After years of speculation, there will indeed be a sequel to Trainspotting.

The 1996 film was directed by Danny Boyle and it was based on Irvine Welsh’s novel of the same name.

A star-making performance by Ewan McGregor–not to mention brilliant turns by Robert Carlyle and Ewen Bremmer–made the film not only an instant classic, it’s considered to be the greatest Scottish movie ever made.

Here’s what we know about the sequel:

1. McGregor, Carlyle, Bremmer and Jonny Lee Miller are all on board to reprise their roles.
2. The sequel will be based on Welsh’s novel Porno, which was published in 2002.
3. Shooting will begin at the end of May.
4. Danny Boyle will be directing.
5. McGregor told Collider that the script is, “…really, really, really good.” He went on to add: “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.”
