"The Future Is Unwritten," which recently premiered at the Sundance Film Festival, was assembled using a combination of old interviews collected from journalists as well as tapes of Strummer's BBC radio show. It features testimonials from members of the Clash as well Bono, Johnny Depp, Martin Scorsese, Courtney Love, Flea and John Cusack among many others.
The film was produced by documentary filmmaker Julien Temple, who was responsible for the definitive Sex Pistols documentary The Filth and the Fury as well as the infamous mockumentary The Great Rock 'n' Roll Swindle. Though Strummer tragically passed away in 2002, Temple had already shot many hours of footage to be used in the film.
Among songs from the 101'ers and Mescaleros the soundtrack includes the song "(In The) Pouring Rain" credited to Clash II. This was one of the unreleased songs played on tour during the band's Cut The Crap era. It is notable that the band is credited as "Clash II" and not simply "The Clash." While fans often deride the post-Combat Rock period and official band histories tend to ignore it, this may be the first time the Clash II moniker has been used on a non-bootleg recording.
