Danny Boyle said a few weeks ago that Trainspotting 2 has already started filming - but it now looks like it doesn't officially begin until May.
The director broke the news that the much-anticipated sequel was underway in Scotland, saying: "Coming back to Edinburgh has actually been really fascinating… You can see the gentrification massively in the city."
However, Ewan McGregor has now said that it all starts for real in a couple of months' time; in May to be precise, and praised John Hodge's script.
"We haven't started yet, we start shooting at the end of May," he told Collider. "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."
The movie will hit cinemas sometime next year.
