For those of you worried that the Trainspotting sequel may be nothing more than a pipe dream, your concerns will dissipate with the knowledge that filming is officially underway.
Danny Boyle confirmed the news in a post via Humans of Edinburgh's Facebook page where he revealed he had returned to the Scottish capital for the first time since filming his 1996 cult.
"Coming back to Edinburgh has actually been really fascinating, since filming the first Trainspotting. Edinburgh has changed dramatically," he wrote.
Things have changed quite a bit since the film's release in 1996: for starters, McGregor has since played Obi-Wan Kenobi in George Lucas' Star Wars prequels and Boyle is no longer a relative British newcomer but a globally successful Oscar-winning filmmaker (taking home the trophy for Slumdog Millionaire in 2009).
The sequel will be based on Welsh's sequel Porno which was released in 2002; the author and Carlyle - who played Begbie - are set to discuss the character's influence during a talk hosted by the Edinburgh International Book Festival (EIBF) in April.
The original centered on the lives of a group of heroin addicts residing in Edinburgh during the late Eighties.
No title or release date has yet been announced.
