Seeing as Irvine Welsh, the author of the “Trainspotting” novel, wrote a sequel to his well-regarded story about Scottish heroin addicts called “Porno” back in 2002, it’s always seemed like something of a possibility that Danny Boyle, the guy who directed the Trainspotting film, could get his crew of actors back together and shoot it as a sequel. There have always been concerns that have kept that from happening though; namely the fact that Boyle had a pretty public falling out with his Trainspotting star, Ewan McGregor, and the worry that “Porno” the novel isn’t really as good as “Trainspotting,” (so it might not be worth making into a movie). While talking to The Playlist, Boyle has revealed that he’s always wanted to make a Trainspotting sequel anyway, so he’s going to try to shoot for getting one into theaters in 2016, which would make it in time to celebrate the 20 year anniversary of the first film’s 1996 release. But what about all of those pesky concerns about “Porno” not really having what it takes to make for a good movie, and McGregor not really being so fond of Boyle anymore? Don’t worry, the director has them addressed.
