During a Hot Press interview last April, controversial Scottish author Irvine Welsh spoke about the possibility of a sequel to the hugely successful Trainspotting movie, based on his follow-up novel, Porno.
“It’ll only happen if the script is good enough,” he told Olaf Tyaransen. “Nobody needs the money, and we don’t want to trash the legacy. The actors are 20 years older now, so we’d have to do something different.”
Now it would appear that the film – tentatively titled Trainspotting 2 – is almost definitely going to happen. Having just premiered his Michael Fassbender-starring Steve Jobs biopic at the Telluride Film Festival, director Danny Boyle revealed that, if scheduling allows, his next movie will be the long-awaited sequel to the 1996 cult classic that made his name.  
“All the four main actors want to come back and do it,” Boyle told Deadline. “Now it is only a matter of getting all of their schedules together which is complicated by two of them doing American TV series.”
The sequel will revisit the hedonistic characters of Renton, Begbie, Sick Boy and Spud a decade after the druggy events of Trainspotting. As the title of Welsh’s novel suggests, this time around they’re embarking into the seedy world of pornography.
John Hodge, the screenwriter of Trainspotting, as well as Boyle’s A Life Less Ordinary and The Beach, has already penned the sequel’s script, which Boyle has deemed “terrific.”
Actors Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle have all agreed to reprise their original roles for the sequel. Although Welsh’s follow-up novel was released in 2002, a number of factors kept it from going into production, most notably a serious falling-out between McGregor and Boyle (after Boyle reneged on a promise and passed over the actor for Leonardo DiCaprio in The Beach. However, the pair have since patched things up).  
Miller (“Sick Boy”) and Carlyle (“Begbie”) are the two actors currently complicating scheduling, with Miller starring in CBS’ Elementary and Carlyle playing a substantial reoccurring role in ABC’s Once Upon A Time.
Tweeting from his @IrvineWelsh account, Irvine Welsh commented, “Tying down the awkward cunt who played Mikey Forrester could be a deal-breaker. That boy is IN DEMAND.”
Needless to say, it was Welsh himself who made a cameo in the original movie as dodgy heroin dealer Forrester.
