Production for Trainspotting 2 is finally underway, director Danny Boyle confirmed via Humans of Edinburgh's Facebook page.

Boyle revealed that filming for the sequel was on in Edinburgh, Scotland. Here's Boyle's quote from the Facebook post on March 9:

"We're up in Scotland filming Trainspotting 2 just now. I think what I love most about what I do is the variety, and being able to do something new every day. I get to meet such amazing people all the time. I think everyone's fear is doing something a robot can do, and getting stuck doing something repetitive. I feel very fortunate and grateful to be able to make films, and to be able to always have a choice in what I do. Coming back to Edinburgh has actually been really fascinating, since filming the first Trainspotting Edinburgh has changed dramatically. You can see the gentrification massively in the city."

The post is accompanied by a picture of Boyle smiling and all dressed up for winter. Renton (Ewan McGregor), Begbie (Robert Carlyle), Sick Boy (Johnny Lee Miller) and Spud (Ewen Bremmer) are set to return for the sequel, which has been written by Irvine Welsh.

Trainspotting 2 will open in theaters sometime in 2017.
