.

Summary

• Trainspotting has been a book; a film; a play and now a musical
• Irvine Welsh returns to the musical contributing additional music and lyrics
• Caroline Jay Ranger directs

Thirty years after Danny Boyle's landmark movie hit our screens, Trainspotting the Musical is chugging into Theatre Royal Haymarket in the West End.

Based first on Irvine Welsh's gritty novel about working-class life in Edinburgh, Trainspotting has now spawned a play, a film, and a musical, as well as sequels and a prequel. The story of a group of young, disenfranchised men struggling with addiction and mass unemployment in Scotland struck a chord with readers and filmgoers alike.

Alongside launching the career of Ewan McGregor, Trainspotting became a cultural phenomenon. Now's your chance to see how it translates on stage — choose life, choose a job, and choose to book tickets to Trainspotting The Musical.

The Trainspotting book (1993)

Irvine Welsh’s story of drug abuse and unemployment in the late 1980s draws on the writer’s own experience of growing up in Leith, Edinburgh and becoming addicted to heroin. He was playing in punk-rock bands, which moved between Edinburgh and London, and after a series of arrests for petty crimes (as well as a suspended sentence) he cleaned up his act.

Trainspotting was his debut novel, and he has since written three sequels including Porno (2002), Dead Man’s Trousers (2018), and Men in Love (2025), as well as the prequel Skagboys, which was published in 2012.

The novel follows a group of friends, most of whom are heroin addicts: the novel’s protagonist and narrator Renton tries to get clean but can’t break the habit; handsome con artist Sick Boy is devastated when infant Dawn dies, likely due to neglect; child-like Spud is locked up for petty theft; and violent alcoholic Begbie can’t stop getting into fights. Life is tough, and the characters struggle to break free from the social and political challenges they are born into.

Split into seven sections, Trainspotting is non-linear, with most chapters narrated in first-person stream of consciousness. Others are written in the third person to present the thoughts and actions of several characters. The text is written in Scots dialect, featuring Edinburgh slang and phonetic spellings, to authentically capture the voices of the characters.

The novel was longlisted for the 1993 Booker Prize, but was rejected by the short list after offending two of the judges.

The Trainspotting play (1994)

Harry Gibson’s adaptation of Welsh’s story premiered at the Traverse Theatre in Edinburgh in 1994 — only one year after the book was published. It stays close to the original novel and regularly toured the UK in the 1990s. It premiered in the US in San Francisco in 1996 and won The Sunday Times Award for Best New Play.

In 2013, a new immersive production of Gibson’s adaptation was staged by In Your Face Theatre and Seabright Productions. Renamed Trainspotting Live, this 80-minute show has sold out at three Edinburgh Festival Fringe shows, played on tour, in London and in New York. The show returns to the fringe this year, playing from 6-30 August.

Speaking to The Herald in 2016, Gibson said: “I'm responsible for dirty theatre. What became known as in-yer-face theatre was hugely influential on telly shows like Skins and Shameless. The thing with Irvine is that he's totally non-judgemental, and he loves the dirty side of life anyway.”

The Trainspotting film (1996)

Danny Boyle’s seminal film starred Ewan McGregor in the lead role of Renton, with Ewen Bremner, Jonny Lee Miller, Kevin McKidd, Robert Carlyle, and Kelly Macdonald also in the cast. Welsh’s bleak, episodic book became a dark comedy in Boyle’s hands, with the director removing a lot of the amoral behaviour found in the book and giving the film a more cohesive structure. He also streamlined the character list, focusing more on the central friendship group.

The British Film Institute ranked the film 10th in its list of the Top 100 British films of the 20th century and, in 2004, Trainspotting was voted the best Scottish film of all time in a poll.

Trainspotting’s soundtrack has had a huge influence on popular culture, featuring the music of 1970s pop icons including Lou Reed and Iggy Pop, as well as techno-dance and Britpop music of the 1990s with bands like Blur and Pulp. Iggy Pop’s “Lust for Life” famously plays during the opening sequence when Renton is running through the streets of Edinburgh, hoping to escape security guards.

The original film’s cast returned to star in its sequel, T2 Trainspotting, which was released in 2017.

The Trainspotting musical (2026)

The Trainspotting musical comes to the stage 30 years after the film’s release, with Caroline Jay Ranger (Only Fools and Horses) as director, and Welsh returning to provide additional music and lyrics alongside Stephen McGuinness — a key figure in UK dance music.

The show had its world premiere at Theatre Royal Haymarket in the West End in July 2026, with the lead cast including Lewis Kidd as Renton, Sheridan Townsley as Sick Boy, Kieran Andrew as Spud, Frankie O’Connor as Begbie, and Finlay Paul as Tommy.

The musical hits many of the familiar beats of the previous film and novel, including key scenes such as Renton’s suppository-driven trip into the toilet, Spud’s soiled bedsheets, and the devastating loss of Alison’s baby. But it also tracks much more closely to the original novel, expanding the character list once again to include more scenes with the family and friends impacted by the decisions of the drug-taking friendship group, for example, Renton’s parents Cathy and Davie, as well as Spud’s mum and the men’s girlfriends. There is also a greater focus on the wider socio-political factors that have led to declining opportunities and mass unemployment such as Thatcher’s government.

While the musical features new music by Welsh and McGuinness, it also blends in iconic numbers from the film such as “Lust for Life”, “Perfect Day” and “Temptation”, as well as songs from the period like “Mad World”.

Following its West End premiere, the musical goes on a UK tour this autumn.
