Filmmaker Julien Temple chronicles the transformation of a self-described "mouthy little git," born John Mellor, into an antiestablishment icon known to the world as Joe Strummer. In his latest documentary, Temple uncovers the myth behind the front man of the seminal punk band the Clash.

Through previously unearthed interviews with Strummer himself and recollections of those who knew him best, Temple reveals a complex man who used his music as a bullhorn for his conscience--as well as a means to educate others about the injustices of the world. The film includes live concert footage spanning Strummer's career and tapes of his BBC radio program, all of which provide a fitting soundtrack to his distinctive and storied existence.

The performance footage would be fascinating on its own, but Temple probes beyond Strummer's mystique to reveal a person with his own flaws who could sometimes be idealistic to a fault. Temple has created a thoughtful and poignant portrait of a man many think they knew. 'Joe Strummer: The Future Is Unwritten' provides a rare glimpse into the man behind the legend of "punk rock warlord."
