Beatniks, Hippies, Flower Power, LSD, Make Love, Not War... It's another trip down Memory Lane as the roots of American counter-culture are once more analysed and interpreted. The usual suspects: Ginsberg, Kerouac, Cassady, Leary, Burroughs et al are all duly represented with archival footage, contemporary interviews, and the recollections of friends and fans. Even actors Johnny Depp, Dennis Hopper and John Turturro get in on the act by giving dramatic readings of some of the celebrated writers' words. The Source examines the near half century of influence that the Beat movement has spawned in arts, politics, society and culture. Oscar-winning director Chuck Workman culled some 200 sources as well as shooting original material. "This is a film about writers," he says. "I wanted to show the wealth of literature that the Beats created." Owen Levy
