Updated with script information: “All the four main actors want to come back and do it,” the director tells Deadline’s Pete Hammond, who caught up with Boyle at the Telluride after-party for the “work-in-progress” screening of Steve Jobs with Michael Fassbender in the title role. “Now it is only a matter of getting all their schedules together which is complicated by two of them doing American TV series,” Boyle says.

Prior to the first-ever public screening of Steve Jobs, Boyle received a Telluride Medallion for his body of work, clips of which included a certain vivid public toilet-diving scene from Trainspotting. The long-anticipated and much-speculated sequel would follow by at least 20 years the ground-breaking 1996 Miramax release of Channel 4’s account about the grimly, grittily entertaining misadventures of drug addicts in Edinburgh (but film was shot mostly in Glasgow). The original was written by John Hodge, based on Irvine Welsh’s novel.

Boyle also told Deadline that Hodge’s script for what they’re calling Trainspotting 2 is terrific, that the actors all want to do it and reiterated that it will be the director’s next film depending on the actors’ U.S. TV schedules. Hodge wrote the sequel script based on Welsh’s Porno, which was the author’s own sequel to his original Trainspotting novel. Hodge also wrote the screenplays for Boyle-directed movies A Life Less Ordinary, The Beach and Trance.

Stars of Trainspotting included Ewan McGregor (who told the Guardian in June that he was “up for” a sequel), Jonny Lee Miller, Robert Carlyle, Kevin McKidd (whose character died in the original), Ewen Bremner and Kelly Macdonald. As for the pair of actors Boyle cited as working on U.S. TV shows, Miller plays Sherlock Holmes in Elementary on CBS, and Robert Carlyle, who said in July that a Trainspotting sequel is “closer than it’s ever been,” is a regular on ABC’s Once Upon A Time. Trainspotting cast members Kelly Macdonald appeared in HBO’s Boardwalk Empire, and McKidd appears on ABC’s Grey’s Anatomy.
