""Joe Strummer: The Future Is Unwritten " is one artist's moving tribute to another: director Julien Temple's poetic evocation of the life of punk's greatest troubadour. Using archival footage, contemporary interviews and material from the former Clash frontman's own notebooks (lyrics, meditations and even doodles), Temple creates a fluid audiovisual pastiche of an extraordinary life. There's always slightly less than what we want, but that's testament to the richness of the content, which also includes heartfelt testimony from those who knew and appreciated Strummer, who died in 2002, including former bandmates Mick Jones and Topper Headon. In a way, the movie is like one of Strummer's songs: intensely personal and private, insightful yet elusive".
