'Trainspotting' trivia and fun facts

The sex scene between Ewan McGregor and Kelly Macdonald had to be trimmed for the American release by a few seconds, mainly because it appeared that Diane - a schoolgirl in the film - seemed to be enjoying it too much.

In 2009, Robert Carlyle, who played Begbie, told a BAFTA interviewer that he played Begbie as a closeted gay man whose outbursts of violence were due to his "fear of being outed". Irvine Welsh, who wrote the movie's source novel, confirmed that he wrote the Begbie of the book to have an ambiguous sexuality, and agreed with Carlyle's interpretation of the film's version of the character.

Ewen Bremner (Spud) had previously played Renton in a stage adaptation of the novel.
