Speaking to Collider, McGregor said: “It’s been 10 years since Irvine Welsh wrote the sequel novel, Porno, so it’s been a long time, a lot of speculation. For me, too! 10 years ago, I didn’t want to do it; I wasn’t ready to do it. Also, there was no script.”

“The script only arrived very recently, which was really, really, really good. I think, if that had not happened, none of us would be into it. I think we’re all sort of 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. So had we not been presented with the most extraordinary script, which we were, I think we wouldn’t be making the sequel. But because we were, we are.”

McGregor’s co-star Robert Carlyle has previously describe the sequel’s script as one of the best he’s ever read. “Honestly, it's one of the best scripts I've f****** read. I mean, ever. What John Hodge has done is just so clever,” the actor said in November.

“Obviously these four characters are 20 years older now and I've never seen a sequel that takes place 20 years after the original, so I think that gives it a certain unique quality,” he continued. “Without giving anything away, maybe some of them haven't really moved on. That's what the audience is going to have to go through with them.”
