“I think we’re all sort of somewhat protective of what Trainspotting means to people, and what it means to us,”; he explains of why the sequel took 20 years to come together. “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.”;
