The Klaus and Werner Show In his obscene, terminally cranky memoir, All I Need Is Love, Klaus Kin-ski saves a special dose of vitriol for director Werner Herzog. Les Blank's Burden of Dreams captures the pair's love-hate relationship, documenting the disasters, accidents, illnesses, and fights that dogged Herzog's three-hour-long, three-years-in-the-making epic Fitzcarraldo. In Fitzcarraldo, Kinski discovers that building an opera house in the Amazon is impossible; in Burden of Dreams, Herzog discovers that making a film in the Amazon is impossible. Ask Blank all about it (he'll be on hand) at a 6:30 p.m. screening of Burden of Dreams at the Goethe Institut, 530 Bush, S.F. Free; call 391-0370.
