Klaus Kinski is da` man Doc!!
Great movies.
I've read some articles on Kinski and Herzog. They had a love-hate thing going on, but on some of their movies (I think Fitzcarraldo particularly) they literally were trying to kill each other in the middle of the Amazon jungle. No namby-pamby Hollywood shit for these two, they were wasted, taking pot shots at each other while the crew cowered in fear. Fantastic!
