The remarkable Klaus Kinski was Herzog’s muse and nemesis over five films. This documentary portrait traces the love-hate relationship that nevertheless produced some outstanding work and constituted one of the great actor-director partnerships. To put it mildly, theirs was a tempestuous relationship: on ‘Aguirre’, Herzog threatened to shoot Kinski if he left the set; on ‘Fitzcarraldo’, Kinski’s behaviour was so outlandish that some local Indians offered to kill him. Kinski made more than 150 films, but only his work for Herzog is truly memorable. Indeed, it is almost impossible to imagine Kinski without Herzog, and it’s equally true that some of the director’s greatest films owe much to Kinski’s incredibly intense performances. And it wasn’t all bad blood between actor and director, as this amusing film demonstrates.
