"Stuart Sutcliffe: The Lost Beatle" explores the mystique surrounding the Beatles' original bassist, who left the band to follow a different muse and died from a cerebral hemorrhage at the age of 22. Told via interviews with an impressive array of Sutcliffe's family and friends - and through uniquely descriptive quotes from his letters - this hour-long documentary reveals a lot of intimate detail about Sutcliffe's transition from promising art-school student in Liverpool (and best friend of John Lennon) to reluctant musician (pressed into service by Lennon) to determined painter within the German avant-garde scene. A lot of Stu's story, as Beatles fans know, is set in Hamburg, during and after the days the group was a house band in the city's red-light district. Familiar tales of friction between Sutcliffe and Paul McCartney abound. But these are offset by a tremendous amount of fresh insight and detail offered by such important Beatles-saga figures as rocker Tony Sheridan, Klaus Voormann and - most crucially - Astrid Kirchherr, the photographer who influenced the Beatles' look and who became Sutcliffe's lover until his death. Interviewees include Stuart's fiancee and Beatles stylist/photographer Astrid Kirchherr, early Beatles manager Allan Williams, Stuart's sister Pauline Sutcliffe, Liverpool flatmate to Sutcliffe and Lennon, Rod Murray and esteemed American art historian and writer Donald Kuspit.
