Trainspotting

Danny Boyle's Trainspotting opened in 1996, three years after his Shallow Grave, and became the defining British film of its decade, at once a Cool Britannia document, a heroin epic, and a stylistic phenomenon that retrofitted MTV pacing into UK cinema. Adapted from Irvine Welsh's 1993 novel by John Hodge, the film won the BAFTA for Best Adapted Screenplay and helped launch Ewan McGregor, Robert Carlyle, Kelly Macdonald and Jonny Lee Miller as significant film actors.

Mark Renton (McGregor) and his Edinburgh circle (Spud (Ewen Bremner), Sick Boy (Miller), Tommy (Kevin McKidd) and the violently sober Begbie (Carlyle)) drift through unemployment, casual sex, theft and progressively serious heroin use. The film's structural conceit is that the addiction is the easy part; what's hard is the choosing-life sequence at the end, in which Renton's voice-over Choose Life monologue inverts itself across a betrayal.

The film's sequences (the toilet-of-the-Worst-Toilet-in-Scotland dive, the Edinburgh crawling-baby withdrawal, the Iggy Pop opening Sprint) are now embedded in British cultural memory. Boyle's commitment to a high-saturation, kinetic register, and to a soundtrack ranging from Pulp to Underworld to Brian Eno, made the film an enduring stylistic reference point. T2 Trainspotting (2017) returned to the cast twenty years on; the original remains the canonical version.

Why it's an Editor's Pick: The defining British film of the 1990s, and the work that proved a heroin tragedy could also be propulsive cinema. Almost thirty years on, the Choose Life monologue still works exactly as Welsh and Hodge intended.
