The memorable run along Princes Street set the local context, but the majority of the scenes in the movie were played out here, shot in just seven weeks in the summer of 1995. Locations included Maryhill, Hopehill Road, Buchanan Street and Firhill.
Danny Boyle, Ewan McGregor, Jonny Lee Miller, Ewen Bremner, Kevin McKidd, Kelly Macdonald and Robert Carlyle all turned out to launch the movie in Glasgow with a premiere screening at the Odeon cinema on Renfield Street.
Here are 11 pictures to show why Trainspotting is the best Glasgow movie of the 1990s.

1. Trainspotting in Glasgow
Based on Irvine Welsh’s novel, Trainspotting, the film was an international success, making stars of its young Scottish cast including Ewan McGregor. Almost all the sets for the movie were built on an improvised soundstage at an old factory in Dennistoun but you can spot the city in many of the film’s most important scenes.
