1. Ewen Bremner was the original Renton
We know him as gangly, gormless Spud. But before the ‘Trainspotting’ film, Ewen Bremner played Renton in a stage version, first in Scotland then at London’s Bush Theatre. Bremner later admitted to being a bit aggrieved at not being considered for Renton: ‘I was being a stupid snob.’ The film's director Danny Boyle talked him into playing Spud.
