Twenty years in the making, it sounds like Trainspotting 2 is ready to go! The movie will be a follow-up to the 1996 cult hit Trainspotting, with original director Danny Boyle saying it will be his next project. He revealed the big news this past weekend at the Telluride after-party for the "work-in-progress" screening of his latest movie, the biopic Steve Jobs. About getting the sequel off the ground, he had this to say to Deadline.

"All the four main actors want to come back and do it. Now it is only a matter of getting all their schedules together which is complicated by two of them doing American TV series."

The four main cast members in question, who headlined the original, include Ewan McGregor, Ewen Bremner, Jonny Lee Miller and Robert Carlyle. Kevin McKidd was also a main cast member, but his character died in the first Trainspotting. Kelly Macdonald was the female lead, and is expected to return as well. Right now, Jonny Lee Miller stars in the CBS drama Elementary. Robert Carlyle is one of the many characters on ABC's fantasy adventure series Once Upon a Time. Both shows are currently shooting the first half of their upcoming new seasons, with a break scheduled for later this fall. But will Porno start shooting that soon? It's more likely that Danny Boyle will wait for the summer hiatus.

Porno will follow the four main characters from Trainspotting twenty years after their harrowing bout with heroine addiction. The original's screenplay was written by John Hodge, based on Irvine Welsh's 1993 novel. It followed the misadventures of a group of drug addicts living in Edinburgh (though the film was mostly shot in Glasgow). It's not clear if the new movie will still be called Porno, or if the filmmakers will go with Trainspotting 2 as the title, which has more recognition power behind it. John Hodge is returning to write the sequel as well.

Danny Boyle calls John Hodge's new script terrific. The actors are all ready to return, but the film will only move forward once all of the actors' schedules are finalized. Though it may now be called Trainspotting 2, the story will still be based on Irvine Welsh's 2002 Porno novel. The book describes the characters of Trainspotting as their paths cross again, this time with the pornography business as the backdrop rather than heroin use (although numerous drugs, particularly cocaine are mentioned throughout). The book actually picks up on story threads that were seen in the movie, but not part of the original Trainspotting novel.

John Hodge is a longtime collaborator of Danny Boyle's. He has previously scripted A Life Less Ordinary, The Beach and Trance for the director. Prior to the first public screening of Steve Jobs this past weekend, Danny Boyle received the Telluride Medallion for his body of work. Clips shown during the ceremony included the iconic toilet-diving scene from Trainspotting. What do you think? Are you excited for Trainspotting 2?
