Joe Strummer fronted the Clash, the band once marketed as "The Only Band That Matters," and this film by Julien Temple tells his life without a single new interview shot for the camera. Strummer's own voice, pulled from old radio broadcasts and taped conversations, narrates throughout, so the film plays as a man talking about himself after his death at 50 from a heart attack in 2002. Temple builds the story the way he built his two Sex Pistols films, as a collage rather than a straight biography: rehearsal footage of the Clash, performances from Strummer's earlier pub-rock band, news clips, and even snippets of the animated "Animal Farm" cut in alongside the conventional timeline. The approach treats a life as more than a sequence of events, folding in the politics and half-formed ideas that shaped a working musician into a public conscience. The absence of a living, present-day Strummer becomes part of the film's point, a void the archival material can illustrate but never fill.
