When news broke recently, on its 20th anniversary, that the film Trainspotting — Danny Boyle’s dirty, druggy cult classic of 1996 — would be getting a sequel, it was met with the kind of restrained glee you’d expect from the fashion crowd. Because even those who don’t know that the bombers seen on nearly every runway nowadays can be traced back to that worn by Ewan McGregor in his breakout role, or that the upcycled, ill-fitting style favored by Vetements derives from the Scottish grunge hit, know that few movies nailed the 90s like Trainspotting.

The untitled follow-up will be based on the novel Porno — by Irvine Walsh, author of Trainspotting — which follows original characters Mark Renton, Sick Boy, Begbie, and Spud as they regroup for more another round of exploits, this time of the skin-trade kind.

Speaking to the film website Collider, McGregor confirmed that ten years ago, when Porno was published, he wasn’t ready to embark on a film sequel. But the screenplay by John Hodge convinced him otherwise. “The script only arrived very recently, which was really, really, really good,” he said. “I think, if that had not happened, none of us would be into it. I think we’re all somewhat protective of what Trainspotting means to people, and what it means to us. None of us want to make a poor sequel to it.” He also revealed they’ll begin filming in Glasgow in May.
