Según ha publicado el Facebook de Humans of Edinburgh, el rodaje ya ha comenzado en Edimburgo con los miembros del elenco original, Ewan McGregor, Robert Carlyle, Johnny Lee Miller y Ewan Bremmer:

"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."
