There We Were, Now Here We Are… The Making of Oasis 2004 on netflix

A documentary made for television that looks back on the development and rapid rise of Oasis from being a band practicing nightly in the Boardwalk to one the biggest British bands of the last thirty years. Building from the formation of the band (with Liam apparently just fed up waiting for other bands to release records and decides to do something himself), the film uses contributions from key people really well to tell the story in an engaging way.
