The long-awaited follow-up, which will be helmed by original director Danny Boyle, is scheduled for release in 2017, editors at NME.com report.

The 1996 film was based on Irvine Welsh's novel of the same name, and the author released a sequel to Trainspotting, called Porno, in 2002, and a prequel to the series, Skagboys, in 2012.

Danny told reporters at the London premiere of his film Steve Jobs in October (15) that the prospect of making Trainspotting 2 is "worrying," adding, "We're going up to Scotland very early and we're going to do a week's workshop up in Edinburgh working on the script. And we're filming in May and June of next year.

"Obviously it's worrying because people will kill us if we made a bad job of it (sic). I will get absolutely crucified. But you have to thrive on that potential danger within it and if it feeds into it, you might get a decent film out of it..."

The director also assured fans that he is aiming to have the film ready in time for Trainspotting's 20th anniversary next year (16).

"Hopefully we can get it finished in time to release it in 2016 which is the 20th anniversary year. So yes, we're on it, and it's looking good," he says.
