While doing the rounds for Steve Jobs, Danny Boyle told Vulture that the actors were wary about his next project, a sequel to his runaway classic, Trainspotting. “The actors were very fearful about a sequel as well,” said Boyle. “When it comes to doing another Trainspotting, they were very nervous, because for all of them, it’s a large part of their reputation and they feel very protective towards their character.” Novelist Irvine Welsh published the follow-up to Trainspotting, titled Porno, in 2002, but it was only recently that John Hodge, who adapted the first novel for the screen, finished the script for the second.
Ewan McGregor has read the script for the yet-to-be titled sequel and can cast his fears aside. "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," McGregor told Collider. "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 says that they'll begin shooting at the end of May, giving them plenty of time to decide if Trainspotting Porno is good or bad for SEO.
